Abstract:

On distingue trois catégories d’interventions en chirurgie bariatrique les techniques restrictives, comme l’anneau gastrique ajustable (AGA) ou la gastroplastie verticale calibrée (GVC), réduisent la capacité de l’estomac et freinent mécaniquement le passage du bol alimentaire, – les techniques mal absorptives pures, qui sont abandonnées en raison du risque de carences gravissimes,- les techniques mixtes, comme le court circuit gastrique (CCG) ou la gastrectomie en manchon (GM) ; elles associent restriction et mal digestion, provocant des modifications des sécrétions hormonales digestives induisant des effets satiétogène et anorexigène. L’existence d’une hyperphagie boulimique (HB) est un facteur de risque de reprise pondérale quel que soit le type d’intervention [3]. En raison d’une morbi-mortalité post-opératoire immédiate quasi nulle, l’AGA reste très pratiqué en France. les résultats à dix ans retrouvent pour certain un taux d’échec de 50 % [2], lié à des complications, favorisées par l’HB, nécessitant une conversion de technique chirurgicale. Parmi les 196 patients opérés d’une GCV entre 1994 et 2005 à Nancy, 50 % présentaient une HB. Malgré une psychothérapie préopératoire, le taux d’échec à dix ans était de 20 %, dû à la récidive d’HB responsable de complications, nécessitant une réintervention. Parmi les techniques mixtes, le taux d’échec de la GM à cinq ans varie de 15 à 25 %, en partie lié à une dilatation du tube gastrique, favorisée par l’HB, nécessitant une réintervention. Après CCG, en cas de reprise pondérale liée à une récidive de l’HB, dans la majorité des cas, la prise en charge psychothérapeutique permet de retrouver l’efficacité du montage chirurgical sans réopérer, contrairement à la GM ou aux techniques restrictives devenues contre indiquées pour nous en cas d’HB [1]. Le rôle du psychiatre au sein de l’équipe multidisciplinaire de chirurgie bariatrique est essentiel pour le choix de la technique opératoire et maintenir son efficacité au long court.

Abstract:

Le propos de cet article est d’étudier les mutations anthropologiques générées par le passage à « la langue de l’autre ». En choisissant un corpus formé par les auteurs d’Europe médiane, notre article tente de montrer que ce passage n’est pas une simple traduction des œuvres mais consiste bien plus en une refonte identitaire des auteurs. Leur passage au français amène ces auteurs à se situer dans le courant de la littérature migrante, une littérature de l’entre-deux. Cette littérature oscillant entre un style français et un esprit d’Europe médiane conduit ces auteurs à produire des œuvres « absolument européennes ». Notre propos a pour but de poser les bases d’une différenciation entre cette francophonie et la francophonie dite « classique » afin d’ouvrir un dialogue entre celles-ci.

Abstract:

Background During fiberoptic tracheal intubation, passage of the fiberscope itself to the trachea is often fairly easy, but passage of the tube into the trachea may be difficult or even impossible. A new type of disposable endotracheal tube, the Parker Flex-Tip tube, has a tip that reduces the gap between the fiberscope and the inside of the tube. Thus, theoretically, a smaller risk of impinging on laryngeal structures during insertion in trachea is expected. Methods Eighty patients scheduled for elective anesthesia using orotracheal intubation were randomized to either a Parker Flex-Tip tube or a standard (Portex) 7.5-mm-ID endotracheal tube. Blinding was obtained by having the tube premounted on the fiberscope (Olympus LF-1; diameter of fiberscope = 4 mm) and thereafter covered with a black opaque plastic bag. Difficulty in placing the tube was scored using an objective standardized grading system. Results Seventy-six patients completed the study. The use of the Parker Flex-Tip tube reduced the incidence of need for repositioning of the tube during insertion into trachea from 89% to 29% (P < 0.0001) when compared to the standard tube. The median time for passage of the tube into the trachea was reduced from 20 s to 7.5 s (P < 0.0001). Conclusions During oral fiberoptic intubation, the use of the Parker Flex-Tip tube is associated with greater incidence of initial success of passage of the tube into trachea when compared to a standard endotracheal tube.

Abstract:

Background Insertion of a gastric tube (GT) in anesthetized, paralyzed, and intubated patients can be difficult The purpose of this study was to determine fiberoptically why GTs succeed or fail to enter the esophagus and, based on these findings, to determine a mechanism for converting failures into successes. Methods Sixty patients under general anesthesia and orotracheally intubated were studied. The larynx and hypopharynx of each patient were viewed via a fiberscope placed through the left naris. GTs were passed orally (OGT) and nasally (NGT) in all patients, and the pathway of passage or site of resistance was visualized. In cases of resistance, medially directed ipsilateral neck pressure was applied over the lateral thyrohyoid membrane (termed lateral neck pressure) to try to allow passage of the GT. Results All 60 patients had both an OGT and NGT passed for a total of 120 attempts. The GT passed easily on the first attempt in 92 of 120 insertions (77%) (for OGT 51/60 = 85% and for NGT 41/60 = 68%, P < 0.05). In 92% of these first-pass successes, the GT entered the hypopharynx just lateral to the arytenoid cartilages. The GT met resistance and failed to pass in 28 of 120 insertions (23%) (for OGT 9/60 = 15% and for NGT 19/60 = 32%). The sites of impaction were the piriform sinuses (13/28 = 46%), arytenoid cartilages (7/28 = 25%), and trachea (6/28 = 21%), and two OGTs did not pass the oropharynx (2/28 = 70%). Lateral neck pressure was attempted 20 times (for the piriform sinus and arytenoid cartilage impactions) with 17 successes (85%) and three failures (15%). The average distance to passage of the OGT and NGT by the arytenoid cartilage was 13.2 and 16.2 cm, respectively. Conclusion GTs enter the hypopharynx just lateral to the arytenoid cartilages. Consequently, the most common sites of resistance at the laryngeal level are the arytenoid cartilages and piriform sinuses. Lateral neck pressure compresses the piriform sinuses and moves the arytenoid cartilages medially, relieving 85% of these GT impactions.

Abstract:

Canalicular blockage of the lacrimal system still remains a major challenge for oculoplastic surgeons. The conventional treatment of conjunctival dacryocystorhinostomy using the Lester Jones bypass tube is often associated with tube migration and foreign body reaction. The authors report a new technique to reconstruct the lacrimal passage on a single patient with severe canalicular obstruction following repeated failures from previous Lester Jones tube operations. An epithelial-lined tube was recreated between the nasal cavity and the conjunctiva using a superiorly based mucoperichondrial flap from the nasal septum (Ipswich lacrimal tube). The pedicle of the flap was divided six weeks following the operation. The patient was still symptom free two years following the operation together with a positive dye test confirming the patency of the new lacrimal tube.

AbstractOBJECTIVE. The purpose of this paper is to describe a simple and safer silicone tube insertion technique in endoscopic dacryocystorhinostomy.MATERIAL AND METHODS. In our technique, steel wire is inserted into a rigid suction tube (3 mm in diameter) immediately after the medial wall of the sac under endoscopic view. The duration of retrieving the wire from the sac and out of the nasal passage, the number of mucosal lacerations and bleeding were compared with conventional methods such as using retrieval device or forceps.RESULTS. The duration of retrieving the wire from the sac and out of the nasal passage and mucosal laceration were statistically reduced (P<0.05) in this novel technique when compared with other methods.CONCLUSION. Sheltering the sharp end of the wire with a suction cannula is a safe and easy method without using any additional tools

Abstract:

Background/Aim. Eustachian tube is a connection between throat and the middle ear. Inflammatory processes and malformations of nasal cavity could lead to dysfunction of the whole upper respiratory tract, this emphasizing the evaluation of the Eustachian tube function both in surgery and in medicine in general. The aim of this study was to evaluate the Eustachian tube passage and function by tympanometry in different types of nasal resistance. Methods. Eustachian tube passage and function was tested in 102 patients with different types of nasal pathology and nasal resistance and compared to the results of 41 healthy persons with normal values of nasal resistance included in the control group. The patients with nasal pathology were divided into three subgroups: with mechanical, inflammatory and mixed alterations. Nasal resistance was carried out with constant body plethysmography (Jaeger). The test of Eustachian tube passage and function was performed using tympanometric Toynbee-deglutition/Valsalva-deglutition test. The results of measurements were compared with those in the healthy control group and analyzed by means of parametric and nonparametric statistic tests, Pearson ?2 test, Fisher test of exact probability and variance analysis. Results. The subgroup with inflammatory alterations had significantly higher values of pathological tympanograms than other subgroups and the control group (p < 0,05). The dysfunction of the Eustachian tube was significantly more present in all subgroups than in the control group (p < 0,05). Conclusion. Pathological form of tympanograms is more often present in purely inflammatory changes of nasal cavities with higher nasal resistance than in mechanical nasal obstruction. All forms of higher nasal resistance are more often accompanied with Eustachian tube dysfunction. There was no significant differences in Eustachian tube passage between the subgroups and the control group.

Abstract:

The ellipsoidal generative cell of the pollen grain of Endymion nonscriptus usually elongates further following germination and entry into the tube, producing attenuated extensions the forward one of which may reach into the vicinity of the vegetative nucleus. This shape change is accompanied by the stretching of the microtubule cytoskeleton of the cell, identified in the present work by immunofluorescence using monoclonal antibodies to tubulin. Complementary observations of living generative cells of Iris pseudacorus showed that they undergo slow undulatory movements accompanied by variation in shape and length during passage through the tube. Such changes must presumably be accompanied by modifications of the microtubule cytoskeleton. Colchicine at 1 mM eliminated microtubules from tubes and most generative cells of E. nonscriptus, but did not radically affect pollen-tube shape or extension growth, nor arrest the movements of the vegetative nucleus and generative cell into and through the tube. Generative cells in colchicinetreated pollen of Galanthus nivalis rounded up and failed to undergo the usual changes in shape during passage through the tube. Secondary consequences were changes in precedence in movement through the tube, and a greater dispersal along its length. On the assumption that no other cytoskeletal elements remain to be discovered, it seems likely that microfilaments rather than microtubules provide the motive force for movement in the tube, although the latter are involved in shaping the generative cell and adapting it to its passage.

Abstract:

Background The design of an endotracheal tube has been shown to influence the passage of the tube through the glottis during fiberoptic intubation. Difficulty in passing the endotracheal tube can occur if the aryepiglottic folds obstruct the passage of the bevel. The relevant aspects of endotracheal tube design include the shape of the bevel, the material used by the manufacturer, and the ability of the tube to conform to the shape of the fiberscope. The aim of the current study was to compare the ease of passage through the glottis of two different tubes. One tube was a wire reinforced polyvinyl chloride tube with a standard bevel and the other was a newly designed tube with a bevel of different shape and made of silicone rubber. The new design is for use with the a commerical intubating laryngeal mask. Methods The authors studied a population of 30 patients who received a standard anesthetic. In all cases, oral fiberoptic intubation was attempted. Anesthetic was administered to each patient using both tubes, and before the study the order of the tubes was randomized. The difficulty in passing the tube was assessed by a blinded observer and graded using a three-point scale (grade 1: no difficulty passing the tube; grade 2: obstruction to passing the tube relieved by withdrawal and a 90 degrees anticlockwise rotation; grade 3: obstruction necessitating more than one manipulation or external laryngeal manipulation). Results In 27 patients, no difficulty was shown by use of the silicone-tipped tube. In only three patients was there difficulty that necessitated a 90 degrees anticlockwise twist. With the wire-reinforced tube, no difficulty was experienced on 14 occasions. Grade 1 difficulty was experienced eight times and difficulty necessitating more than one maneuver, head movement, or external laryngeal manipulation was seen on eight occasions. Statistical significance was achieved at P = 0.0002 (Wilcoxon signed rank test). Conclusions The authors conclude that the use of the silicone-tipped tube with the new bevel design may provide an advantage in the clinical situation of fiberoptic intubation.

La systématisation du contenu et des fonctions de la notion d’économie du contrat en droit français a abouti au postulat d’une théorie dite de l’économie du contrat. Dans son article, l’auteur tente d’en poser les jalons en dépassant l’approche dogmatique adoptée jusqu’ici par la doctrine française et belge. Il expose ainsi une nouvelle approche qui marque le passage de la notion à la théorie de l’économie du contrat en tant que théorie réaliste d’interprétation prenant en considération l’esprit général des clauses et la concrétisation de la volonté commune des parties d’après l’équilibre et la finalité de l’opération contractuelle. Cette théorie véhicule l’idée d’un contrat-opération qui se situe dans une perspective interdisciplinaire de l’analyse du phénomène contractuel, à contre-courant du modèle du contrat-obligation du Code Napoléon et du Code civil du Québec.

Abstract:

Shield construction will cause surface subsidence, and the presence of underground structures above the tunnel has an impact on surface subsidence. Based on this, with the engineering of undercross shield tunnel construction on railway station as background, used numerical simulation method to analyze the effect of surface subsidence of underground passage, and studied the influence of depth and width of underpasses on ground movement induced. The results show that: The impact of the underground passage to the wire surface subsidence caused by the shield cannot be ignored. Surface subsidence caused by double shield will be decreased because of the existence of the underground passage, and that related to the channel depth and width. The greater the depth of underground channel, the greater the surface subsidence; greater the underground channel width, the smaller surface subsidence. Meanwhile, the surface subsidence trough width and the largest settlement scope unrelated to the depth of underground tunnels but the underground channel width, and increases with the increasing of the underpass width.

Abstract:

We applied transient positioning of a silicone T tube in 18 patients with frontal sinus cysts. Inflammation in the nasal cavity usually subsided within 6 months of surgery, whereas the frontal sinus showed pathologic changes in more than half of the patients even 6 months after surgery. After removal of the tube, the nasofrontal passage remained open in 16 patients who obtained good aeration with an intact mucosal lining in the frontal sinus, but it eventually closed in the remaining 2 patients who failed to obtain good aeration. This finding suggests that persistent inflammation in the frontal sinus encourages the closure of the nasofrontal passage and that transient positioning of a silicone T tube is successful if it is removed after subsidence of inflammation in the sinonasal tract.

Abstract:

The objective of the Innovative High-Temperature Aircraft Engine Fuel Nozzle Program was to design and evaluate a nozzle capable of operating at a combustor inlet air temperature of 1600°F (1144 K) and a fuel temperature of 350°F (450 K). The nozzle was designed to meet the same performance requirements and fit within the size envelope of a current production F404 dual orifice fuel nozzle. The design approach was to use improved thermal protection and fuel passage geometry in combination with fuel passage surface treatment to minimize coking at these extreme fuel and air temperatures. Heat transfer models of several fuel injector concepts were used to optimize the thermal protection, while a series of sample tube coking tests were run to evaluate the effect of surface finish, coatings, and tube material on the coking rate. Based on heat transfer analysis, additional air gaps, reduced fuel passage flow area, and ceramic tip components reduced local fuel wetted wall temperatures by more than 200°F (110 K) when compared to a current production F404 fuel nozzle. Sample tube coking test results showed the importance of surface finish on the fuel coking rate. Therefore, a 1 μin. (0.025 μm) roughness was specified for all fuel passage surfaces. A novel flow divider valve in the tip was also employed to reduce weight, allow room for additional thermal protection, and provide back pressure to reduce the risk of fuel vaporization. Phase II of this program will evaluate the fuel nozzle with a series of contaminated fuel and coking tests.

Abstract:

This preliminary investigation studied the effect of circular turbulator vortex generator on heat transfer rate and pressure drop in a circular channel countercurrent double pipe heat exchanger with water working fluid. Increasing the number of circular turbulator yielded increasing heat transfer rate and pressure drop. The problem generated when increased pressure drop occurred in relation to more energy consumption of the water pumping system. Therefore, optimization in circular turbulator number is necessary to minimize the pressure drop about distance length between circular turbulator, tube diameter and thickness, type of material and crystal lattice, as well as the geometrical shape of fluid passage (circular or square). This study applied PVC outer tube and copper alloy inner tube, as well as fiberglass circular turbulator. The optimum results showed that seven parts of circular turbulator increasing heat transfer rate by 30% and pressure drop by 80% compared to that passage in the absence of circular turbulator at cool water debit of 7 L/min.

Abstract:

We present a case of a 30-year-old female, who had tracheostomy revision complicated by false passage into the subcutaneous space and pneumothorax. Six days later, she developed massive bleeding from the mouth, nose, and tracheostomy site. Approximately 2 liters of blood was lost. With high suspicion for tracheo-innominate fistula, she was emergently brought to the operating room for fistula repair. Her anesthetic management was initially focused on maintaining spontaneous ventilation with inhalation agents until surgical exposure was adequate. An endotracheal tube was then placed under guidance of a video-laryngoscope. The tracheostomy tube was then removed over a Cook catheter to maintain secure passage in case of airway collapse. The oral endotracheal tube was then inserted distal to the arterial and tracheal defect. The patient’s bleeding was stopped, the fistula was repaired, and she was transferred back to the intensive care unit, but she died several days later due to multi-organ failure.

Abstract:

This case report describes an alternative method of achieving trans-oral intubation in a patient with a difficult airway who was apnoeic secondary to the therapeutic administration of a non-depolarizing neuromuscular blocking drug given to aid laryngoscopy. After attempts to intubate were unsuccessful by means of direct laryngoscopy utilizing various aids including bougies, a standard laryngeal mask airway was used to ventilate the patient and subsequently, with a swivel Y-connector attached in order to maintain PEEP, to aid the passage of a bronchoscope. The flexible guide-wire from an enteral feeding tube was then passed through the suction port of the bronchoscope into the trachea, after which the laryngeal mask airway and bronchoscope were withdrawn. By passing the enteral feeding tube over the guide-wire and then using this as a guide, a cuffed endotracheal tube was inserted into the trachea. The technique described permitted the continuous application of positive airway pressure, which dramatically improved the bronchoscopic view during the crucial step of placing the guide-wire into the trachea. Passing the feeding tube over the guide-wire aided the subsequent passage of the endotracheal tube, by acting as a stiffer and larger diameter guide through the glottis.

Abstract:

The complication of intracranial placement of a nasogastric tube in patients with complex facial and skull base fractures is rarely seen. A case report of a patient with complex craniofacial injury after trauma in whom a computerized tomogram scan showed passage of a nasogastric tube via a fracture of the anterior cranial fossa floor into the skull vault is presented. This case stresses the caution to be exercised in the emergency room resusitation of patients with craniofacial injury requiring nasogastric tube placement.

Abstract:

One-lung ventilation can be achieved with a double-lumen tube or a bronchial blocker. However, the larger outer diameters of double-lumen or Univent tubes may prevent their passage through an area of subglottic stenosiss. We present five cases of subglottic stenosis in which a Fogarty catheter was used as a bronchial blocker through a single-lumen endotracheal tube. The outer diameters of a double-lumen tube, Univent tube and single-lumen tube were compared. Despite special equipment designed for one-lung ventilation, the use of a bronchial blocker through a single-lumen tube, which has the thinnest available wall thickness, seems to be one of the most effective and safest ways of achieving one-lung ventilation in patients with subglottic stenosis or narrowing.

Abstract:

In this paper presents the study of the process of interaction between helium (He) and methane (СH4) molecules and the energy barrier created by a single-layer carbon nanotube. The interaction potential fields for the case of a tube as a nano-scale object interacting with single molecules or atoms were determined. Calculations show the dependence of molecular velocity within the symmetry axis of a single-layer carbon nanotube on the axial coordinate. The influence of the tube radius on the character of molecular passage through the open tube is considered.

Abstract:

This paper proposes a novel-type of “double-walled” reactor tube with molten-salt thermal storage at high temperatures for use in solar tubular reformers. The prototype reactor tube is demonstrated on the heat-discharge and chemical reaction performances during cooling mode of the reactor tube at laboratory scale. The Na2CO3 composite material with MgO ceramics was filled into the outer annulus of the double-walled reactor tube while the Ru-based catalyst particles were filled into the inner tube. The heat discharge form the molten Na2CO3 circumvented the rapid temperature change of the catalyst bed, which resulted in the alleviation of decrease in chemical conversion during cooling mode of the reactor tube. The application of the new reactor tubes to solar tubular reformers is expected to help realize stable operation of the solar reforming process under fluctuating insolation during a cloud passage.

Abstract:

Chronic eustachian tube dysfunction contributes to many chronic middle ear diseases and to early and late surgical failures. Furthermore, surgeons may overlook air passage obstructions from the mesotympanum to the mastoid cavity. To date, long-term ventilation of the middle ear is the most practical technique of bypassing stubborn eustachian tube and middle ear ventilatory malfunctions. I present the techniques used to overcome and bypass tubal and intratympanic obstructions in 8% of operated ears in the past 6 years.

Abstract:

Abstract: The paper aimed at a detailed case study of cross-passage, which is forced to design and construct by connecting the station box and main tube tunnel of Marol Naka station in Mumbai Metro Line 3, since the marol Naka is densely populated area and elevated metro line is passing over an underground station, therefore further excavation of tunnel is done through the cross-passage. In these station, the cross- passage is constructed for public utilities for connecting the station box to the platform and also for the emergency exit. During tunnel construction, the cross passage is excavated after the main tunnel has been constructed. At the same time, the safety of the cross passage and the stability of the tunnel must be ensured by instrumentation and monitoring. Design of the cross- passage is achieved according to the principles of “New Austrian Tunnelling Method’ (NATM) and the composite lining structure is adopted. NATM is used to widen the station platform which is initially tunnelled by the TBM. The dimension of 230m long and 15m wide Marol Naka station has 16 cross-passages which are constructed connecting the station box to the platform; the observations and the designing part- Finite Element method is used in order to evaluate stress deformations induced on the cross-passage. Keywords: Cross passage, NATM, TBM, Finite element method, Marol Naka station, Emergency exit.

Abstract:

Background: Nasogastric (NG) decompression and delayed oral feeding after bowel anastomosis is conventional and years old practice. The aim of the present study was to evaluate the advantages and disadvantages of early removal of naso gastric tube (<24 hrs) and delayed feeding, compared with delayed removal and delayed enteral feeding in patients undergoing bowel anastomosis.Methods: It is a single blind, prospective randomized study involving patients with bowel anastomosis from December 2016- November 2018 at a tertiary care hospital. In study group naso gastric tube was removed within 24 hours. After 12 hours of surgery patients were allowed sips of water, then free liquids followed by semisolid and normal diet in calculated way. In control group naso gastric tube was retained till passage of flatus and orally allowed only after passage of stool.Results: A total of 241 patients were enrolled. In study group bowel sound returned after 30.57±31.19 hours of surgery and in control group 46.90±48.65 hours and this difference was significant (p<0.002). In study group first free liquid was allowed on 38.14±38.50 hours in post operative period, as compared to the control group where free liquids were allowed after 50.09±51.80 hours this difference was significant (p<0.04). Total hospital stay in the study group was significant (p<0.02).Conclusions: Early removal of naso gastric tube and early feeding is better than the conventional practice.

Abstract:

Background: Although up to 90% of patients experienced full recovery following long-tube decompression, without the need for surgical intervention, the remaining patients do not yield any benefit from the use of long nasointestinal tubes and require surgical intervention. Aim: To introduce an improved transnasal ileus tube technique for intractable adhesive small bowel obstruction (ASBO), and evaluated its efficacy in the management of intractable ASBO. Methods: 54 patients with intractable ASBO were treated with the improved transnasal ileus tube technique. The obstructions were passed through by balloon relay, and the adhesions were resolved by repeated to-and-fro movements of the ileus tube. Enterographic results were categorized as complete or incomplete resolution of the obstructions. Data on the technical success, final enterographic results, mortality, morbidity, and the final clinical outcome were collected, and follow up was performed at 1, 3, 6, and 12 months, and then yearly after the procedure. Results: Transnasal ileus tube placement was successful in all patients. Navigation and passage of the ileus tube through the obstructions to the colon were successful in 87% of the attempted tubes (47/54) and failure in 7 patients (4 patients due to severe obstruction and 3 patients due to the presence of a true stricture in the small bowel). Follow-up enterograms over 3-38 months indicated smooth passage of the contrast medium through the small bowel, without any difficulty, in 48 patients. Full recovery from ASBO was achieved in 48 patients (mean duration, 20.16 ± 10.04 months; range, 6-45 months). Six patients died of multiple organ failure without recurrent ASBO, and the clinical symptoms of small bowel obstruction recurred 2 patients. Conclusion: The improved transnasal ileus tube technique is a novel, safe, and effective technique that enables intractable ASBO resolution.

Abstract:

Using the acoustic input impedance, an appropriate theoretical technique for identifying constrictions in a tube with wall inertance and elastance being considered is developed. Although the technique could work for various types of tubes, it is applied to identifying occlusion in an upper airway passage. The frequency spectrum of the input impedance is examined for three types of constrictions, namely localized, uniform and gradual models. The result demonstrates that the input impedance resonant frequencies can map the location, severity and degree of the constriction.
