Study on impact of flexible endoscopy training course for surgeons in India.

Competence in flexible endoscopy is essential for all surgeons during this era of minimal access surgery. However, fewer surgeons have expertise in endoscopy due to a lack of training and interest. The Indian Association of Gastrointestinal Endo Surgeons devised a short-structured training course in the art and science of endoscopy. This study aimed to find the impact of the endoscopy training course (Endoscopic Fellowship of Indian Association of Gastrointestinal Endo Surgeons [EFIAGES]) in improving the endoscopic skill of surgeons. Twenty-two-part electronic survey forms were sent to all 375 candidates who took the course between 2016 and 2019 for this retrospective observational study. The following outcome measures were noted, namely technical competence in endoscopy before the course, delegate feedback about the course modules, volume of endoscopies before and after the course and quality indicators such as reaching up to duodenum (D2) and caecum before and after the course. Statistical analysis of the impact of the course was done using Chi-square test. Responses from 262 out of a total of 375 candidates were received. Seventy-seven per cent of trainees were pleased with content and mode of conduct of the course. The quality indicator of gastroscopy with the ability to reach D2 in 90% of the caseload was achieved by only 28% of trainees before the EFIAGES. This increased to 72% of candidates after the course and similar results were seen with colonoscopy also. Most of the candidates noted a distinct improvement in their endoscopic navigation skills subsequent to the course. Endoscopy skill transfer was possible with a short-structured endoscopy course. The surgical fraternity should realise the importance of endoscopy skills in the current era of surgical practice.

Training and competence in Digestive Endoscopy: Statement Position Paper from the Spanish Society of Digestive Diseases.

Gastrointestinal (GI) Endoscopy is a basic competence for the management of gastrointestinal diseases. However, it should not be regarded as an independent training technique. Rather it is a part of a continuous and accredited process that requires clinical knowledge from the gastroenterologist to keep skills up-to-date in a constantly evolving medical subspecialty. Thus, the only official accredited way for training in GI endoscopy is through the Specialized Health Training program in the Management of the Digestive Diseases administered by the Spanish Ministry of Health.

Up-to-date literature review and issues of sedation during digestive endoscopy.

Sedation is common during digestive endoscopy to provide comfort and pain relief for patients. However, the use of sedation in endoscopy also poses potential risks, and recent issues have been raised regarding its safety and administration. This literature review paper will discuss the most recent developments in the field of sedation in digestive endoscopy, including the adverse events that might be associated with sedation and how to manage it, the legal issues associated with administration, the impact of COVID-19 on sedation practices, and sedation in special situations. It will also touch upon the current guidelines and recommendations for sedation, including the importance of patient selection and monitoring and the need for training and certification for endoscopists administering sedation. The review will also analyse studies evaluating the safety and efficacy of various sedation techniques, including propofol, midazolam, and others. It will examine the benefits and drawbacks of these agents.

Impact of the Coronavirus Disease 2019 Pandemic on Pediatric Gastrointestinal Endoscopy: A Questionnaire-based Internet Survey of 162 Institutional Experiences in Asia Pacific.

The impact of coronavirus 2019 (COVID-19) on gastrointestinal (GI) endoscopy procedures in adults has been reported, with a drastic reduction in the number of procedures. However, there are no sufficient data regarding the impact on pediatric GI endoscopy. Here, we aimed to report that impact in the Asia-Pacific region. A questionnaire-based internet survey was conducted from June to November 2021 among pediatric endoscopy institutions in the Asia-Pacific region, with each institution providing a single response. Overall, 25 questions focused on the impact of the number of procedures conducted, the usage of personal protective equipment (PPE), and endoscopy training programs during the pandemic. A total of 162 institutions across 13 countries in the Asia-Pacific region participated in the study, and 133 (82.1%) institutions underwent procedure changes since the emergence of COVID-19. The number of esophagogastroduodenoscopy and ileocolonoscopy procedures decreased in 118/133 (88.7%) and 112/133 (84.2%) institutions, respectively. Endoscopy for patient with positive COVID-19 in an emergency or urgent cases still carried out in 102/162 (62.9%) institutions. Screening of COVID-19 for all patients before endoscopy was done across 110/162 (67.9%) institutions. PPE recommendations varied among institutions. Pediatric gastrointestinal endoscopy training programs were discontinued in 127/162 (78.4%) institutions. This study reports the impact of the COVID-19 pandemic on pediatric gastrointestinal endoscopy in the Asia-Pacific region. There has been a significant reduction in the number of endoscopic procedures and relevant training programs.

Development and evaluation of a 3d printed training model for endoscopic third ventriculostomy in low-income countries

IntroductionPediatric hydrocephalus is highly prevalent and therefore a major neurosurgical problem in Africa. In addition to ventriculoperitoneal shunts, which have high cost and potential complications, endoscopic third ventriculostomy is becoming an increasingly popular technique especially in this part of the world. However, performing this procedure requires trained neurosurgeons with an optimal learning curve. For this reason, we have developed a 3D printed training model of hydrocephalus so that neurosurgeons without previous experience with endoscopic techniques can acquire these skills, especially in low-income countries, where specific techniques training as this, are relatively absent. Research QuestionOur research question was about the possibility to develop and produce a low-cost endoscopic training model and to evaluate the usefulness and the skills acquired after training with it. Material and MethodsA neuroendoscopy simulation model was developed. A sample of last year medical students and junior neurosurgery residents without prior experience in neuroendoscopy were involved in the study. The model was evaluated by measuring several parameters, as procedure time, number of fenestration attempts, diameter of the fenestration, and number of contacts with critical structures. ResultsAn improvement of the average score on the ETV-Training-Scale was noticed between the first and last attempt (11.6, compared to 27.5 points; p<0.0001). A statistically significant improvement in all parameters, was observed. Discussion and ConclusionThis 3D printed simulator facilitates acquiring surgical skills with the neuroendoscope to treat hydrocephalus by performing an endoscopic third ventriculostomy. Furthermore, it has been shown to be useful to understand the intraventricular anatomical relationships.

Effectiveness of a Mindfulness-Based Intervention in Endoscopy Among Gastroenterology Fellows: A Pilot Study

Learning endoscopy is arguably one of the most exciting aspects of fellowship for the gastroenterology (GI) trainee. However, performing endoscopy carries significant emotional and cognitive challenges, with GI fellows reporting procedural-related stress and burnout1. Specifically, self-critical internal narratives, interpersonal conflicts, and productivity pressure impact endoscopy performance2, with the burden of such stressors reducing learning potential among trainees3. Furthermore, the Coronavirus Disease 2019 pandemic has exacerbated burnout and stress in GI fellowships, forcing trainees to accommodate to restrictive changes in endoscopy training protocols4.

Single or double headed capsules for the investigation of suspected small bowel bleeding: Are two heads better than one

BackgroundCapsule endoscopy is now the accepted first line investigation for suspected small bowel (SB) bleeding. Recent evidence suggests the diagnostic yield for SB pathology may be higher for tailored double headed (DH) SB capsules. Whether other forms of bidirectional capsules offer a similar advantage is less clear.AimTo compare the efficacy of single headed versus bidirectional capsules in detecting pathology in patients with suspected small bowel bleeding.MethodsA single centre prospective comparison study was conducted over an 8 month period in a tertiary care hospital. Patients referred with overt or suspected SB bleeding were assigned to either SB3 Medtronic SB capsule (SH) during the initial four months or PillCam Colon 2 Medtronic capsule (DH) during the subsequent four months. Studies were analysed by trained Capsule Endoscopists and approved by our institutions capsule review board. Findings were compared between SH and DH capsules using a chi2 or t-test as appropriate. A p value of &amp;lt;0.05 was considered significant.Results201 subjects were included, mean age 61.8 years, 90 (45%) male. Majority referred with occult bleeding, 153 (76%). DH and SH capsule used in 100 and 101 cases, respectively. 90% (n=181) capsules were complete and overall diagnostic yield was 57% (n=114). Diagnostic yield was similar between both groups - DH 53% (n=53), SH 60% (n=61). Positive finding in overt bleeding; SH 85% (n=22) versus DH 50% (n=11), p&amp;lt;0.02. SH capsules more frequently detected SB inflammation, 27 (27%) versus 9 (9%), p&amp;lt;0.002. More patients had another diagnosis in the DH (19) than the SH (9), p&amp;lt;0.04, the majority were type 1a vascular lesions, “red spots” or diminutive colonic polyps.ConclusionSingle head and double head capsules perform similary in terms of diagnostic yield overall. This supports the continued use of standard small bowel capsules for investigation of the small bowel.

OGBN O04 Upper Gastrointestinal Training in the UK &amp; Ireland – a Roux Group Study

Abstract Background Surgical training programmes in the United Kingdom and Ireland (UK&amp;I) are in a transition period evidenced by new surgical curricula. This study is the first to collate the opinions of UK&amp;I trainee and consultant surgeons regarding the current Upper Gastrointestinal (UGI) training model. Methods A questionnaire was developed and distributed via national UGI societies and the social media platform, Twitter. A total of 241 responses were received with all UK&amp;I regions represented. Results The median time to Certificate of Completion of Training (CCT) of 13 years was considered reasonable (50.2%), however the majority (67.2%) found training to be unfocused. The suggested targets for publications, presentations and audits were 3–5 (trainee vs consultant &amp;lt;3 vs 3–5, p&amp;lt;0.001), &amp;lt;3 (&amp;lt;3 vs 3–5, p=0.002) and 3–5 (&amp;lt;3 vs 3–5, p&amp;lt;0.001) respectively. The majority (61.9%) considered a higher academic degree advantageous but felt it should not be compulsory. Interestingly, most respondents (63.5%) had or planned to undertake one. Crucially, there were geographical discrepancies in access to training, particularly in bariatrics, robotic surgery, and endoscopy. Proficiency in diagnostic endoscopy was deemed essential for CCT and consultant practice (81.7% and 67.6% respectively). The current index UGI operative requirements were felt to be achievable (87.6%) but inadequate for day one consultant practice (74.7%), an opinion shared by both the trainee and consultant groups (p=0.662). Reassuringly, most respondents (76.3%) deemed there to be a role for on-the-job operative training following consultant appointment. Post-CCT fellowships were not considered necessary for consultant appointment, however the majority (73.6%) again recognised its advantage. Conclusions While variations were seen in the opinions of trainee and consultant surgeons, the current CCT requirements as outlined by the Joint Committee on Surgical Training are consistent with the overall perspective of the UGI community. Areas for improvement include flexibility in geographical working and provisions for endoscopy training, to ensure equal access.

Endoscopy training in the Netherlands: a national survey among gastroenterology residents.

Background and study aims Training in endoscopy is a key objective of gastroenterology residency. There is currently no standardized or systematic training approach. This study evaluated and compared the current status of gastrointestinal endoscopy training programs in all teaching hospitals in the Netherlands from a resident perspective. Materials and methods A national online survey with open and closed questions on gastrointestinal endoscopy training was administered to all gastroenterology residents (N = 180) in the eight educational regions in the Netherlands. Results One hundred residents who had already started endoscopy training were included in the analyses. Sixty-five residents (65 %) were satisfied with their endoscopy training program. Participation in a preclinical endoscopy course was mandatory in seven of eight educational regions. Residents from the region without a mandatory endoscopy training course were significantly less likely to be satisfied with their endoscopy training program (32 %, P = .011). Criteria used to determine the level of supervision differed greatly between teaching hospitals (e. g. assessed endoscopy competence, predefined period of time or number of procedures). Only 26 residents (26 %) reported uniformity in teaching methods and styles between different supervising gastroenterologists in their teaching hospital. Conclusions Although most gastroenterology residents were satisfied with the endoscopy training program and endoscopy supervision in their teaching hospital, this study identified considerable local and regional variability. Future studies should be conducted to evaluate the trainers' perspective and trainers' behavior during endoscopy training sessions, which might eventually lead to the development of best practices regarding endoscopy training, including standardization of training programs and supervision methods.

S27 Interobserver Agreement of Modified Paris Classification and Histology Prediction of Colorectal Lesions in Patients With Inflammatory Bowel Disease

Background: It is recommended by the current SCENIC guidelines (International Consensus Statement on Surveillance and Management of Dysplasia in IBD) that visible dysplasia in patients with longstanding IBD should be endoscopically characterized using a modified Paris classification. The validity of this classification has not been determined. This study aims to measure the interobserver agreement of the Paris and modified Paris classification for IBD visible dysplasia. Secondary endpoints include the endoscopists’ accuracy for pathology prediction and border assessment for each lesion. Methods: A total of 100 de-identified endoscopic still images and 30 videos of IBD visible colorectal lesions were graded by 10 senior and 4 trainee endoscopists from 5 tertiary care centers. The endoscopists were asked to assign 4 classifications for each image: 1. Standard Paris, 2. Modified Paris, 3. Pathology prediction (dysplastic, non-dysplastic or serrated) and 4. Lesion Border: distinct or indistinct. Agreement was measured using Light’s Kappa coefficient. Consensus of ratings was assessed according to strict majority. If no majority was achieved, consensus was recorded as “none.” Results: The overall Light’s Kappa for all study endpoints was between 0.32 and 0.49. In subgroup analysis between junior and senior endoscopists, Light’s Kappa continued to be less than 0.6 with a slightly higher agreement amongst juniors. Lesions with lowest agreement and no consensus were mostly classified as Is, IIa and mixed for Paris and sessile and superficial elevated for modified Paris classifications. Endoscopists’ accuracy for prediction of dysplastic, non-dysplastic and serrated pathology was 77%, 56% and 30% respectively. There was a strong association (P < 0.001) between the given morphology classification and the predicted pathology with Ip lesions carrying a much lower expectation of dysplasia than Is/IIc/III and mixed lesions. The agreement for border prediction was 0.5 for junior and 0.3 for senior endoscopists. Conclusion(s): This study demonstrates very low IOA for Paris and Modified Paris classifications and low accuracy and IOA for lesion histopathology prediction. Revisions of these classifications are required to create a clinically useful risk stratification tool and enable eventual application of augmented intelligence tools.

Eye tracking technology in endoscopy: Looking to the future.

The visual patterns of an endoscopist, that is, what the endoscopist is looking at during luminal endoscopy, is an interesting area with an evolving evidence base. The tools required for gaze analysis have become cheaper and more easily accessible. A comprehensive literature search was undertaken identifying 19 relevant papers. Gaze analysis has been used to identify certain visual patterns associated with higher polyp detection rates. There have also been increasing applications of gaze analysis as an objective study tool to compare the effectiveness of endoscopic imaging technologies. Gaze analysis also has the potential to be incorporated into endoscopic training. Eye movements have been used to control and steer a robotic endoscope. This review presents the current evidence available in this novel and evolving field of endoscopic research.

Current Endoscopy Training in Korea and Future Aspects

The training of trainees to perform endoscopies is challenging. There is no standardized training program in Korea. Trainees usually learn to perform endoscopies under the supervision of an educator, an expert endoscopist. However, most of educators have never received formal training. For high quality and effecting training, formal training program for educators is needed. Also, specific assessment tools measuring performance and improving training are required. The use of simulators for acquiring, maintaining, and assessing skills in endoscopy has grown over the past decade. Many data suggest that simulation training may accelerate the acquisition of specific technical skills in endoscopy early in training. If we include education using simulators in basic endoscopy education, it will be of great help to shorten the endoscopy training time and improve the endoscopy training environment. A significant portion of medical lawsuits against gastroenterologists in Korea are related to complications related to sedation. Therefore, endoscopy education should include contents related to sedation education. Also, systematic and thorough education program along with assessment tool measuring true competence of sedation in endoscopy is needed. Changes should be made at all levels to improve our endoscopy training system.

The colonoscopic vacuum model–simulating biomechanical restrictions to provide a realistic colonoscopy training environment

IntroductionPracticing endoscopic procedures is fundamental for the education of clinicians and the benefit of patients. Despite a diverse variety of model types, there is no system simulating anatomical restrictions and variations in a flexible and atraumatic way. Our goal was to develop and validate a new modelling approach for adhesion forces between colon and abdominal wall.MethodsAn inlay for a standard mechanical trainer was designed and 3D printed. Colon specimens were fixed to the inlay along colon ascendens (CA) and colon descendens (CD) by a vacuum. Our system, which we refer to as Colonoscopy Vacuum Model (CoVaMo), was validated with 11 test persons with varying level of expertise. Each performed one colonoscopy and one polypectomy in the CoVaMo and in the Endoscopic Laparoscopic Interdisciplinary Training Entity (ELITE). Achieved adhesion forces, times required to fulfill different tasks endoscopically and a questionnaire, assessing proximity to reality, were recorded.ResultsMean adhesion forces of 37 ± 7 N at the CA and 30 ± 15 N at the CD were achieved. Test subjects considered CoVaMo more realistic than ELITE concerning endoscope handling and the overall anatomy. Participants needed statistically significantly more time to maneuver from anus to flexura sinistra in CoVaMo (377 s ± 244 s) than in ELITE (58 s ± 49 s).ConclusionWe developed a training environment enabling anatomically and procedural realistic colonoscopy training requiring participants to handle all endoscope features in parallel. Fixation forces compare to forces needed to tear pig colon off the mesentery. Workflow and inlay can be adapted to any arbitrary ex vivo simulator.

Interobserver agreement of the modified Paris classification and histology prediction of colorectal lesions in patients with inflammatory bowel disease

SCENIC (International Consensus Statement on Surveillance and Management of Dysplasia in IBD) guidelines recommend that visible dysplasia in patients with longstanding inflammatory bowel disease (IBD) should be endoscopically characterized using a modified Paris classification. This study aimed to determine the interobserver agreement (IOA) of the modified Paris classification and endoscopists' accuracy for pathology prediction of IBD visible lesions. One hundred deidentified endoscopic still images and 30 videos of IBD visible colorectal lesions were graded by 10 senior and 4 trainee endoscopists from 5 tertiary care centers. Endoscopists were asked to assign 4 classifications for each image: the standard Paris classification, modified Paris classification, pathology prediction, and lesion border. Agreement was measured using Light's kappa coefficient. Consensus of ratings was assessed according to strict majority. The overall Light's kappa for all study endpoints was between .32 and .49. In a subgroup analysis between junior and senior endoscopists, Light's kappa continued to be less than .6 with a slightly higher agreement among juniors. Lesions with the lowest agreement and no consensus were mostly classified as Is, IIa, and mixed Paris classification and sessile and superficial elevated for modified Paris classification. Endoscopist accuracy for prediction of dysplastic, nondysplastic, and serrated pathology was 77%, 56%, and 30%, respectively. There was a strong association (P< .001) between the given morphology classification and the predicted pathology with Ip lesions carrying a much lower expectation of dysplasia than Is/IIc/III and mixed lesions. The agreement for border prediction was .5 for junior and .3 for senior endoscopists. This study demonstrates very low IOA for Paris and modified Paris classifications and low accuracy and IOA for lesion histopathology prediction. Revisions of these classifications are required to create a clinically useful risk stratification tool and enable eventual application of augmented intelligence tools.

Endoscopic Retrograde Cholangiopancreatography Performed by Trainees Is Not Associated with Increased Immediate Adverse Events or Technical Failure Rates.

Training endoscopists to perform endoscopic retrograde cholangiopancreatography (ERCP) is critical to address the increasing patient population with pancreatobiliary diseases. Concerns remain about ERCP safety and success involving trainees. We compared the technical success and immediate adverse events between ERCP with and without trainee involvement. Retrospective analysis of 28,271 ERCP procedures in a national sample of the United States over 12years. Demographics, procedure and fluoroscopy time, visualization and cannulation of main structures, adverse events, and technical success rates were compared between ERCP with and without trainees. Categorical variables were compared using Pearson's chi-square test and continuous variables using a standard t-test. Univariate and multivariate regressions were performed adjusting for age, gender, ethnicity, US region, ASA class and clinical setting. Approximately 49.5% of ERCPs had a trainee involved. The ampulla was visualized in 97.4% with trainee vs. 97.3% without trainee involvement (P = 0.858). The common bile duct was visualized and cannulated in 90.4% with trainees vs. 91.7% without trainees involved (P < 0.001). The ERCP was incomplete in 5.9% of cases with trainees vs. 6.4% without trainees involved (P = 0.207). Trainee participation added 8.7min to average procedure time (aOR: 1.02, P < 0.001) and 2.0min to fluoroscopy time (aOR: 1.00, P = 0.796). Adverse events (aOR: 0.89, P = 0.704) and technical success (aOR: 0.83, P = 0.571) were similar in both groups. Trainee involvement leads to increased procedure duration but is not associated with increased immediate adverse events, or technical failure. Our study supports ERCP safety and success with trainee participation.

Endoscopy training in Australia during COVID-19: Efficacy and knowledge assessment of gastroenterology and general surgery trainees.

During COVID-19, restrictions to elective endoscopy were introduced worldwide. A reduction in procedures may impact trainees' endoscopy learning. This study aims to assess Australian advanced gastroenterology and general surgery trainees' self-perceived efficacy and knowledge in endoscopy during the pandemic. All Australian gastroenterology and general surgery trainees in their last 2 years of accredited training were invited to participate through email (2020-2021 and 2021-2022 training cycles). The primary outcome was to assess trainees' self-efficacy and knowledge regarding gastrointestinal endoscopy. Secondary outcomes included subgroup analysis between gastroenterology and general surgery trainees. Self-perceived efficacy was assessed with Likert-scale questions on 20 endoscopy procedures and knowledge was assessed through 21 endoscopy-related multiple choice questions. Eighty-one trainees responded to a self-efficacy questionnaire and 77 responded to the knowledge questionnaire. Over 90% of the trainees were confident or extremely confident in diagnostic endoscopy, but only half demonstrated similar efficacy for therapeutic endoscopy. The efficacy for basic endoscopy procedures was higher for gastroenterology trainees (64.0% vs 51.1%, P< 0.001). Last-year trainee achievement of conjoint committee requirements for upper gastrointestinal endoscopy was achieved in 95.8% of gastroenterology trainees versus 22.2% of surgical trainees (P< 0.001). The median score on the knowledge questionnaire was also higher for the gastroenterology subset (90.5% vs 71.4%, P< 0.001). During COVID-19, endoscopy trainees' self-efficacy in endoscopic diagnostic procedures was achieved for most trainees. The differences in self-perceived efficacy and knowledge between gastroenterology and surgical trainees may be reflective of the different opportunities for learning between the two groups.

Neuroendoscopic Surgery for Pediatric Intraventricular Tumors

Various tumors are found in ventricles and tissues surrounding the ventricles in children, adolescents, and young-adult patients. They cause cerebrospinal fluid pathway obstruction, resulting in hydrocephalus and isolated ventricles. In this paper we describe a neoplasm arising from the lateral and third ventricle. Intraventricular tumors are good candidates for neuroendoscopic surgery. Firstly, minimally invasive and established procedures, neuroendoscopic biopsy with flexible endoscopy or rigid endoscopy, are performed. These endoscopic biopsies can be performed concurrently with other procedures, such as third ventriculostomy or septostomy, to improve cerebrospinal fluid circulation. Neuroendoscopic biopsy for intraventricular tumor is associated with high diagnostic yield and relatively low incidence of morbidity and mortality, compared with open surgery. Endoscopic diagnostic procedure also can be applied in patients without ventricular dilatation, assisted by neuronavigation or echo-guided equipment. Secondly, neuroendoscopic cylinder surgery also makes it possible to remove intraventricular tumors with less damage. The two hands technique with rigid endoscopy helps debulking and hemostasis during tumor removal. Further developments in endoscopic equipment and training systems aimed at enhancing cooperation between the operator and assistant should be expected in the future. Neuroendoscopic resection appears to be a safe and reliable treatment option for patients with intraventricular tumors.
