Abstract:
Spinal endoscopy has evolved significantly since its inception, offering minimally invasive solutions for various spinal pathologies. This study introduces a promising innovation in spinal endoscopy—a single-use digital endoscope designed to overcome the drawbacks of traditional optic endoscopes. Traditional endoscopes, despite their utility, present challenges such as fragility, complex disinfection processes, weight issues, and susceptibility to mechanical malfunctions. The digital endoscope, with its disposable nature, lighter weight, and improved image quality, aims to enhance surgical procedures and patient safety. The digital endoscope system comprises a 30-degree 1000 × 1000 pixel resolution camera sensor with a 4.3 mm working channel, and LED light sources replacing optical fibers. The all-in-one touch screen tablet serves as the host computer, providing portability and simplified operation. Image comparisons between the digital and optic endoscopes revealed advantages in the form of increased field of view, lesser distortion, greater close-range resolution, and enhanced luminance. The single-use digital endoscope demonstrates great potential for revolutionizing spine endoscopic surgeries, offering convenience, safety, and superior imaging capabilities compared to traditional optic endoscopes.

Abstract:
AbstractBackgroundThree-dimensional endoscopes provide a stereoscopic view of the operating field, facilitating depth perception compared to two-dimensional systems, but are not yet widely accepted. Existing research addresses performance and preference, but there are no studies that quantify anatomical orientation in endoscopic ear surgery.MethodsParticipants (n = 70) were randomised in starting with either the two-dimensional or three-dimensional endoscope system to perform one of two tasks: anatomical orientation using a labelled three-dimensional printed silicone model of the middle ear, or simulated endoscopic skills. Scores and time to task completion were recorded, as well as self-reported difficulty, confidence and preference.ResultsNovice surgeons scored significantly higher in a test of anatomical orientation using three-dimensional compared to two-dimensional endoscopy (p < 0.001), with no significant difference in the speed of simulated endoscopic skills task completion. For both tasks, there was lower self-reported difficulty and increased confidence when using the three-dimensional endoscope. Participants preferred three-dimensional over two-dimensional endoscopy for both tasks.ConclusionThe findings demonstrate the superiority of three-dimensional endoscopy in anatomical orientation, specific to endoscopic ear surgery, with statistically indistinguishable performance in a skills task using a simulated trainer.

Abstract:
Abstract Background and study aims The current practice of endoscopists is undergoing a dramatic revolution due to emerging endoscopy practices. Increasing use of gastrointestinal endoscopy has led to hospital budgets setting aside funds specifically related to damage to endoscopic instruments. Therefore, training in understanding endoscopic equipment, handling techniques, and equipment care can be helpful in addressing this issue. The aim of this study was to investigate the effects of educational courses and training about basic endoscopic handling and care in gastrointestinal endoscopic care and services. Methods A number of new endoscopists, nurses, and nurse assistants were enrolled in a course for training in basic endoscopic handling and care. Data on the type of damage, cause, cost, and timing of endoscopic repair were prospectively collected. Data from the post-training period then were compared with retrospective data from the pre-training period. Results This study demonstrated that after training, there was less damage to endoscopes, lower costs associated with it, and repair times were shorter for endoscopes than before the training course. Post-training results indicated savings of a total of $ 40,617.21 or £ 29,539.78 and 102.6 days per damaged endoscope. Conclusions Basic endoscopic handling and care training plays an important role for both endoscopists and nurses, as well as in endoscopy facilities, specifically in avoiding the nuisance of unwanted and broken endoscopes. This could be beneficial for both hospital finances and endoscopic services.

Abstract:
Background: Image-enhanced endoscopy methods such as narrow-band imaging (NBI) are advantageous over white-light imaging (WLI) for detecting gastric atrophy, intestinal metaplasia, and cancer. Although new third-generation high-vision ultrathin endoscopes improve image quality and resolution over second-generation endoscopes, it is unclear whether the former also enhances color differences surrounding atrophy and intestinal metaplasia for endoscopic detection. We compared the efficacy of a new third-generation ultrathin endoscope and an older second-generation endoscope. Methods: We enrolled 50 Helicobacter pylori-eradicated patients who underwent transnasal endoscopy with a second-generation and third-generation endoscope (GIF-290N and GIF-1200N, respectively) in our retrospective study. Color differences based on the International Commission on Illumination 1976 (L*, a*, b*) color space were compared between second-generation and third-generation high-vision endoscopes. Results: Color differences surrounding atrophy produced by NBI on the GIF-1200N endoscope were significantly greater than those on GIF-290N (19.2 ± 8.5 vs. 14.4 ± 6.2, p = 0.001). In contrast, color differences surrounding intestinal metaplasia using both WLI and NBI were similar on GIF-1200N and GIF-290N endoscopes. NBI was advantageous over WLI for detecting intestinal metaplasia on both endoscopes. Conclusions: NBI using a third-generation ultrathin endoscope produced significantly greater color differences surrounding atrophy and intestinal metaplasia in H. pylori-eradicated patients compared with WLI.

Abstract:
Lower gastrointestinal endoscopy has evolved over time, fulfilling a widening diagnostic and therapeutic remit. As our understanding of colorectal cancer and its prevention has improved, endoscopy has progressed with improved diagnostic technologies and advancing endoscopic therapies. Despite this, the fundamental design of the endoscope has remained similar since its inception. This review presents the important role lower gastrointestinal endoscopy serves in the prevention of colorectal cancer and the desirable characteristics of the endoscope that would enhance this. A brief history of the endoscope is presented. Current and future robotic endoscopic platforms, which may fulfil these desirable characteristics, are discussed. The incorporation of new technologies from allied scientific disciplines will help the endoscope fulfil its maximum potential in preventing the increasing global burden of colorectal cancer. There are a number of endoscopic platforms under development, which show significant promise.

Abstract:
Background. No consensus exists regarding which procedures should be performed to disinfect endoscopes and working platforms after COVID-19 patients have undergone endoscopy. Methods. We analyzed the disinfection quality of endoscopes and working platforms after 11 COVID-19 patients had undergone endoscopy. Conclusions. For endoscopic preprocessing at the bedside, a key disinfection step is using a multienzyme stock solution. The nucleic acid tests for endoscopists, washers, endoscopes, and working platforms were all negative. Based on our experience with the 11 COVID-19 patients who had undergone endoscopy, we provide an endoscopic reprocessing method for the bedside endoscopic diagnosis and treatment of COVID-19 patients for reference.

Abstract:
The geometric optics of an endoscope can be used to determine the absolute size of an object in an endoscopic field without knowing the actual distance from the object. This study explores the accuracy of a technique that estimates absolute object size from endoscopic images. Quantitative endoscopy involves calibrating a rigid endoscope to produce size estimates from 2 images taken with a known traveled distance between the images. The heights of 12 samples, ranging in size from 0.78 to 11.80 mm, were estimated with this calibrated endoscope. Backup distances of 5 mm and 10 mm were used for comparison. The mean percent error for all estimated measurements when compared with the actual object sizes was 1.12%. The mean errors for 5-mm and 10-mm backup distances were 0.76% and 1.65%, respectively. The mean errors for objects <2 mm and ≥2 mm were 0.94% and 1.18%, respectively. Quantitative endoscopy estimates endoscopic image size to within 5% of the actual object size. This method remains promising for quantitatively evaluating object size from endoscopic images. It does not require knowledge of the absolute distance of the endoscope from the object, rather, only the distance traveled by the endoscope between images.

Abstract:
Early diagnosis of various diseases significantly improves survival. However, more than half of these cases are diagnosed late due to the high demand for colonoscopy - the "gold standard" of screening. Colonoscopy is limited by the outdated design of conventional endoscopes due to the high complexity and cost of use. Magnetic endoscopes are a promising alternative and overcome the cost disadvantages, but their translational phase is difficult to achieve because magnetic manipulations are complex and unintuitive. In this work, we use machine vision to develop an intelligent and autonomous endoscope control that allows non-expert users to efficiently perform in vivo magnetic colonoscopy. We combine the use of robotics, computer vision, and advanced control to offer an intuitive and efficient endoscopic system. Furthermore, we define the characteristics required to achieve autonomy in robotic endoscopy. The paradigm described here can be applied to a variety of applications requiring navigation in an unstructured environment, such as catheters, pancreatic endoscopy, bronchoscopy, and gastroscopy. This work brings alternative endoscopic technologies closer to the translational stage, increasing the availability of early disease treatment.

Abstract:
In the last 20 years, there have been important developments in endoscopy. Initially, endoscopy was developed and used as a diagnostic tool. As new technology developed, these devices also became the basis for therapeutic maneuvers. In recent years, flexible endoscopes have been used to per- form procedures replacing traditional surgical approaches. Examples of this field are transanal minimally invasive surgery, natural orifice transluminal endoscopic surgery, endoscopic metabolic surgery and third space endoscopies. Throughout history, surgeons have played a vital role in the design and development of endoscopic techniques, procedures, and equipment. Surgeons continue to lead the advancement of endoscopy, make important contributions, and serve as role models for innovation.

Abstract:
The review presents the stages of the development of endoluminal endoscopy from rigid endoscopes with tube illumination to digital high-resolution endoscopy and methods of optical biopsy. The development of endoscopic studies in children began in the 60s of the XX century, and now they are indispensable methods of the visualization. There are described diagnostic options and achievements of intraluminal endoscopy in children, as well as the prospects for its development. The current level of endoscopy in pediatrics includes a high resolution of the obtained image, a morphological study of biopsies and a full range of endosurgical procedures. The authors believe the prospects for the development of endoluminal endoscopy in pediatrics to be determined by the improvement of endoscopes along with maintaining their high resolution with a gradual transition to robotic remote-controlled endoscopic systems.

A cirurgia dos tumores selares é tradicionalmente um campo de atuação dos neurocirurgiões. Contudo, desde a retomada da abordagem transeptaltransesfenoidal para acessar a sela túrcica, na década de sessenta do século passado, os otorrinolaringologistas têm exercido importante parceria neste procedimento. A divulgação da cirurgia endoscópica nasossinusal na otorrinolaringologia criou o interesse pela sua aplicação na cirurgia da região selar. a uso do endoscópio permitiu acesso transnasal direto ao seio esfenoidal sem a necessidade de descolamento do septo nasal, com menor desconforto para o paciente, além de morbidade pós-operatória inferior aos métodos tradicionais. Objetivo: O objetivo deste trabalho foi verificar as dificuldades técnicas, intercorrências e complicações pós-operatórias, no manejo otorrinolaringológico do acesso transnasal endoscópico à sela túrcica. Método: Foram analisados retrospectivamente os prontuários e imagens de arquivo de 159 pacientes submetidos à cirurgia da região selar entre março de 2001 e dezembro de 2005, na Universidade Federal de São Paulo / Escola Paulista de Medicina. Foram incluídos neste estudo 91 pacientes submetidos a um total de 95 procedimentos por via transnasal endoscópica. Resultados: Foi possível a realização da técnica endoscópica transnasal em todos os pacientes estudados, independente de idade, presença de variações anatômicas, características e etiologia do tumor, e antecedente de cirurgia prévia. Não houve necessidade de remoção da concha média ou correção de desvios septais para realização do procedimento cirúrgico em nenhum dos casos. A principal intercorrência foi a abertura do diafragma selar durante a remoção de tumores, causando fístula liquórica intra-operatória em 13,68 por cento dos casos. As complicações pós-operatórias encontradas foram: sangramento nasal (8,42 por cento), fístula liquórica (8,42 por cento), e meningite (2,19 por cento). Conclusão: O acesso endoscópico transnasal aos tumores selares pôde ser realizado de forma minimamente invasiva, preservando-se as estruturas nasais nos 95 procedimentos estudados, independente da idade do paciente, características e etiologia do tumor.
Sellar tumor surgery is traditionally a neurosurgeon´s field. However, since the renewed interest in the transseptal-transsphenoidal approach to access the sellar region in the sixties, otolarynngologists have played an important partnership in this procedure. Divulging of endoscopic sinus surgery in otolaryngology created an interest in its application in sellar region surgery. The use of endoscopes allowed a direct transnasal approach to the sphenoidal sinus without need of dissection of the septal mucosa, with less post-operative discomfort and morbidity inferior to that of traditional methods. Objective: The objective of this work was to verify the technical difficulties, intercurrences and post-operative complications in the otolaryngological handling of the endoscopic transnasal approach to the sellar region. Method: The analisys comprised both the files and archive images of 159 patients submitted to sellar region surgery between march 2001 and December 2005, at Universidade Federal de São Paulo / Escola Paulista de Medicina. 91 patients submitted to a total of 95 endoscopic transnasal procedures were included in this study. Results: It was possible to apply the endoscopic transnasal tecnique in all studied patients, independent of age, anatomical variations, tumor characteristics and etyology, and previous surgery history. There was no need of middle turbinate removal, or septal deviations corrections for the surgical procedure in any of the cases. The main intercurrence was the opening of the sellar diaphragm during the removal of the the tumors, causing intra-operative CSF leak in 13.68% of the cases. The post-operative complications encountered were: nasal bleeding (8.42%), CSF leak (8,42%), and meningitis (2.19%). Conclusion: Transnasal endoscopic approach to sellar tumors was done in a minimally invasive form, preserving the nasal structures in the 95 studied procedures, independently of patient age, tumor characteristics and etyology.

Abstract:
INTRODUÇÃO: A técnica de ESD (Endoscopic Submucosal Dissection) é um procedimento endoscópico de grande complexidade, com alto índice de complicações e dificuldades técnicas. Para superar este problema, muitos centros de treinamento em endoscopia vêm publicando a aplicabilidade dos modelos animais para a aquisição de competência em ESD. Em todas as publicações sobre o assunto, a habilidade do aluno é acompanhada pela evolução de variáveis como o tempo de ressecção, ressecção em bloco e complicações tais como sangramento e perfuração; entretanto a profundidade de ressecção nunca foi utilizada como parâmetro de aprendizagem, o que pode ser um fator relevante a ser ensinado, dado que atingir o plano de dissecção ideal é de suma importância para uma ressecção curativa e na prevenção de complicações intraoperatórias. O objetivo do estudo foi analisar o aprendizado em ESD em treinamentos de curta duração através da avaliação da profundidade de submucosa ressecada; e sua associação com complicações. MÉTODOS: estudo experimental; incluídos 25 endoscopistas com experiência em procedimentos terapêuticos ( > 5anos) e 75 peças ressecadas por ESD sendo uma média de 3 resseções por endoscopista. Os parâmetros de aprendizagem (tempo de ressecção, tamanho, taxa de ressecção em bloco, sangramento, perfuração e análise histológica da camada submucosa) foram prospectivamente avaliados. Antes, durante e ao final do treinamento os participantes foram submetidos a um questionário sobre a dificuldade e insegurança em realizar o procedimento. RESULTADOS: Todas as ressecções foram realizadas no corpo gástrico (n=75). O tamanho médio das peças ressecadas foi de 23,97 ± 7,2 mm. O número de complicações como sangramento, perfuração e morte foram respectivamente, 17 (22,67%), 3 (4%) e 0 casos. Na terceira dissecção, tempo médio do procedimento diminuiu de 28,44 ± 9,73 para 18,72 ± 8,81 minutos (p < 0,001). Quando comparada a primeira com a terceira dissecção houve uma diminuição significativa na taxa de sangramento (p=0,047) em contraste com a percentagem de submucosa ressecada que foi aumentando progressivamente quando comparada a primeira (53.5 ± 23.76%), segunda (61.8±26.47%) e terceira (69.82 ± 27.86) dissecção (p=0,073). O número de participantes que se sentiam inseguros diminuiu de 100(IC95%: 83,88-100) para 32(IC95%: 17,18-51,78), (p < 0,001). O grupo que teve sangramento durante o procedimento ressecou 37,97±21,13% da camada submucosa e o grupo sem sangramento ressecou 68,66±23,99%, demonstrando uma associação significante entre a profundidade de dissecção submucosa e a incidência de sangramento (p < 0,001). De acordo com a análise de curva ROC, o valor de corte da profundidade de submucosa ressecada para a ocorrência de sangramento é de 61%(64% sensibilidade, 94% especificidade), logo quando o ESD é realizado em uma profundidade maior do que 61% da camada submucosa o risco de sangramento durante o procedimento diminui (VPP=0,97; IC95%:0,85-0,99). CONCLUSÃO: O modelo de treinamento de curta duração possibilitou um aprendizado da técnica de ESD mostrando uma melhora cognitiva dos alunos já na terceira dissecção através de parâmetros como tempo de ressecção, diminuição dos casos de sangramento, um menor nível de insegurança e um maior percentual de submucosa ressecada comprovada na análise histológica. Existe uma associação significativa entre a profundidade de ressecção da submucosa com o risco de sangramento, ou seja, quanto mais profundo a ressecção na camada submucosa menor serão os episódios de sangramento
BACKGROUND: Endoscopic submucosal dissection is a complex endoscopic technique, with several technical difficulties to overcome and potentially high complication rates. To overcome that problem many endoscopic training centers in the west have been reporting the usefulness of animal models to achieve some expertise. In most of these reports the variables used to evaluate their learning curve are resection time, complete en-bloc resection rate and complications as bleeding and perforation; however the depth of the submucosal resection has never been analyzed. That might be a relevant factor since appropriate depth of submucosal dissection is important to a curative resection and prevent intraoperative complications which could be a very important concept to be taught during ESD training. The aim of this study is to evaluate the association between the depth of submucosal resection with the learning curve in ESD and their complications. METHODS: Twenty-five senior endoscopists with experience in therapeutic procedures ( > 5years) undergone seventy-five en bloc ESDs in live porcine models. Each participant did at least 3 endoscopic resections. The learning curve parameters (procedure time, specimen size, en-bloc resection rate, perforation, bleeding and histological analysis of the submucosal layer) were prospectively evaluated. During and after each procedure the participants were submitted into a questionnaire about difficulties and insecurities in doing this procedure. RESULTS: ESDs were all completed at the gastric body (n=75). Medium sizes of the specimens resected were 23.97 ± 7.2 mm. Complication as bleeding, perforation and death were seen respectively in 17 (22.67%), 3 (4%) and 0 cases. After the third ESD, procedure mean time has progressively reduced from 28.44 ± 9.73 to 18.72±8.81 minutes (p < 0.001). Bleeding rate were significantly lower when comparing the first to the third resection (p=0.047) and the depth of submucosal resection, in contrast, has increased when comparing the first (53.5±23.76%), second (61.8±26.47%) and third (69.82±27.86) dissection (p=0.073). Results of the questionnaire showed that participants felt increasingly less insecure from the first (95%CI: 100(83.88-100)) until the third (95%CI: 32(17.18-51.78)) ESD procedure (p < 0.001). The group that had bleeding during the procedure resected 37.97±21.13% of the submucosal layer and the non-bleeding group resected 68.66±23.99%, showing a significant association between the depth of submucosal dissection and the incidence of bleeding (p < 0.001). According to the ROC curve analysis, the resulting cutoff value of the submucosal dissection depth for bleeding is 61 %( 64% sensitivity, 94% specificity). When ESD is done deeper than 61% of the submucosal layer the risk of bleeding decreases during the procedure (PPV=0.97, 95%CI: 0.85-0.99). CONCLUSION: The short term ESD training course in live porcine models made a significant improvement on ESD skills regarding on resection time, bleeding rate, insecurity and increased depth of submucosal resection. Association between the depths of submucosal resection with the incidence of bleeding might be significant, which means that deeper in the submucosal layer undergoes the procedure; lower will be the risk of bleeding

Abstract:
Introduction: Oesophagogastroduodenoscopy is the investigation of choice to identify mucosal lesions of the upper gastrointestinal tract, but it is poorly tolerated by patients. A simple non-invasive technique to image the upper gastrointestinal tract, which could be made widely available, would be beneficial to patients. Capsule endoscopy is well tolerated by patients but the stomach has proved difficult to visualise accurately with capsule technology due to its’ capacious nature and mucosal folds, which can obscure pathology. MiroCam Navi (Intromedic Ltd, Seoul, Korea) is a capsule endoscope containing a small amount of magnetic material which has been made available with a handheld magnet which might allow a degree of control. This body of work aims to address whether this new technology could be a feasible alternative to conventional flexible endoscopy of the stomach. Methods: Four studies were conducted to test this research question. The first explores the feasibility of magnetically assisted capsule endoscopy of the stomach and operator learning curve in an ex vivo porcine model. This was followed by a randomised, blinded trial comparing magnetically assisted capsule endoscopy to conventional flexible endoscopy in ex vivo porcine stomach models. Subsequently a prospective, single centre randomised controlled trial in humans examined whether magnetically assisted capsule endoscopy could enhance conventional small bowel capsule endoscopy by reducing gastric transit time. Finally a blinded comparison of diagnostic yield of magnetically assisted capsule endoscopy compared to oesophagogastroduodenoscopy was performed in patients with recurrent or refractory iron deficiency anaemia. Results: In the first study all stomach tags were identified in 87.2% of examinations and a learning curve was demonstrated (mean examination times for the first 23 and second 23 procedures 10.28 and 6.26 minutes respectively (p<0.001). In the second study the difference in sensitivities between oesophagogastroduodenoscopy and conventional flexible endoscopy for detecting beads within an ex vivo porcine stomach model was 1.11 (95% CI 0.06, 28.26) proving magnetically assisted capsule endoscopy to be non-inferior to flexible endoscopy. In the first human study, although there was no significant difference in gastric transit time or capsule endoscopy completion rate between the two groups (p=0.12 and p=0.39 respectively), the time to first pyloric image was significantly shorter in the intervention group (p=0.03) suggesting that magnetic control hastens capsular transit to the gastric antrum but cannot impact upon duodenal passage. In the last study, a total of 38 pathological findings were identified in this comparative study of magnetically assisted capsule endoscopy and conventional endoscopy. Of these, 16 were detected at both procedures, while flexible endoscopy identified 14 additional lesions not seen at magnetically assisted capsule endoscopy and magnetically assisted capsule endoscopy detected 8 abnormalities not seen by oesophagogastroduodenoscopy. No adverse events occurred in either of the human trials. Finally magnetically steerable capsule endoscopy induced less procedural pain, discomfort and distress than oesophagogastroduodenoscopy (p=0.0009, p=0.001 and p=0.006 respectively). Conclusion: Magnetically assisted capsule endoscopy is safe, well tolerated and a viable alternative to conventional endoscopy. Further research to develop and improve this new procedure is recommended.

Abstract:
Minimal invasive treatment using tubes such as catheters and endoscopes is well-established. Since the introduction of flexible endoscopy into medical practice, many cases of infectious complications involving bacteria, fungi and viruses have been linked to endoscopic procedures. Inadequate cleaning and disinfection during the reprocessing of the instruments have been reasonable factors as well as insufficient final rinsing and incomplete drying of the endoscope or contaminated flushing equipment for the air/ water-channel. Flexible endoscopes are thermo-labile and cannot withstand heat sterilization processes. Common disinfection processes like ethylene oxide or hydrogen peroxide vapour as well as formaldehyde are more or less effective, but require long contact and aeration times. Furthermore, these processes use toxic and explosive substances. Therefore, the development of new methods for the sterilization of thermo sensitive devices especially with long fine lumen is very important. A promising possibility is the decontamination by plasma discharge treatment. Various plasma setups have been developed. However, due to the complexity of plasma techniques and technologies, setups and parameters, it is impossible to compare their antimicrobial efficacy by single experiments. A standardization of microbiological parameters is necessary to attribute the observed effects solely to the plasma efficacy. This work is based on round robin tests with and without plasma treatment by three institution (the Fraunhofer IGB Stuttgart, Germany; the HygCen GmbH Schwerin, Germany and the INP Greifswald, Germany) and the publications by Maucher et al. (2011) and Schnabel et al. (2012).

Abstract:
Narrow-Band Imaging (NBI) is an optical endoscopic technique using optic filters to select two wavebands from a white light source and revealing mucosal and submucosal vascular patterns. NBI endoscopy is implemented to detect various lesions of the nasal and oral cavity, oropharynx and hypopharynx, and larynx; for finding bleeding vessel in recurrent epistaxis, for more precise tissue biopsy, in the diagnostics of synchronous cancers, for tumours of unknown origin, in defining surgical margins, inflammation and for follow-up of oncologic patients. According to lesion area in otorhinolaryngology, three classifications are known for observation of suspicious lesions: the “IPCL classification” for oral mucosa, the Ni's classification, and the classification recommended by the European Laryngological Society, for vocal cords. The correct recognition of vascular patterns by physician is strongly influenced by the learning curve of the clinician. In line with limits of NBI, a tissue biopsy remains the gold standard for definitive proof of malignancy. However, NBI endoscopy is especially useful tool for early detection of malignant and precursor lesions when the lesions are invisible during classical otorhinolaryngological examination.

Abstract:
Flexible endoscopy, a procedure during which an operator pushes a semi-rigid endoscope through a patient’s gastrointestinal tract, has been the gold-standard screening method for colon cancer screening (colonoscopy) for over 50 years. Owing to the large amounts of tissue stress that result from the need for transmitting a force to the tip of the endoscope while the device wraps through the bowel, implementing a front-actuated endoscopy system has been a popular area of research [1]. The pursuit of such a concept was accelerated by the advent of ingestible capsule endoscopes, which, since then, have been augmented by researchers to include therapeutic capabilities, modalities for maneuverability, amongst other diagnostic functions [2]. One of the more common approaches investigated has been the use of magnetic fields to apply forces and torques to steer the tip of an endoscope [3]. Recent efforts in magnetic actuation have resulted in the use of robot manipulators with permanent magnets at their end effectors that are used to manipulate endoscopes with embedded permanent magnets. Recently, we implemented closed loop control of a tethered magnetic capsule by using real-time magnetic localization and the linearization of a magnetic wrench applied to the capsule by the actuating magnet [4]. This control was implemented in 2 degrees-of-freedom (DoF) in position (in the horizontal plane) and 2 DoF in orientation (panning and tilting). One DoF in position is lost owing to the tethered capsule being actuated in air and thus lacking a restoring force to counter the high field gradient. The 3rd orientation DoF is lost owing to the axial symmetry of the permanent magnet in the capsule; this prevents the application of torque in the axial direction and thus controlled roll and introduces a singularity in the capsule’s actuation. Although another dipole could be used to eliminate this singularity, this would complicate both the actuation and localization methods. In this manuscript, we consider the consequences of the embedded magnet (EM) being radially offset from the center of the capsule while being manipulated by an external actuating magnet (AM). We have developed a tethered capsule endoscope that contains a cylindrical EM (11.11 mm in length and diameter) with a residual flux density of 1.48 T that is offset by 1.85 mm from the center of the capsule; a distance that is less than 10% of the capsule diameter. Our investigation into the topic results from repeated observation of the capsule’s preference to align such that the internal magnet is closest to the actuating magnet (AM). The AM is a cylindrical magnet (101.6 mm in length and diameter) with a residual flux density of 1.48 T that is mounted at the end effector of a 6 DoF manipulator, as seen in Figure 1. In this manuscript, we evaluate the torqueing effects of the presence of this magnet offset with the goal of determining whether the torque effect is negligible, or impacts capsule motion and thus can potentially be used for the benefit of endoscope manipulation. A concept schematic of this effect is shown in Figure 2. A discussion of how to use this torque is beyond the scope of this manuscript. To the authors’ knowledge, the use of such concept in permanent-magnet based control has not been investigated.

Abstract:
For the purpose of realizing the noninvasive exploration of gastrointestinal tract, a novel magnetic propulsion system is proposed, which includes a patient support, a magnet assembly with two groups of permanent magnets positioned oppositely, and a magnet support. The proposed approach exploits permanent magnet and coupling movement of multi-axis components to generate quasi-static magnetic field for controlling the position, orientation, and movement of a self-propelled robotic endoscope in the gastrointestinal tract. By driving the five coupling axes, the proposed magnetic propulsion system is capable of steering the capsule endoscope through the intestinal tract in multi-directions of 2D space. Experiments in simulated intestinal tract are conducted to demonstrate controlled translation, rotation, and rototranslation of capsule endoscope. Finite Element Method is used to analyze navigation system’s mechanical properties and the distributions of magnetic field. The proposed technique has great potential of enabling the application of controlled magnetic navigation in the field of capsule endoscopy.

Abstract:
This study aims to determine the level of pregnancy in goats and sheep in Indonesia, especially in the Yogyakarta area, by comparing the use of conventional AI devices with AI devices equipped with endoscopes. Many factors, including livestock, breeders, officers, spermatozoa, and environmental factors, strongly influence reproductive performance. The process of pregnancy in goats and sheep begins with the process of estrus, mating, pregnancy, birth, and postpartum estrus as the beginning of a continuous cycle. The problem found that the pregnancy rate in goats and sheep is relatively low. The low genetic quality of goats and sheep causes population growth in Yogyakarta to run slowly. This research was conducted by direct observation of the animal’s condition, then observation using an AI smart endoscope. AI Smart endoscopy was used to observe estrus time and followed up with AI in goats that had shown AI time. Observation of pregnancy was carried out two months after AI. The results showed that AI using smart endoscopy AI Gun on 20 goats resulted in 55% pregnancy. This is higher than conventional AI, which is 35%. The success of AI using the estrus synchronization method is 65%. The benefit of this research is the achievement of increasing pregnancy and improving the genetic quality of goats and sheep by using an AI device equipped with an endoscope. The target of veterinarians and field paramedics is more accustomed to using modified AI devices to make it easier to detect estrus. This program is expected to increase both the number of fetuses from an average of only 1-2 to 2-3 births and the success rate of AI increases.

Abstract:
Review question / Objective: With the development of endoscopic techniques, several diagnostic endoscopy methods are available for the diagnosis of malignant lesions, including magnified pigmented endoscopy and narrow band imaging (NBI).The main goal of endoscopy is to achieve the real-time diagnostic evaluation of the tissue, allowing an accurate assessment comparable to histopathological diagnosis based on structural and cellular heterogeneity to significantly improve the diagnostic rate for cancerous tissues. Endocytoscopy (ECS) is based on ultrahigh magnification endoscopy and has been applied to endoscopy to achieve microscopic observation of gastrointestinal (GI) cells through tissue staining, thus allowing the differentiation of cancerous and noncancerous tissues in real time.To date, ECS observation has been applied to the diagnosis of oesophageal, gastric and colorectal tumours and has shown high sensitivity and specificity.Despite the highly accurate diagnostic capability of this method, the interpretation of the results is highly dependent on the operator's skill level, and it is difficult to train all endoscopists to master all methods quickly. Artificial intelligence (AI)-assisted diagnostic systems have been widely recognized for their high sensitivity and specificity in the diagnosis of GI tumours under general endoscopy. Few studies have explored on ECS for endoscopic tumour identification, and even fewer have explored ECS-based AI in the endoscopic identification of GI tumours, all of which have reached different conclusions. Therefore, we aimed to investigate the value of ECS-based AI in detecting GI tumour to provide evidence for its clinical application.

Review question / Objective: To compare the efficacy of high flow nasal oxygen with conventional oxygen therapy to prevent hypoxemia in gastrointestinal endoscopy with conscious sedation. Condition being studied: High flow nasal oxygen, a novel technique, may be an alternative to conventional oxygen therapy. High flow nasal oxygen can deliver heated and humidified oxygen via special nasal cannula with high flow (up to 70 L/min). It has been applied to improve oxygenation in clinical entities, favored by increasing evidence supporting its efficacy. Recently, the use of high flow nasal oxygen has spreaded to gastrointestinal endoscopy. However, the efficacy of high flow nasal oxygen in gastrointestinal endoscopy has not yet been well evaluated due to small sample size of the individual study and conflicting results.
