Abstract:
Background: Midline laparotomy is the most common technique of abdominal incisions in both emergency and elective settings. Wound dehiscence is related to several factors pertaining to patient besides suture material and method of closure. This study tries to compare continuous sutures with x-interrupted sutures in mass closure of midline laparotomy wound in patients undergoing emergency midline laparotomy for acute peritonitis.Methods: A total of 60 patients undergoing emergency midline laparotomy for secondary peritonitis were considered for the study, 30 of whom underwent closure of abdominal wall with continuous sutures (Group A) and the other 30 with x-interrupted sutures (Group B) using non-absorbable, monofilament, polypropylene suture. Necessary preoperative data, the time required for rectus closure, length of the suture material required, post-operative complications like surgical site infection, wound dehiscence were analyzed.Results: The groups were comparable in means of age and sex distribution. Group A was found to have lesser time for closure of rectus, lesser suture length and lesser suture to wound length ratio when compared with Group B. Surgical site infections were similar in both groups. Patients with rectus sheath sutured in x-interrupted sutures (n=2) had significantly less wound dehiscence as compared with continuous sutures (n=8) (p<0.05).Conclusions: Interrupted -X suture method of suturing reduces post-operative wound dehiscence, although requires more suture and consumes more time than the continuous method of suturing.

Abstract:
When placing dental implants, there may be a surgical flap to reposition. The flap can be sutured or held in place with a stent that protects the flap and maintains its position and immobility. Use of a bis-acryl stent may be preferable to sutures or other materials in many cases. Bis-acryl is easily applied from an auto-mixing gun. Stents may be preferable to sutures in that there is no “wicking effect,” where bacteria colonize the suture beneath the healing surgical wound. Additionally, many times there is no submucosa to suture to, and the sides of the wound may not allow appropriate flap positioning and immobility with sutures. In these situations an acryl stent may be placed for easy and proper flap positioning and healing.

Abstract:
The paper reports about different kind of sutures, their suitability and performance. An ideal suture should possess many characteristics such as - easy to handle, bio-compatibility, minimal tissue reaction, resistance to bacterial growth, adequate tensile strength and elasticity, knot security, strength loss versus healing rate of tissues. Selection of suture is often very complex for satisfying host of physical, mechanical and biological properties, and fulfilling contradictory requirements in varied applications. The paper develops an understanding about the selection of suture depending on the varied requirement. Past research work pertaining to the development of suture as reported in this paper, provides insight about the suitability of different surgical sutures and possible direction of future research.

Abstract:
This is a review of surgical options for posterior chamber intraocular lens (IOL) fixation in the absence of adequate capsular support. The indications, techniques, and outcomes for posterior chamber iris-sutured and scleral-fixated IOLs, including trans-scleral sutured and trans-scleral tunnel glued fixation, are reviewed. Iris-sutured IOL fixation may be appropriate in cases in which small corneal incisions with a foldable IOL are desired, but are only possible in cases of adequate iris tissue, and may be complicated by pupil ovaling and iris trauma, which can lead to prolonged inflammation in some studies. Scleral-sutured IOL fixation does not require robust iris tissue and decreases the risk for iris trauma, but is technically more demanding, may require larger incisions, and poses potentially more posterior segment complications. There are also ongoing concerns for suture exposure, erosion, and late suture breakage and IOL dislocation. Scleral tunnel-glued IOL fixation is a more recent innovation that avoids sutures and concerns for suture-related complications, and can be completed through smaller incisions with a foldable IOL. However, long-term studies are pending.

Abstract:
Objective: to study the effect of various types of suture materials, potentially suitable for cardiovascular surgery, on experimental surgical outcomes. Materials and methods. Polypropylene sutures (Prolene 6/0), titanium nickelide (TiNi) sutures (6/0) and absorbable polydioxanone sutures (Monoplus 6/0) were used in the study. Male Wistar rats were used for in vivo studies. The effect of suture materials on abdominal adhesions was studied. In vivo calcification process was examined, and response of blood components in contact with suture materials was also assessed in vitro. Results. There is a negative inflammatory response to suture materials. The severity of this response depended on the type of material used. Polypropylene sutures demonstrated the most severe inflammatory response provoking massive adhesion formation. In addition, large calcium deposits were found both in the suture area and in the thickness of the biomaterial, stitched with prolene and implanted subcutaneously in the rats. Titanium nickelide sutures showed high hemocompatibility and biocompatibility. The Monoplus sutures caused minimal inflammatory response and provoked calcification of the biomaterial to a lesser degree. Conclusion. The suture material could have significant effects on surgical outcomes and could cause postoperative complications.

Abstract:
Taking into account the peculiarities of the blood supply to the liver and the structure of its parenchyma, and, as a result, considerable difficulties in providing reliable hemostasis without additional traumatization, a surgeon needs to be careful when performing a surgical manipulation. Despite a large number of modern methods for stopping parenchymal bleeding, many practi-tioners give preference to classic methods of hemostasis, including ligation of bleeding vessels in the bulk of the organ using specialized sutures. One of the most serious complications of the use of suture material is cutting of organ tissue, which leads to enhanced bleeding and expansion of the area of damage. At the moment, the tactics of choosing suture material for surgical procedures is empirical. In this context, the aim of this study was to assess the physico-mechanical properties of suture material regarding its structure, and to develop a criterion for choosing surgical sutures for surgical procedures. For the study, the liver was removed out of corpses of males of 35 to 40 years of age, after which separate sections of 7.574 cm in size were obtained from it. Then a wound 3 cm long and 2 cm deep was made. The wound was sutured with a simple interrupted suture without tightening, but with application of one simple half-node. For suturing, catgut, twisted capron and polyglycolide thread were used. Attention was paid to the maximal force applied at the moment of cutting (Fmax) and the degree of pulling the thread at the moment of cutting (Lu). The analysis of the data was based on comparison of Fmax and Lu parameters. This method permits to refuse from the empirical approach to the choice of suture material for operations on the liver, and to develop a criterion for choosing surgical sutures.

Abstract:
ABSTRACT Any suture material, absorbable or nonabsorbable, elicits a kind of inflammatory reaction within the tissue. Nonabsorbable black silk suture and absorbable polyglycolic acid suture were compared clinically and histologically on various parameters. Materials and methods This study consisted of 50 patients requiring minor surgical procedure, who were referred to the Department of Oral and Maxillofacial Surgery. Patients were selected randomly and sutures were placed in the oral cavity 7 days preoperatively. Polyglycolic acid was placed on one side and black silk suture material on the other. Seven days later, prior to surgical procedure the sutures will be assessed. After the surgical procedure the sutures will be placed postoperatively in the same way for 7 days, after which the sutures will be assessed clinically and histologically. Results The results of this study showed that all the sutures were retained in case of polyglycolic acid suture whereas four cases were not retained in case of black silk suture. As far as polyglycolic acid suture is concerned 25 cases were mild, 18 cases moderate and seven cases were severe. Black silk showed 20 mild cases, 21 moderate cases and six severe cases. The histological results showed that 33 cases showed mild, 14 cases moderate and three cases severe in case of polyglycolic acid suture. Whereas in case of black silk suture 41 cases were mild. Seven cases were moderate and two cases were severe. Black silk showed milder response than polyglycolic acid suture histologically. Conclusion The polyglycolic acid suture was more superior because in all 50 patients the suture was retained. It had less tissue reaction, better handling characteristics and knotting capacity.

Abstract:
Selection of appropriate suture material is important for successful healing; it is based principally on the propertiesof suture, the type of the tissue to be sutured and the condition of the wound. The mechanical and biological propertiesof a suture and the suture’s size should correlate well to type and properties of the tissue to be sutured. Strategy of sutureselection for specific tissues is discussed. Presence of sutures in a wound can increase the rate of infection of the wound. Theseverity of the infection is related to the suture’s properties when the wound is clean. Closure of infected wounds should beavoided. Stapling is an alternative method for wound closure and offers a significant reduction in the operative time. Varioustypes of staplers are available, depending on type of the tissue and the surgical procedure. Skin staples are widely usedin the skin and other tissues. The use of vascular clips is an alternative way to ligate blood vessels. Tissue adhesives arematerials that can also be used in closure of specific types of wounds. Surgical mesh is useful for closure of large defects.

Abstract:
Despite the latest polymer materials and surgical suturing techniques, the knot will always be the weakest point of the tied suture loop. In theory, the knot must be as small as possible to prevent an excessive amount of tissue reaction and a delay in healing. There have been reports suggesting that topical cyanoacrylate adhesives could have a reinforcing effect on a surgeonâs knot. Such an outcome could lead to the elimination of knot slippage and the unsatisfactory performance of some surgical knots. The main purpose of this study was to determine if cyanoacrylate adhesive could have a significant reinforcing effect on typical suture types and sizes when tied as a surgeonâs knot. The second aim was to evaluate if the cyanoacrylate adhesive could replace an additional throw in the surgeonâs knot so as to achieve an equivalent mechanical performance. The topical cyanoacrylate adhesive LiquiBand® was combined with six different suture materials (TicronTM, SurgidacTM, Ethilon*, Nurolon*, BiosynTM and PDS*II) in four different sizes (USP 5-0, USP 3-0, USP 0 and USP 1). The surgeonâs knot (2=1) with and without one (2=1=1) and two additional throws (2=1=1=1) were tied in a reproducible way and mechanically tested. Six dependent variables were used to evaluate the performance of each knot with and without adhesive. The performance criteria were: the force at loop failure, the maximum loop-holding force, the loop holding capacity, the knot efficiency, the knot elongation efficiency and the loop distraction. From the results and from scanning electron microscopic observations of the reinforced knots, the cyanoacrylate adhesive was found to significantly improve the knot performance. The improvement was superior with braided sutures and with absorbable polymer sutures. The reinforcement was more significant with thicker suture sizes and with the plain surgeonâs knot. Finally, it was found that, according to the six performance criteria, the cyanoacrylate adhesive could not replace an additional throw in the surgeonâs knot.

Abstract:
Um sistema para auxílio à cirurgias oftálmicas foi desenvolvido com o objetivo de se minimizar o astigmatismo induzido devido ao formato irregular da córnea pelo ato de sutura. O sistema projeta 48 pontos de luz no filme lacrimal da córnea, provenientes de LEDs, dispostos num diâmetro precisamente circular. O deslocamento, a dimensão e a deformação da imagem refletida destes pontos luminosos são analisados proporcionando a ceratometria e a circularidade da sutura. O intervalo de medidas do sistema é de 32D - 55D (astigmatismos até 23D podem ser medidos) e um sistema para calibração do sistema foi projetado para manter o sistema calibrado. Esferas de aço de precisão foram submetidas ao sistema e uma correlação de 99% entre as medidas obtidas e os valores dos fabricantes foi obtida. O sistema foi testado em 13 voluntários para avaliação de sua aplicabilidade clínica e comparado a um ceratômetro comercial Topcon OM-4. Os fatores de correlação entre o sistema desenvolvido e o Topcon OM-4, para o astigmatismo, foi de \'R POT.2\' = 0,92, e em relação ao eixo, o fator é \'R POT.2\' = 0,99. O sistema indica que o cirurgião deve obter uma circularidade \'> OU =\' 98% para que astigmatismos acima de 3D não sejam induzidos na sutura.
A system for ophthalmic surgery support has been developed in order to minimize the residual astigmatism due to the induced irregular shape of the cornea by corneal suture. The system projects 48 light spots, from LEDs, displayed in a precise circle at the lachrymal film of the examined cornea. The displacement, the size and deformation of the reflected image of these light spots are analyzed providing the keratometry and the circularity of the suture. Measurements in the range of 32D - 55D (up to 23D of astigmatism are possible to be obtained) and a self-calibration system has been designed in order to keep the system calibrated. Steel precision spheres have been submitted to the system and the results show 99% of correlation with the fabricant\'s nominal values. The system has been tested in 13 persons in order to evaluate its clinical applicability and has been compared to a commercial keratometer Topcon OM-4. The correlation factors are 0,92 for the astigmatism and 0.99 for the associated axis. The system indicates that the surgeon should achieve circularity \'> OR =\' 98% in order to do not induce astigmatisms over 3D.

Coxofemoral luxations are a common traumatic injury seen in small animal practice, representing up to 90% of all luxations in dogs and cats. Despite the variety of surgical techniques available for the management of this condition, none seem to be ideal, as almost every surgical procedure has complications and drawbacks associated with it. However, extra-articular techniques have been described in order to avoid potential complications and studies have reported good or excellent clinical results with low rates of complications. In this study, we described and evaluated a modification of the extra-articular iliofemoral suture placement technique, originally described by Slocum and Devine (1987), through the application of two bone anchors and a crimping system, and reported complications associated with the procedure. The study sample comprised 7 dogs and a minimum of 4 weeks follow-up period was required. The overall complication rate was 29% (2/7), including surgical wound infection and reluxation. The results of this study suggest that the extra-articular iliofemoral suture with bone anchors appears to be an effective surgical technique for the treatment of craniodorsal coxofemoral luxations, but further research is necessary to investigate the factors associated with patient selection that might justify some of the postoperative complications identified.
RESUMO - Extra - articular iliofemoral suture placement with bone anchors : surgical option for resolution of craniodorsal coxofemoral luxations in dogs - As luxações coxofemorais são uma lesão frequente em clínica de animais de companhia, representando até 90% de todas as luxações que ocorrem em cães e gatos. Apesar da variedade de técnicas cirúrgicas disponíveis para a sua resolução, nenhuma parece ideal, pois quase todos os procedimentos cirúrgicos apresentam complicações e inconvenientes associados. Encontram-se descritas técnicas extra-articulares que visam evitar potenciais complicações e estudos demonstram bons a excelentes resultados com uma taxa de complicações baixa. Neste estudo descrevemos e avaliámos uma modificação da técnica de colocação de uma sutura extra-articular iliofemoral, descrita originalmente por Slocum e Devine (1987), aplicando duas âncoras ósseas e um sistema de fixação, descrevendo as complicações associadas com este procedimento. A amostra compreendeu sete cães, tendo sido requerido um período mínimo de 4 semanas de acompanhamento. Foram verificadas 29% (2/7) de complicações, incluindo infeção da sutura e reluxação. Os resultados deste estudo sugerem que a técnica de sutura extra-articular iliofemoral com âncoras ósseas parece ser um método eficaz para o tratamento de luxações coxofemorais craniodorsais, mas mais estudos são necessários para investigar os fatores associados com a seleção do paciente que podem ter justificado algumas das complicações pós-operatórias identificadas.

Abstract:
UVOD: Ingvinalna hernioplastika predstavlja najučestaliju operaciju u abdominalnoj hirurgiji. U istorijatu herniologije su se razvijale različite ideje, te iz njih nastale operativne metode, koje su imale za cilj formiranje kvalitetnog vezivnog tkiva na mestu kilnog defekta. Danas postoje brojne hirurške tehnike, bazirane na tenzionim ili beztenzionim principima, uz primenu hirurških mrežica, otvorenim pristupom, kao i laparoskopskim tehnikama. Zajednički cilj navedenih metoda je kreiranja idealne hernioplastike ingvinalnih kila. I pored postojanja ogromnog broja hirurških procedura i tehnika, još uvek ne postoji tzv. »prava hernioplastika« koja bi zadovoljila sve potrebne zahteve vezane za problem ingvinalnih hernija. CILJ I HIPOTEZA: Cilj rada je bio da se napravi uporedna analiza između dve različite hirurške tehnike otvorenim pristupom, konvencionalne tenzione suturne hernioplastike, te beztenzione tehnike, uz korišćenje hirurških mrežica ( mesh ). Korišćeni su sledeći parametri tokom istraživanja: određivanje nivoa postoperativnog bola prema numeričkoj skali, vizuelno-analognoj te kategorijskoj skali bola; određivanje samostalne fizičke aktivnosti; (savijanje nogu, naprezanje trbušnih mišića, ustajanje) u neposrednom postoperativnom periodu; gradacija nivoa mišićne snage, određivanje vremenskog perioda kada se pacijenti uspevaju vratiti svojim svakodnevnim aktivnostima i radnim obavezama; određivanje stope postoperativnog morbiditeta i mortaliteta te određivanje stope ranog recidiva bolesti. RADNA HIPOTEZA: Beztenzionu ingvinalnu hernioplastiku karakteriše znatno manja operativna trauma, što ima za posledicu manji lokalni i generalizovani odgovor organizma na stres. Kod bolesnika operisanih beztenzionom metodom očekuje se manji intenzitet bola, kraće zadržavanje u hospitalnim uslovima, manji procenat postoperativnih komplikacija, brži povratak uobičajenim fizičkim i radnim aktivnostima i znatno manji stepen recidiva bolesti. Pretpostavlja se da beztenziona ingvinalna hernioplastika u poređenju sa konvencionalnom uzrokuje manju nelagodnost za pacijente, znatno manji postoperativni bol i bolju mišićnu aktivnost. Poboljšanje mišićne aktivnosti ogleda se u lakšoj vertikalizaciji, kvalitetnijem kretanju uz manje bolan hod, bez povijanja tela na stranu operativne rane. MATERIJAL I METODE: Istraživanje je prospektivna, kliničko- statistička studija sa praćenjem parametara (preoperativnih, intraoperativnih i postoperativnih) kod svakog operisanog bolesnika. Studija je obuhvatila seriju od 200 pacijenata hospitalizovanih na Klinici za abdominalnu, endokrinu i transplantacionu hirurgiju Kliničkog centra Vojvodine, od decembra 2002. do avgusta 2007.godine, svrstanih u dve jednake grupe po 100 pacijenata, odabranih metodom slučajnog izbora. Prva, ispitivana grupa obuhvatila je pacijente operisane beztenzionim procedurama, druga, kontrolna grupa je obuhvatila pacijente operisane konvencionalnim, tenzionim tehnikama. Korišćeni metod rada je kliničko statistički sa praćenjem svih potrebnih fizioloških parametara, a dobijeni rezultati su analizirani i međusobno upoređivani statističkim metodama multifaktorijalne analize. Pronađene vrednosti su međusobno upoređene parametrijskim i neparametrijskim testovima značajnosti na nivou p<0.05. REZULTATI: komparacija između dve ispitivane grupe je vršena tokom preoperativnog, intraoperativnog i postoperativnog perioda, različitim statističkim parametrima. Konstatovana je, statističkom analizom, homogenost grupa u smislu starosne dobi i polne distribucije, kao i lokalnog preoperativnog nalaza vezanog za tip, veličinu i lokalizaciju kila, kao i spram klasifikacije hernija. U sledećim parametrima je ustanovljena statistički signifikantna razlika: postoperativni bol, gradacija mišićne snage, rana fizička aktivnost, količina utrošenih analgetika, dužina hospitalizacije, prisutnost obostranih kila, povratak radnim aktivnostima i obavezama, postoperativne komplikacije i recidiv bolesti. Dobijeni podaci su prikazani tabelarno, te delom u vidu grafikona i dijagrama. ZAKLJUČCI: 1. Kod pacijenata operisanih beztenzionom metodom evidentan je znatno manji postoperativni bol i brži oporavak i povratak uobičajnim dnevnim i radnim aktivnostima 2. Proceduru treba izvoditi u svim slučajevima sa prisutnim velikim defektima i razorenim zadnjim zidom ingvinalnog kanala 3 Beztenzionu hernioplastiku karakteriše manji broj recidiva u poređenju sa otvorenim tenzionim hernioplastikama. 4. Pacijenti sa bilateralnim ingvinalnim i recidivnim hernijama imaju punu indikaciju za izvođenje beztenzione herioplastike sa ugradnjom mesh-a. 5. Preduslov za uspešno obavljenu beztenzionu hernioplastiku je primena dovoljno velike proteze, odnosno mesh-a, dimenzija 15 x 10 cm.
INTRODUCTION: Inguinal hernioplasty is the most common surgical procedure in abdominal surgery. In the history of herniology have developed different ideas, and from them emerged operational methods, which are aimed at educating quality of connective tissue at the site of the hernia defect. Nowadays, there are numerous surgical techniques, based on the tensioned or tension-free principles, with the use of surgical mesh for open access as well as laparoscopic techniques. Common goal of these methods is creating ideal inguinal hernioplasty despite the existence of a huge number of surgical procedures and techniques, there is still no so-called »Proper hernioplasty " that would satisfy all the necessary requirements related to the problem of inguinal hernia. AIM AND HYPOTHESIS: The aim of this study was to make a comparative analysis between two different open access surgical techniques conventional tension hernioplasty and tension-free techniques, with the use of surgical mesh .The following parameters were used during the research: determining the level of postoperative pain according to a numerical scale, visual analogue scale and categorical scale of pain; determining the initial independent physical activities: (bending the legs, straining abdominal muscles, getting up) in the immediate postoperative period; gradation levels of muscular strength, determination period when patients can return to their usual daily activities and work duties; determining the rate of postoperative morbidity and mortality and to determine rates of early recurrence of the disease. WORKING HYPOTHESIS: Tension-free inguinal hernioplasty characterized by significantly less operative trauma, which results in smaller local and generalized body's response to stress. In patients operated by the tension. free method is expected to lower the intensity of pain, a shorter stay in the hospital setting, a smaller percentage of postoperative complications, faster return to normal physical and occupational activities and much lower degree of disease recurrence. It is assumed that the tensional. free inguinal hernioplasty compared with conventional causes less discomfort for patients, significantly less postoperative pain and better muscle activity. Better muscle activity is reflected in a facilitated mobilization, quality of movement and less painful gait, without bending the body at the side of the surgical wound. MATHERIAL AND METHODS: The research was a prospective, clinical-statistical study of the monitoring parameters (preoperative, intraoperative and postoperative) in each of the operated patients. The study involved a series of 200 patients hospitalized at the Clinic for Abdominal, Endocrine and Transplantation Surgery, Clinical Center Vojvodine, from December 2002 to August 2007, divided into two groups of 100 patients, randomly chosen. First, the test group consisted of patients operated by the tension-free procedures, the other, the control group consisted of patients operated on conventional techniques. The method used is the work of clinical statistical tracking of all necessary physiological parameters, and the results were analyzed and compared with each other with multivariate statistical methods of analysis. Found values are compared with each other parametric and non-parametric tests of significance at p <0.05. RESULTS: The comparison between the two study groups was performed during the preoperative, intraoperative and postoperative period, using various statistical parameters. It was noted using the statistical analysis, the homogenity of the groups in terms of age and sex distribution, as well as local preoperative findings related to the type, size and location pounds as well as towards the classification of hernias. In the following parameters is statistically significant difference: postoperative pain, graduations of muscle strength, healing of physical activity, the quantity of analgesics, length of hospitalization, the presence of bilateral hernias, the return of work activities and responsibilities, postoperative complications and recurrence. The data are presented in tables, and partly in the form of graphs and charts. CONCLUSIONS: 1. In patients operated by the tension-free obvious method is significantly less postoperative pain and faster recovery and return to usual daily and work activities 2. The procedure should be performed in all cases with the presence of large defects and lacerated back wall of the inguinal canal 3. Tension-free hernioplasty is characterized by a smaller number of recurrence compared with conventional hernioplasty 4. Patients with bilateral inguinal hernias and recurrent have a full indication of the performance of the tension-free hernioplasty with the installation of mesh. 5. A prerequisite for the successful work carried out tension-free hernioplasty application is large enough prosthesis ( mesh ), measuring 15 x 10 cm.

Abstract:
A perfuração gástrica por endoscopia é a consequência de alguns de seus procedimentos, e atualmente, com o advento das cirurgias endoscópicas translumenais por orifícios naturais, um meio de manipulação dos órgãos abdominais. Esse é o motivo pelo qual os endoscopistas estão procurando um reparo endoscópico seguro. O objetivo foi avaliar a factibilidade e os resultados do fechamento da abertura gástrica similar àquelas realizadas nos procedimentos cirúrgicos endoscópicos translumenais por orifícios naturais utilizando-se o T-Tag associado à câmara plástica protetora. Sob anestesia geral, dez porcos Landrace foram submetidos a uma perfuração gástrica calibrada em 18 mm de diâmetro. A abertura foi fechada pelo novo método apresentado, composto de fios cirúrgicos conectados em uma âncora metálica (T-Tag) posicionados pela parede gástrica através de uma agulha. Uma câmara protetora plástica foi adaptada à extremidade distal do endoscópio para proteger os órgãos abdominais adjacentes da punção da agulha fora do estômago. Seis dispositivos T-Tag foram posicionados na maioria dos casos e os fios atados com um apertador de nó metálico endoscópico formando três pontos de sutura. O teste de vazamento foi realizado com uma pinça endoscópica e distensão da câmara gástrica com ar. Os animais receberam líquidos no mesmo dia do procedimento. Uma dose de antibiótico diária por dois dias foi administrada. Nenhuma complicação foi detectada no período pós-operatório. Um mês depois, a endoscopia revelou a presença de cicatriz em todos os animais, e a maioria apresentava materiais da sutura aderidos à superfície mucosa da região. A região do antro gástrico apresentava poucas aderências identificadas na laparotomia realizada no mesmo momento. O reparo endoscópico utilizando o T-Tag e a câmara protetora plástica é factível, fácil de ser realizada e seguro. São necessários estudos adicionais para mostrar o real valor desse tipo de procedimento
The endoscopic gastric perforation is a consequence of some endoscopic procedures and now a way to manage abdominal organs. This is the reason why endoscopists are studying a safe endoscopic repair. The objective was to evaluate feasibility and results of the gastric opening closure similar to those performed in natural orifice translumenal endoscopic surgery procedures using T-Tag associated with the plastic protection chamber. Ten Landrace pigs underwent a gastric perforation of 1.8 cm in diameter under general anesthesia. The opening was repaired with stitch assembled in a T-Tag anchor placed through the gastric wall with a needle. A plastic transparent chamber, adapted to the endoscope tip protected the abdominal organs from the needle puncture outside the stomach. Six T-Tags were placed in most cases and the stitches were tied with a metallic tie-knot, forming three sutures. The leakage test was performed with a forceps and by air distention. The animals received liquids in the same operative day. One daily shot antibiotic during two days was used. No complication was detected in the postoperative course. One month later the endoscopy revealed a scar in all animals, and the majority of these with suture material. The antral anterior gastric wall was clear with few adhesions in the laparotomy performed in the same time. The endoscopic repair using T-Tag and a protector chamber is feasible, easy to perform and safe. Further studies are needed to show the real value of this kind of procedure

Abstract:
Bakgrund: Postoperativa sårinfektioner drabbar ca 2,3 % av de patienter som genomgått ett kirurgiskt ingrepp i svensk hälso- och sjukvård. Dessa infektioner kan ge upphov till förlängd vårdtid, ytterligare kirurgiska ingrepp och ökad mortalitet. Postoperativa sårinfektioner innebär ett lidande för patienten samtidigt som det är kostsamt för sjukvården. Inom sjukvården används utarbetade arbetssätt för att minska riskerna för att patienten ska drabbas. Samtidigt utvecklas och studeras nya metoder i det preventiva arbetet mot postoperativa sårinfektioner, exempelvis suturer belagda med antibakteriella substanser. En av dessa är triklosanbelagda suturer. Dock råder viss oenighet om dess preventiva effekter och roll i det förebyggande arbetet mot postoperativa sårinfektioner. Syfte: Studiens syfte var att undersöka om suturer med beläggning av triklosan har en förebyggande effekt mot postoperativa sårinfektioner. Metod: Studien utformades som en systematisk litteraturstudie med metaanalys av 7 randomiserade kontrollerade studier. Dessa studier hade en uppföljningstid om 30 dagar samt använt bedömningskriterier för förekomst av postoperativa sårinfektioner enligt CDC, Centers for Disease Control and Prevention. Resultat: Inget statistiskt signifikant resultat kunde erhållas gällande triklosanbelagda suturers preventiva effekt mot postoperativa sårinfektioner. (RR=0,8, 95 % CI=0,63-1,02, p=0.07). Slutsats: Studien indikerar att triklosanbelagda suturer inte rutinmässigt bör användas i preventivt syfte mot postoperativa sårinfektioner. Ytterligare forskning behövs på området.
Background: Approximately 2,3 % of the patients undergoing surgery in Swedish healthcare develop surgical site infections. These infections are often associated with prolonged hospital stay, additional surgical procedures and increased mortality. Surgical site infections cause patient suffering and increase healthcare costs. In healthcare, standard guidelines and work methods are used to prevent patients from developing surgical site infections. New methods to reduce the risk of surgical site infections are being developed and studied, such as sutures with antibacterial coating. One of these is Triclosan-coated sutures. However, there is some disagreement on its preventive effects and role in reducing surgical site infections. Aim: The aim of this study was to investigate if Triclosan-coated sutures have a preventive effect against surgical site infections. Method: This study was conducted as a systematic literature review with meta-analysis of 7 RCT. These studies all had a follow up time of 30 days and used the criteria of CDC, Centers for Disease Control and Prevention, to identify surgical site infections. Result: This study showed no statistically significant results of Triclosan-coated sutures preventive effect against surgical site infections. (RR=0,8, 95 % CI=0,63-1,02, p=0.07). Conclusion: This study indicates that Triclosan-coated sutures should not be used routinely to prevent surgical site infections. More studies are needed.

Abstract:
Introduction: The nonsyndromic orofacial cleft (OC) is the fourth birth defect and the most common craniofacial malformation. The primary cleft repair surgery in the lip (cheiloplasty) or in the palate (palatoplasty) should be more aesthetic and functional, due to the nose and lip aesthetic side in people with OC has a value which goes beyond the human vanity, it is primordial to the child’s personality formation and his or her relatives. Objective: The objective of this study was to evaluate the cheiloplasty aesthetic results in individuals with unilateral cleft lip, using two different materials for cutaneous synthesis. Methodology: A randomized controlled clinical trial was performed, at the Sociedade Especializada em Atendimento ao Fissurado do Estado de Sergipe (SEAFESE). All subjects who underwent queiloplasty at SEAFESE between October 2014 and June 2017 participated in this study, constituting a population of 50 individuals. The control group had as material for cutaneous synthesis the polyglactin 910 reabsorbable suture and the experimental group had the octyl-2- cyanoacrylate tissue adhesive. These individuals were evaluated by six blinded evaluators with one month and six months post-surgery, at which time standardized frontal face pictures were taken. The esthetical face evaluation was performed using the Visual Analogue Scale (VAS), the Cosmetics Scale Evaluation proposed by Singer and the Classification Scale proposed by Mortier. In addition, an anthropometric analysis proposed by Pietruski was performed. Results: The population sociodemographic profile is an individual with an average age of 3.2 years, with monthly family income below two minimum salaries, most of them are from countryside and have pre-foramen cleft. About the cheiloplasty aesthetic results, in the one-month post-operative follow-up there was no significant statistical difference for VAS and for the Mortier Scale. But in the Singer Scale, the tissue adhesive presented better results for the variables: height, color, hatch marks or suture marks and overall appearance. In the six-month postoperative follow-up, there was no significant statistical difference for VAS as well. However, there was a difference, for the Singer Scale (width, color and hatch marks or suture marks) and in the Mortier Scale (scar and red lip), when better cosmetic results were noticed with the adhesive. In the anthropometric analysis proposed by Pietruski, when the two cutaneous synthesis materials were compared, a significant statistical difference was observed in three of the nineteen parameters evaluated. Finally, about the postoperative complications, there was only one surgical wound partial dehiscence in the control group. Conclusion: The tissue adhesives presented a superior cosmetic result when it was compared to the resorbable sutures. In six-month postoperative follow-up, the adhesive presented superior results in the anthropometric analysis proposed by Pietruski and in the scales proposed by Singer and by Mortier. In the comparison between plastic surgeons and oral and maxillofacial surgeons, there were differences in the evaluations of three variables, when the oral and maxillofacial surgeons were more critical.
Introdução: A fissura orofacial (FO) não sindrômica é o quarto defeito congênito mais frequente, além de ser a malformação craniofacial mais ocorrente. A cirurgia primária de reparação da fissura, do lábio (queiloplastia) ou do palato (palatoplastia) deve ser mais estética e funcional possível, já que o lado estético do nariz e do lábio do fissurado tem valor que vai muito além da vaidade humana, sendo primordial na formação da personalidade da criança. Objetivo: O objetivo deste estudo é comparar os resultados estéticos da queiloplastia em indivíduos com fissura labial unilateral comparando dois materiais diferentes para síntese cutânea. Casuística e métodos: Foi realizado um ensaio clínico cego controlado com distribuição aleatória na Sociedade Especializada em Atendimento ao Fissurado do Estado de Sergipe (SEAFESE). Participaram desta pesquisa todos os indivíduos que foram submetidos à queiloplastia na SEAFESE entre outubro de 2014 a junho de 2017, constituindo uma população de 50 indivíduos. O grupo controle teve como material de síntese cutânea o fio reabsorvível de poliglactina 910 e o grupo experimental, o adesivo tecidual octil-2- cianoacrilato. Esses indivíduos foram avaliados por seis avaliadores cegos, com um mês e seis meses de pós-cirúrgico, quando foram tomadas fotografias frontais padronizadas da face. A avaliação da face foi realizada utilizando a Escala Visual Analógica (EVA), a Escala Cosmética de Avaliação de Singer e a Escala de classificação proposta por Mortier. Além disso, foi realizada a análise antropométrica de Pietruski. Resultados: O perfil sociodemográfico da população estudada é de um indivíduo com idade média de 3,2 anos e com renda mensal familiar abaixo de dois salários mínimos. A maioria é natural do interior do estado de Sergipe e possui fissura pré-forame incisivo. Quanto aos resultados estéticos da queiloplastia, no segmento de um mês de pós-operatório, não houve diferença estatística significativa para a EVA e para a Escala de Mortier. Mas na Escala de Singer, o adesivo tecidual apresentou melhores resultados para as variáveis nível adjacente à pele, cor, marcas de sutura e na aparência geral. No segmento de seis meses de pós-operatório, também não houve diferença estatística significativa para a EVA. Mas houve diferença para a Escala de Singer (largura máxima da cicatriz, cor e marcas de sutura) e na Escala de Mortier (cicatriz e vermelhão do lábio superior), quando foram notados melhores resultados cosméticos com o uso do adesivo. Na análise antropométrica de Pietruski, quando os dois materiais de síntese cutânea foram comparados, observou-se diferença estatística significativa em três dos dezenove parâmetros avaliados. Por fim, quanto às complicações pós-operatórias, houve apenas uma deiscência parcial da ferida cirúrgica, no grupo controle. Conclusões: Os adesivos teciduais apresentaram um resultado cosmético superior às suturas reabsorvíveis. Na avaliação de 6 meses, o adesivo apresentou resultados superiores na análise antropométrica de Pietruski e nas escalas de Singer e Mortier. Na comparação entre cirurgiões plásticos e cirurgiões bucomaxilofaciais, houve diferença na avaliação de três variáveis, sendo os cirurgiões bucomaxilofaciais mais exigentes.

Abstract:
AbstractMechanotherapy of postoperative scarring is considered an effective measure to prevent pathological scars. Tension increases suture line enlargement, opening the way to infection. Several options have been proposed since decades and are currently used in practice, from adhesive sutures to adhesive dressings, reapproximation devices, and postoperative negative pressure. Closed incision negative pressure therapy (ciNPT) was recently proposed in at-risk patients, showing a significant difference in prevention of infection. These technologies offer a double effect of mechanical stabilization and aspiration of exudates and have recently been extended to different clinical indications. This chapter describes the recently developed technologies to diminish scar enlargement on a suture line and to prevent infection after extensive surgical procedures in thoracic, abdominal, plastic and orthopedic surgery.

Abstract:
Background Surgical knots are one of several structures which can fail during surgical repair. However, there is no universal agreement on the superiority (best/safest) of one particular surgical knot technique. Tensile testing of repaired soft tissue has been used to assess the efficacy of surgical knot tying techniques, however, few computational models exist. The purpose of this study was to create a validated biomechanical model to evaluate the effect of knot configuration on the mechanical performance of surgical sutures. Methods Two sutures were tested experimentally to find the mechanical properties and strength. Single throw knots were also tested for strength. Finite element models were constructed of each configuration and correlation was established. Results The finite element results are quantitatively and qualitatively consistent with experimental findings. The FE model stress concentrations are also consistent with published strength reductions. Model and experimental results are presented using as-manufactured No. 2 FiberWire as well as its core and jacket constituents separately. Clinical Relevance This paper describes a model which can evaluate the effect of knot topology on the mechanics of surgical suture. In the future, the model may be used to evaluate the mechanical differences between surgical techniques and suture materials. The findings may impact choices for suture and knot types selected for soft tissue repairs.

Abstract:
Background: Knot tying is considered a basic surgical skill, however, there is no consensus on the best technique. Suture breakage and slippage are failure modes during surgical repair and are related to stress concentrations which cannot be easily established with physical testing. Few computational models exist that describe the effect of knot topology on the failure mechanism. The purpose of this study was to implement the finite element method to analyze the mechanical behavior of surgical sutures according to number of throws and to validate the model against experiments. Methods: Experiments and models of monofilament and multifilament sutures were conducted. Multiple throw knots were tested to failure in a laboratory setting and with corresponding finite element models. Gross loads were compared when the knot reached a localized material yield stress in the model or when failure occurred in laboratory tests that have the same suture topology. Results: The results of laboratory tests and corresponding finite element models of single throw knots were compared and found to be well correlated and consistent with existing literature in strength prediction and failure location. Moreover, single throw knots have reduced failure strengths relative to non-knotted suture approximately by 120 N for both monofilament and multifilament sutures, respectively. Clinical Relevance: This paper describes a model which can describe the initial failure process leading to knot failure. In addition, the model can evaluate the effect of knot topology on the mechanics of surgical suture. Numerically, no assessment has been completed of knot security (i.e., how likely the knot is to untie), therefore, clinical recommendations are premature. In the future, the results may provide a framework for choosing the suture and knot types for soft tissue repairs.

Abstract:
The digital flexor tendons of the hand, including the flexor digitorum profundus (FDP), are responsible for enabling finger flexion and gripping. Injuries involving a partial or complete laceration to the digital flexor tendons are common and associated with a high incidence of morbidity [1]. The current state of the art for flexor tendon repair is the use of two or more core sutures in combination with an epitendinous circumferential suture. There are inherent limitations to suture based methods, including a high level of skill required to perform the suture repair, increased surgical time and the tendency for sutures to strangulate the tissue (creating local tissue ischemia). Suture based repairs often result in sub-optimal clinical outcomes, with reported failure rates ranging from 4%–10% [2]. In order to address these limitations, a novel non-suture based repair device has been developed. The objectives of this study were twofold. The first objective was to determine the gapping strength of the device in cadaver FDP tendons so that comparisons could be made to values reported in the literature for suture based repairs. The second objective was to determine the in-vivo capability of the device to facilitate tendon repair, relative to a suture control, in a rabbit model at a five week time point.

Abstract:
Conventional surgical suture is mechanically limited by the ability of the suture to transfer load to tissue at suture anchor points. Sutures coated with adhesives can improve mechanical load transfer beyond the range of performance of existing suture methods, thereby strengthening orthopaedic repairs and decreasing the risk of failure. The mechanical properties of suitable adhesives were identified using a shear lag model. Examination of the design space for an optimal adhesive demonstrated requirements for strong adhesion and low stiffness to maximize strength. As a proof of concept, cyanoacrylate-coated sutures were used to perform a clinically relevant flexor digitorum profundus tendon repair in cadaver tissue. Even with this non-ideal adhesive, the maximum load resisted by repaired cadaveric canine flexor tendon increased by ∼ 17.0% compared to standard repairs without adhesive. To rapidly assess adhesive binding to tendon, we additionally developed a lap shear test method using bovine deep digital flexor tendons as the adherends. Further study is needed to develop a strongly adherent, compliant adhesive within the optimal design space described by the model.

Abstract:
Abstract The design of an intracorpeal suturing device that will assist surgeons in placing an internal suture through a small incision. Performing surgical procedures through a small incision greatly reduces patient trauma and rehabilitation time, both of which are proportionally related to medical costs. Medical devices exists today that allow surgeons to perform procedures through small incisions, unfortunately, it is difficult to place sutures deep in the body using minimally invasive techniques. A device that enables surgeons to place sutures minimally invasively will facilitate surgeons by increasing the scope of procedures that can be preformed using this technique.

Abstract:
Complete removal of the meniscus (meniscectomy) often leads to early-onset of osteoarthritis due to changes in contact mechanics 1,2. To counteract these changes, the removed meniscus is often replaced with an allograft. Many variables can affect the surgical outcome of meniscal transplantation (bone geometry, graft size, fixation technique, level of activity, limb alignment, etc.) 3,4,5. Among them, the method of fixation is the most readily controlled. Two commonly used techniques are: (i) trans-osseous suture fixation via bone plugs, where bone plugs are machined at the anterior and posterior horns of the graft and implanted into appropriately sized tibial bone tunnels, and (ii) suture fixation at the meniscal horns, where the sutures are drawn through tibial bone tunnels and tied over a bone-bridge. But the mechanical consequences of these fixation techniques, specifically, how they affect knee mechanics are unclear.
