Dương TQ, Soldera J. Virtual reality tools for training in gastrointestinal endoscopy: A systematic review. Artif Intell Gastrointest Endosc 2024; 5:92090. [DOI: 10.37126/aige.v5.i2.92090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 02/11/2024] [Accepted: 04/07/2024] [Indexed: 05/11/2024] Open
Abstract
BACKGROUND Virtual reality (VR) has emerged as an innovative technology in endoscopy training, providing a simulated environment that closely resembles real-life scenarios and offering trainees a valuable platform to acquire and enhance their endoscopic skills. This systematic review will critically evaluate the effectiveness and feasibility of VR-based training compared to traditional methods.
AIM To evaluate the effectiveness and feasibility of VR-based training compared to traditional methods. By examining the current state of the field, this review seeks to identify gaps, challenges, and opportunities for further research and implemen-tation of VR in endoscopic training.
METHODS The study is a systematic review, following the guidelines for reporting systematic reviews set out by the PRISMA statement. A comprehensive search command was designed and implemented and run in September 2023 to identify relevant studies available, from electronic databases such as PubMed, Scopus, Cochrane, and Google Scholar. The results were systematically reviewed.
RESULTS Sixteen articles were included in the final analysis. The total number of participants was 523. Five studies focused on both upper endoscopy and colonoscopy training, two on upper endoscopy training only, eight on colon-oscopy training only, and one on sigmoidoscopy training only. Gastro-intestinal Mentor virtual endoscopy simulator was commonly used. Fifteen reported positive results, indicating that VR-based training was feasible and acceptable for endoscopy learners. VR technology helped the trainees enhance their skills in manipulating the endoscope, reducing the procedure time or increasing the technical accuracy, in VR scenarios and real patients. Some studies show that the patient discomfort level decreased significantly. However, some studies show there were no significant differences in patient discomfort and pain scores between VR group and other groups.
CONCLUSION VR training is effective for endoscopy training. There are several well-designed randomized controlled trials with large sample sizes, proving the potential of this innovative tool. Thus, VR should be more widely adopted in endoscopy training. Furthermore, combining VR training with conventional methods could be a promising approach that should be implemented in training.

Abstract
BACKGROUND AND AIM To explore the feasibility of a standardized training and assessment system for magnetically controlled capsule gastroscopy (MCCG). METHODS The results of 90 trainees who underwent the standardized training and assessment system of the MCCG at the First Affiliated Hospital of Xi'an Jiaotong University from May 2020 to November 2023 was retrospectively analyzed. The trainees were divided into three groups according to their medical backgrounds: doctor, nurse, and non-medical groups. The training and assessment system adopted the '7 + 2' mode, seven days of training plus two days of theoretical and operational assessment. The passing rates of theoretical, operational, and total assessment were the primary outcomes. Satisfaction and mastery of the MCCG was checked. RESULTS Ninety trainees were assessed; theoretical assessment's passing rates in the three groups were 100%. The operational and total assessment passing rates were 100% (25/25), 97.92% (47/48), and 94.12% (16/17), for the doctor, nurse, and non-doctor groups respectively, with no significant difference (χ2 = 1.741, p = 0.419). No bleeding or perforation occurred during the procedure. Approximately, 96.00% (24/25), 95.83% (46/48), and 94.12% (16/17) of the doctor, nurse and non-medical groups anonymously expressed great satisfaction, respectively, without statistically significant difference (χ2 = 0.565, p = 1.000). The average follow-up time was 4-36 months, and 87 trainees (96.67%) had mastered the operation of the MCCG in daily work. CONCLUSIONS Standardized training and assessment of magnetically controlled capsule endoscopists is effective and feasible. Additionally, a strict assessment system and long-term communication and learning can improve teaching effects.

Abstract
The number and variety of applications of artificial intelligence (AI) in gastrointestinal (GI) endoscopy is growing rapidly. New technologies based on machine learning (ML) and convolutional neural networks (CNNs) are at various stages of development and deployment to assist patients and endoscopists in preparing for endoscopic procedures, in detection, diagnosis and classification of pathology during endoscopy and in confirmation of key performance indicators. Platforms based on ML and CNNs require regulatory approval as medical devices. Interactions between humans and the technologies we use are complex and are influenced by design, behavioural and psychological elements. Due to the substantial differences between AI and prior technologies, important differences may be expected in how we interact with advice from AI technologies. Human–AI interaction (HAII) may be optimised by developing AI algorithms to minimise false positives and designing platform interfaces to maximise usability. Human factors influencing HAII may include automation bias, alarm fatigue, algorithm aversion, learning effect and deskilling. Each of these areas merits further study in the specific setting of AI applications in GI endoscopy and professional societies should engage to ensure that sufficient emphasis is placed on human-centred design in development of new AI technologies.

Abstract
BACKGROUND There are limited studies on the impact of gender on training and career advancement in gastroenterology. AIM The aim was to study this impact and understand the perceptions of work-life balance and beliefs regarding gender dynamics among gastroenterologists in India and other South Asian countries. METHODS A web-based survey was conducted among trainees and attending physicians in South Asia from November 15, 2021, to March 30, 2022. The survey instrument had four components: demographic features, training, career advancement and work-life balance. RESULTS As many as 622 gastroenterologists completed the survey, of which 467 responses were from India (mean age: 41.1 years; females: 11.5%). A higher proportion of female respondents from India believed that gender bias in recruiting and training had negatively impacted their careers (40.7% females vs. 1.5% males). Radiation hazard for fertility (11.1% females vs. 1.9% males, p < 0.001) and as a health concern (14.8% females vs. 5.1% males, p = 0.005) were significant career deterrents for females. A higher proportion of female participants from India faced a career interruption (59.3% females vs. 30.3% males, p ≤ 0.001). Common reasons were pregnancy (37%) and childcare provision (25.9%). More females believed that women were more productive than men (40.8% females vs. 16.9% males, p < 0.001) and that a salary gap existed (44.7% females vs. 29.1% males, p < 0.001). The incidence of self-perceived burnout was 63% among females and 51.6% among males (p = 0.115). CONCLUSION Gender-related factors impact the training and career of female gastroenterologists.

Abstract
The European Society of Gastrointestinal Endoscopy (ESGE) has recognized the need to formalize and enhance training in diagnostic endoscopic ultrasound (EUS). This manuscript represents the outcome of a formal Delphi process resulting in an official Position Statement of the ESGE and provides a framework to develop and maintain skills in diagnostic EUS. This curriculum is set out in terms of the prerequisites prior to training; the recommended steps of training to a defined syllabus; the quality of training; and how competence should be defined and evidenced before independent practice. 1: Trainees should have achieved competence in upper gastrointestinal endoscopy before training in diagnostic EUS. 2: The development of diagnostic EUS skills by methods that do not involve patients is advisable, but not mandatory, prior to commencing formal training in diagnostic EUS. 3: A trainee's principal trainer should be performing adequate volumes of diagnostic EUSs to demonstrate maintenance of their own competence. 4: Training centers for diagnostic EUS should offer expertise, as well as a high volume of procedures per year, to ensure an optimal level of quality for training. Under these conditions, training centers should be able to provide trainees with a sufficient wealth of experience in diagnostic EUS for at least 12 months. 5: Trainees should engage in formal training and supplement this with a range of learning resources for diagnostic EUS, including EUS-guided fine-needle aspiration and biopsy (FNA/FNB). 6: EUS training should follow a structured syllabus to guide the learning program. 7: A minimum procedure volume should be offered to trainees during diagnostic EUS training to ensure that they have the opportunity to achieve competence in the technique. To evaluate competence in diagnostic EUS, trainees should have completed a minimum of 250 supervised EUS procedures: 80 for luminal tumors, 20 for subepithelial lesions, and 150 for pancreaticobiliary lesions. At least 75 EUS-FNA/FNBs should be performed, including mostly pancreaticobiliary lesions. 8: Competence assessment in diagnostic EUS should take into consideration not only technical skills, but also cognitive and integrative skills. A reliable valid assessment tool should be used regularly during diagnostic EUS training to track the acquisition of competence and to support trainee feedback. 9: A period of supervised practice should follow the start of independent activity. Supervision can be delivered either on site if other colleagues are already practicing EUS or by maintaining contacts with the training center and/or other EUS experts. 10: Key performance measures including the annual number of procedures, frequency of obtaining a diagnostic sample during EUS-FNA/FNB, and adverse events should be recorded within an electronic documentation system and evaluated.

Abstract
At the end of the last century, a far-sighted 'working party' held in Sydney, Australia addressed the clinicopathological issues related to gastric inflammatory diseases. A few years later, an international conference held in Houston, Texas, USA critically updated the seminal Sydney classification. In line with these initiatives, Kyoto Global Consensus Report, flanked by the Maastricht-Florence conferences, added new clinical evidence to the gastritis clinicopathological puzzle.The most relevant topics related to the gastric inflammatory diseases have been addressed by the Real-world Gastritis Initiative (RE.GA.IN.), from disease definitions to the clinical diagnosis and prognosis. This paper reports the conclusions of the RE.GA.IN. consensus process, which culminated in Venice in November 2022 after more than 8 months of intense global scientific deliberations. A forum of gastritis scholars from five continents participated in the multidisciplinary RE.GA.IN. consensus. After lively debates on the most controversial aspects of the gastritis spectrum, the RE.GA.IN. Faculty amalgamated complementary knowledge to distil patient-centred, evidence-based statements to assist health professionals in their real-world clinical practice. The sections of this report focus on: the epidemiology of gastritis; Helicobacter pylori as dominant aetiology of environmental gastritis and as the most important determinant of the gastric oncogenetic field; the evolving knowledge on gastric autoimmunity; the clinicopathological relevance of gastric microbiota; the new diagnostic horizons of endoscopy; and the clinical priority of histologically reporting gastritis in terms of staging. The ultimate goal of RE.GA.IN. was and remains the promotion of further improvement in the clinical management of patients with gastritis.

Abstract
This ESGE Position Statement provides structured and evidence-based guidance on the essential requirements and processes involved in training in basic gastrointestinal (GI) endoscopic procedures. The document outlines definitions; competencies required, and means to their assessment and maintenance; the structure and requirements of training programs; patient safety and medicolegal issues. 1: ESGE and ESGENA define basic endoscopic procedures as those procedures that are commonly indicated, generally accessible, and expected to be mastered (technically and cognitively) by the end of any core training program in gastrointestinal endoscopy. 2: ESGE and ESGENA consider the following as basic endoscopic procedures: diagnostic upper and lower GI endoscopy, as well as a limited range of interventions such as: tissue acquisition via cold biopsy forceps, polypectomy for lesions ≤ 10 mm, hemostasis techniques, enteral feeding tube placement, foreign body retrieval, dilation of simple esophageal strictures, and India ink tattooing of lesion location. 3: ESGE and ESGENA recommend that training in GI endoscopy should be subject to stringent formal requirements that ensure all ESGE key performance indicators (KPIs) are met. 4: Training in basic endoscopic procedures is a complex process and includes the development and acquisition of cognitive, technical/motor, and integrative skills. Therefore, ESGE and ESGENA recommend the use of validated tools to track the development of skills and assess competence. 5: ESGE and ESGENA recommend incorporating a multimodal approach to evaluating competence in basic GI endoscopic procedures, including procedural thresholds and the measurement and documentation of established ESGE KPIs. 7: ESGE and ESGENA recommend the continuous monitoring of ESGE KPIs during GI endoscopy training to ensure the trainee's maintenance of competence. 9: ESGE and ESGENA recommend that GI endoscopy training units fulfil the ESGE KPIs for endoscopy units and, furthermore, be capable of providing the dedicated personnel, infrastructure, and sufficient case volume required for successful training within a structured training program. 10: ESGE and ESGENA recommend that trainers in basic GI endoscopic procedures should be endoscopists with formal educational training in the teaching of endoscopy, which allows them to successfully and safely teach trainees.

Exploring Endoscopic Competence in Gastroenterology Training: A Simulation-Based Comparative Analysis of GAGES, DOPS, and ACE Assessment Tools. ADVANCES IN MEDICAL EDUCATION AND PRACTICE 2024; 15:75-84. [PMID: 38312535 PMCID: PMC10838491 DOI: 10.2147/amep.s427076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 01/09/2024] [Indexed: 02/06/2024]
Abstract
Purpose Accurate and convenient evaluation tools are essential to document endoscopic competence in Gastroenterology training programs. The Direct Observation of Procedural Skills (DOPS), Global Assessment of Gastrointestinal Endoscopic Skills (GAGES), and Assessment of Endoscopic Competency (ACE) are widely used validated competency assessment tools for gastrointestinal endoscopy. However, studies comparing these 3 tools are lacking, leading to lack of standardization in this assessment. Through simulation, this study seeks to determine the most reliable, comprehensive, and user-friendly tool for standardizing endoscopy competency assessment. Methods A mixed-methods quantitative-qualitative approach was utilized with sequential deductive design. All nine trainees in a gastroenterology training program were assessed on endoscopic procedural competence using the Simbionix Gi-bronch-mentor high-fidelity simulator, with 2 faculty raters independently completing the 3 assessment forms of DOPS, GAGES, and ACE. Psychometric analysis was used to evaluate the tools' reliability. Additionally, faculty trainers participated in a focused group discussion (FGD) to investigate their experience in using the tools. Results For upper GI endoscopy, Cronbach's alpha values for internal consistency were 0.53, 0.8, and 0.87 for ACE, DOPS, and GAGES, respectively. Inter-rater reliability (IRR) scores were 0.79 (0.43-0.92) for ACE, 0.75 (-0.13-0.82) for DOPS, and 0.59 (-0.90-0.84) for GAGES. For colonoscopy, Cronbach's alpha values for internal consistency were 0.53, 0.82, and 0.85 for ACE, DOPS, and GAGES, respectively. IRR scores were 0.72 (0.39-0.96) for ACE, 0.78 (-0.12-0.86) for DOPS, and 0.53 (-0.91-0.78) for GAGES. The FGD yielded three key themes: the ideal tool should be scientifically sound, comprehensive, and user-friendly. Conclusion The DOPS tool performed favourably in both the qualitative assessment and psychometric evaluation to be considered the most balanced amongst the three assessment tools. We propose that the DOPS tool be used for endoscopic skill assessment in gastroenterology training programs. However, gastroenterology training programs need to match their learning outcomes with the available assessment tools to determine the most appropriate one in their context.

Georgiou K, Boyanov N, Antonakis P, Thanasas D, Sandblom G, Enochsson L. Validity of a virtual reality endoscopic retrograde cholangiopancreatography simulator: can it distinguish experts from novices? Front Surg 2023; 10:1289197. [PMID: 38125582 PMCID: PMC10731023 DOI: 10.3389/fsurg.2023.1289197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 11/21/2023] [Indexed: 12/23/2023] Open
Abstract
Background There is a lack of evidence regarding the effectiveness of virtual simulators as a means to acquire hands-on exposure to endoscopic retrograde cholangiopancreatography (ERCP). The present study aimed to assess the outcome and construct validity of virtual ERCP when training on the GI II Mentor simulator. Methods A group of seven experienced endoscopists were compared with 31 novices. After a short introduction, they were requested to carry out three virtual ERCP procedures: diagnosing and removing a common bile duct (CBD) stone; diagnosing and taking brush cytology from a hilar stenosis; and, finally, diagnosing and treating a cystic leakage with a BD stent. For each task, the total time required to complete the task, time required to correctly view the papilla, total time of irradiation, time to deep cannulation, time to define diagnosis, time to complete sphincterotomy, and time to complete the respective intervention were measured. Cannulation of the BD, correct diagnosis, sphincterotomy, and time to complete intervention were assessed by an assessor blinded to the status of the endoscopist who performed the virtual ERCP. Results The time required to visualize the papilla and to cannulate deeply when removing the BD stone was significantly shorter for the experts (both p < 0.05). The time to visualize the papilla, cannulate deeply, reach a diagnosis, complete sphincterotomy, and complete the intervention was significantly shorter for the experts when managing cystic leakage (all p < 0.05). In diagnosing and taking brush cytology from a hilar stenosis, there was only a trend toward the experts needing less time for the deep cannulation of the BD (p = 0.077). Conclusion The performance differed between experts and novices, especially in the management of cystic leakage. This corroborates the construct validity of the GI II Mentor simulator.

Abstract
BACKGROUND Gaming is a growing industry, having met an exponential growth amid the pandemic context. Video games improve the allocation and speed of attention and provide better spatial orientation in visual processing. These same qualities are sought after in GI endoscopists. This study aimed to investigate whether individuals with a gaming history have superior fine motor and visual skills on a virtual reality (VR) endoscopy simulator and if gaming consoles could be added as a proficiency tool in acquiring endoscopic skills. METHODS Firstly, subjects' baseline psychomotor skills and hand-eye coordination were tested using a VR simulator. Secondly, subjects were assigned to either group C and asked to refrain from any gaming for 14 days, or group T, who were asked to play on a console for 14 days. All subjects were then retested. RESULTS 81 students were included in the study. Baseline VR simulator testing showed better scores in those with a higher number of previous gaming hours (0 h-1598, 0 to 30 h-1970, 30 to 50 h-2150, 50 to 100 h-2395, > 100 h-2519; p < 0.05), with males outperforming females (p < 0.01). After spending an average of 19 h gaming, all parameters showed noteworthy improvement for those in group T (p < 0.01). No improvement was seen in group C. CONCLUSIONS Subjects who engage in console gaming have superior psychomotor skills and perform better on VR simulators. Approximately 20 h of console gaming can improve one's simulator skills. With consoles being accessible, entertaining, and cheap, they could be used as an additional training platform for GI endoscopy residents.

Abstract
Background and study aim Simulator-based training has been extensively studied in training gastroduodenoscopy and colonoscopy and shown to significantly improve learning curves of novices. Data on simulator-based training in endoscopic retrograde cholangiopancreatography (ERCP) are scarce. We aimed to determine the impact of 2-day intensive hands-on simulator training on the course of the learning curve of novice trainees. Methods We conducted a prospective cohort study using a validated mechanical ERCP simulator (Boškoski-Costamagna ERCP Trainer). Six trainees were allocated to the simulation course program (SG). Each of these trainees were paired with an endoscopy trainee starting regular ERCP training at the same center who had no exposure to a simulation course program (control group; CG). The course included lectures, live ERCP demonstrations, and hands-on ERCP training to educate trainees in basic techniques related to cannulation, stent placement, stone extraction and stricture management. After the course, both the SG and CG started formal ERCP training in their respective centers. The Rotterdam Assessment Form for ERCP was used to register each performed ERCP. Simple moving average was applied to create learning curves based on successful common bile duct (CBD) cannulation. Outcomes were plotted against a historical cohort (HC). Results Thirteen trainees were included, six trainees in the SG and seven trainees in the CG, with a total of 717 ERCPs. Mean successful ERCP cannulation rate was higher for the simulator group at baseline compared to both CG and HC, 64% versus 43% and 42%, respectively. Differences became less explicit after 40 ERCPs, but persisted until a median of 75 ERCPs. Conclusions We demonstrate that 2-day hands-on simulator-based ERCP training course has a positive effect on the learning curves of ERCP trainees and should be considered an integral part of the training curricula for ERCP to develop skills prior to patient-based training.

Abstract
Background and aims Gastrointestinal (GI) endoscopy in pediatric setting has unique features and, therefore, requires an approach that is tailored to pediatric practice. There is still heterogeneity between training programs worldwide in terms of duration, number of procedures and assessment during and at the end of the training process. Methods We conducted a narrative review aiming to describe and summarize the existing literature on the various training methods for pediatric GI endoscopy to highlight the significance of specific pediatric endoscopy training. Results Simulation-based tools have been implemented in several training programs, providing a safer learning environment for trainees, especially in their earlier stages of training. Assessment of competence is gradually shifting from the sole evaluation of procedural numbers towards the development of more reliable and valid tools that can accurately measure technical competence. Despite such seismic shift, there is still a need for a standardized and comprehensive pediatric-oriented endoscopy curriculum that incorporates acquisition of procedural skills education and is built on the current competency-based model of training. All the above must sink their roots in trainees and to ensure that the endoscopists of tomorrow are capable of delivering high quality of care for children undergoing endoscopy. Conclusion It is crucial to parallelly focus on the way trainers teach trainees. In this context, the implementation of "train the trainers" courses has improved important quality meters in GI endoscopy. Future research should put the focus on the potential subsequent favorable benefits of these changes on child health.

Abstract
BACKGROUND For endoscopists, knowledge of the available hemotherapeutic devices and materials as well as competence in using them is a life-saving expertise in the treatment of patients with acute gastrointestinal bleeding. These competences can be acquired in training on live animals, animal organs, or simulators. We present an animal tissue-free training model of the upper gastrointestinal tract for bleeding therapy. METHODS An artificial, animal tissue-free mucosa and submucosa with the opportunity of injection and clipping therapy were created first. Patches with this artificial mucosa and submucosa were placed into silicone and latex organs with human-like anatomy. Esophageal bleeding situations were imitated as variceal bleeding and bleeding of a reflux esophagitis in latex organs. Finally, a modular training model with human anatomy and replaceable bleeding sources was created. Evaluation of the novel model for gastroscopic training was performed in a multicentric setting with endoscopic beginners and experts. RESULTS Evaluation was carried out by 38 physicians with different levels of education in endoscopy. Evaluation of the model was made with grades from one (excellent) to six (bad): suitability for endoscopic training was 1.4, relevance of the endoscopic training was 1.6, and grading for haptic and optic impression of the model was 1.7. CONCLUSIONS The creation of a gastroscopic model for the training of hemostatic techniques without animal tissues was possible and multiple endoscopic bleeding skills could be trained in it. Evaluation showed good results for this new training option, which could be used in every endoscopic unit or other places without hygienic doubts.

Abstract
Context 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. Aims 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. Settings and Design 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. Subjects and Methods 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 Used Statistical analysis of the impact of the course was done using Chi-square test. Results 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. Conclusions 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.

Abstract
Obesity is a chronic, relapsing, degenerative, multifactorial disease that is associated with many co-morbidities. The global increasing burden of obesity has led to calls for an urgent need for additional treatment options. Given the rapid expansion of bariatric endoscopy and bariatric surgery across Europe, the European Society of Gastrointestinal Endoscopy (ESGE) has recognized the need to formalize and enhance training in bariatric endoscopy and the endoscopic treatment of bariatric surgical adverse events. This manuscript represents the outcome of a formal Delphi process resulting in an official Position Statement of the ESGE and provides a framework to develop and maintain skills in bariatric endoscopy and the endoscopic treatment of bariatric surgical adverse events. This curriculum is set out in terms of the prerequisites prior to training, minimum number of procedures, the steps for training and quality of training, and how competence should be defined and evidenced before independent practice. 1: ESGE recommends that every endoscopist should have achieved competence in upper gastrointestinal endoscopy before commencing training in bariatric endoscopy and the endoscopic treatment of bariatric surgical adverse events. 2: Trainees in bariatric endoscopy and the endoscopic treatment of the complications of bariatric surgery should have basic knowledge of the definition, classification, and social impact of obesity, its pathophysiology, and its related co-morbidities. The recognition and management of gastrointestinal diseases that are more common in patients with obesity, along with participation in multidisciplinary teams where obese patients are evaluated, are mandatory. 3 : ESGE recommends that competency in bariatric endoscopy and the endoscopic treatment of the complications of bariatric surgery can be learned by attending validated training courses on simulators initially, structured training courses, and then hands-on training in tertiary referral centers.

Abstract
Background and study aims Credentialing, the process through which an institution assesses and validates an endoscopist's qualifications to independently perform a procedure, can vary by region and country. Little is known about these inter-societal and geographic differences. We aimed to systematically characterize credentialing recommendations and requirements worldwide. Methods We conducted a systematic review of credentialing practices among gastrointestinal and endoscopy societies worldwide. An electronic search as well as hand-search of World Endoscopy Organization members' websites was performed for credentialing documents. Abstracts were screened in duplicate and independently. Data were collected on procedures included in each document (e. g. colonoscopy, ERCP) and types of credentialing statements (procedural volume, key performance indicators (KPIs), and competency assessments). The primary objective was to qualitatively describe and compare the available credentialing recommendations and requirements from the included studies. Descriptive statistics were used to summarize data when appropriate. Results We screened 653 records and included 20 credentialing documents from 12 societies. Guidelines most commonly included credentialing statements for colonoscopy, esophagogastroduodenoscopy (EGD), and ERCP. For colonoscopy, minimum procedural volumes ranged from 150 to 275 and adenoma detection rate (ADR) from 20 % to 30%. For EGD, minimum procedural volumes ranged from 130 to 1000, and duodenal intubation rate of 95 % to 100%. For ERCP, minimum procedural volumes ranged from 100 to 300 with selective duct cannulation success rate of 80 % to 90 %. Guidelines also reported on flexible sigmoidoscopy, capsule endoscopy, and endoscopic ultrasound. Conclusions While some metrics such as ADR were relatively consistent among societies, there was substantial variation among societies with respect to procedural volume and KPI statements.

Abstract
BACKGROUND Developing effective gastrointestinal (GI) bleeding animal models is necessary to advance endoscopic hemostasis methods and train endoscopists on their use. Our aim, therefore, was to develop an effective and safe porcine GI bleeding model in the stomach and colon of large and small-sized oozing-type ulcers. METHODS Gastric and colonic bleeding ulcers were created using either a hybrid endoscopic submucosal dissection (ESD) technique or a cap-assisted endoscopic mucosal resection (EMR-C) technique in 14 pigs. Prior to ulcer creation, animals were treated with either oral apixaban or intravenous (IV) unfractionated heparin anticoagulation in combination with clopidogrel and aspirin. The primary outcome was the technical success of inducing oozing-type Forrest Ib bleeding ulcers. Secondary outcomes included ulcer diameter, number, creation time and the number of complications associated with each technique. RESULTS Using hybrid ESD and IV heparin anticoagulation, bleeding was observed in 21/23 (91.3%) gastric ulcers and 6/7 (85.7%) colonic ulcers created. The mean diameter and ulcer creation time were 2.3 ± 0.3 cm and 5.3 ± 0.5 min, respectively, for gastric ulcers and 2.2 ± 0.4 cm and 4.06 ± 0.6 min, respectively, for colonic ulcers. Using EMR-C and IV heparin anticoagulation, bleeding was observed in 14/15 (93.3%) gastric ulcers and 6/6 (100%) colonic ulcers created. The mean diameter and ulcer creation time were 0.8 ± 0.2 cm and 2.1 ± 0.5 min, respectively, for gastric ulcers and 0.7 ± 0.2 cm and 1.7 ± 0.3 min, respectively, for colonic ulcers. None of the ulcers created in animals anticoagulated with apixaban developed bleeding. None of the 14 pigs developed any complications. CONCLUSION We have demonstrated the effectiveness and safety of a porcine GI bleeding model utilizing IV heparin anticoagulation and either hybrid ESD or EMR-C techniques to create oozing-type bleeding ulcers in the stomach and colon with customizable size.

Abstract
IntroductionJoint Advisory Group (JAG) certification in endoscopy is awarded when trainees attain minimum competency standards for independent practice. A national evidence-based review was undertaken to update standards for training and certification in flexible sigmoidoscopy (FS).MethodsA modified Delphi process was conducted between 2019 and 2020 with multisociety representation from experts and trainees. Following literature review and Grading of Recommendations, Assessment, Development and Evaluations appraisal, recommendation statements on FS training and certification were formulated and subjected to anonymous voting to obtain consensus. Accepted statements were peer-reviewed by national stakeholders for incorporation into the JAG FS certification pathway.ResultsIn total, 41 recommendation statements were generated under the domains of: definition of competence (13), acquisition of competence (17), assessment of competence (7) and postcertification support (4). The consensus process led to revised criteria for colonoscopy certification, comprising: (A) achieving key performance indicators defined within British Society of Gastroenterology standards (ie, rectal retroversion >90%, polyp retrieval rate >90%, patient comfort <10% with moderate-severe discomfort); (B) minimum procedure count ≥175; (C) performing 15+ procedures over the preceding 3 months; (D) attendance of the JAG Basic Skills in Lower gastrointestinal Endoscopy course; (E) satisfying requirements for formative direct observation of procedural skill (DOPS) and direct observation of polypectomy skill (SMSA level 1); (F) evidence of reflective practice as documented on the JAG Endoscopy Training System reflection tool and (G) successful performance in summative DOPS.ConclusionThe UK standards for training and certification in FS have been updated to support training, uphold standards in FS and polypectomy, and provide support to the newly independent practitioner.

Abstract
IntroductionIn the UK, endoscopy certification is awarded when trainees attain minimum competency standards for independent practice. A national evidence-based review was undertaken to update and develop standards and recommendations for colonoscopy training and certification.MethodsUnder the oversight of the Joint Advisory Group (JAG), a modified Delphi process was conducted between 2019 and 2020 with multisociety expert representation. Following literature review and Grading of Recommendations, Assessment, Development and Evaluations appraisal, recommendation statements on colonoscopy training and certification were formulated and subjected to anonymous voting to obtain consensus. Accepted statements were peer reviewed by JAG and relevant stakeholders for incorporation into the updated colonoscopy certification pathway.ResultsIn total, 45 recommendation statements were generated under the domains of: definition of competence (13), acquisition of competence (20), assessment of competence (8) and postcertification support (4). The consensus process led to revised criteria for colonoscopy certification, comprising: (1) achieving key performance indicators defined within British Society of Gastroenterology standards (ie, unassisted caecal intubation rate >90%, rectal retroversion >90%, polyp detection rate >15%+, polyp retrieval rate >90%, patient comfort <10% with moderate–severe discomfort); (2) minimum procedure count 280+; (3) performing 15+ procedures over the preceding 3 months; (4) attendance of the JAG Basic Skills in Colonoscopy course; (5) terminal ileal intubation rates of 60%+ in inflammatory bowel disease; (6) satisfying requirements for formative direct observation of procedure skills (DOPS) and direct observation of polypectomy skills (Size, Morphology, Site, Access (SMSA) level 2); (7) evidence of reflective practice as documented on the JAG Endoscopy Training System reflection tool; (8) successful performance in summative DOPS.ConclusionThe UK standards for training and certification in colonoscopy have been updated, culminating in a single-stage certification process with emphasis on polypectomy competency (SMSA Level 2+). These standards are intended to support training, improve standards of colonoscopy and polypectomy, and provide support to the newly independent practitioner.

Colonoscopy quality improvement after initial training: A cross-sectional study of intensive short-term training. Endosc Int Open 2023; 11:E117-E127. [PMID: 36712907 PMCID: PMC9879657 DOI: 10.1055/a-1994-6084] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Accepted: 12/06/2022] [Indexed: 12/12/2022] Open
Abstract
Background and study aims High-quality is crucial for the effectiveness of colonoscopy and can be achieved by high-quality training and verified with assessment of key performance indicators (KPIs) for colonoscopy such as cecum intubation rate (CIR), adenoma detection rate (ADR) and adequate polyp resection. Typically, trainees achieve adequate CIR after 275 procedures, but little is known about learning curves for KPIs after initial training. Methods This cross-sectional study includes work-up colonoscopies after a positive screening test with fecal occult blood testing (FIT) or sigmoidoscopy, performed by either trainees after 300 training colonoscopies or by consultants. Outcome measures were KPIs. We assessed inter-endoscopist variation in trainees and learning curves for trainees as a group. We also compared KPIs for trainees and consultants as a group. Results Data from 6,655 colonoscopies performed by 21 trainees and 921 colonoscopies performed by 17 consultants were included. Most trainees achieved target standards for main KPIs. With time, trainees shortened cecum intubation time and withdrawal time without decreasing their ADR, reduced the proportion of painful colonoscopies, and increased the adequate polyp resection rate (all P < 0.01). Compared to consultants, trainees had higher CIR (97.7 % vs. 96.3 %, P = 0.02), ADR after positive FIT (57.6 % vs. 50.3 %, P < 0.01), and proximal ADR after sigmoidoscopy screening (41.1 % vs. 29.8 %; P < 0.01), higher adequate polyp resection rate (94.9 % vs. 93.1 %, P = 0.01) and fewer serious adverse events (0.65 % vs. 1.41 %, P = 0.02). Conclusions Trainees performed high-quality colonoscopies and achieved international target standards. Several KPIs continuously improved after initial training. Trainees outperformed consultants on several KPIs.

Abstract
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.

Abstract
BACKGROUND The reperfused human cadaver is a validated simulator for surgery. We aimed to use it as a colonoscopy simulator. METHODS Novices, intermediates and skilled participants in gastrointestinal endoscopy were included. They performed one colonoscopy on a reperfused human cadaver and reaching rates, time, and length needed to reach anatomical landmarks were reported for construct validity analysis. We also assessed our model realism (SRS survey), educational content (CVS survey) and task load (NASA-TLX index). Score items were collected and defined as "favorable" when items were rated ≥ 5/7 with an inter-quartile range (IQR) overlapping four, and "very favorable" when rated ≥ 5/7 with an IQR excluding four (neutral). Primary endpoints were the rectosigmoid junction (RSJ) reaching rate and the descending colon (DC) reaching time. Secondary objectives were SRS, CVS and NASA-TLX questionnaire results. RESULTS A total of 11 skilled participants, 5 intermediates and 8 novices were included. Skilled participants reached RSJ more often than novice and intermediary groups, respectively, 100%, 80% and 75% without differing significantly. They reached DC more frequently (100% for skilled, 80% for intermediates and 50% for novices, p = 0.018). The median time to reach RSJ (59, 272 and 686 s for skilled, intermediates and novices group, respectively) and DC (90, 534 and 1360 s for skilled, intermediates and novices) was significantly shorter for skilled participants (both p < .01). Nineteen out of the 22 items composing the realism survey obtained "very favorable" and "favorable" scores. Educational content was designated as "very favorable". Mental, physical, and technical demands were gradually higher the lower the initial level of experience. CONCLUSIONS Reperfused human cadaver model has the potential to be valid simulation tool for diagnostic colonoscopy training.

Abstract
BACKGROUND Endoscopic evaluation of the stomach is essential for preoperative planning and post-surgical surveillance for various diseases of the stomach, including malignancy. The gastroscopy education program for surgeons is currently in its infancy and is not systematically organized in Korea. This study aimed to introduce the first systematic gastroscopy education program for surgeons in Korea. METHODS The gastroscopy education program entitled "Gastroscopy School for Surgeons (GSS)" comprised of theoretical education, dry lab hands-on training, and clinical practice. All participants were beginners without any gastroscopy experience. Clinical practice started after the completion of the theoretical and dry lab training. The gastroscopy practices utilized simple luminal observation, biopsy, localization using clips or dye injection, and limited therapeutic gastroscopy. The educational performances and surveys from 33 participants were analyzed. RESULTS The participants consisted of surgical residents, general surgeons, gastrointestinal-specialized surgeons, and physicians. Participants performed a total of 2,272 gastroscopies, 2,008 of which were post-gastrectomy cases. Currently, of the 33 participants, 7 (21.2%) of the participants performed gastroscopy regularly, and 7 (21.2%) occasionally. According to the self-reported survey, one participant assessed their current gastroscopic technique to be at the expert level, and 25 (75.8%) at a proficient level. All participants considered gastroscopy education for surgeons to be necessary, and 28 (84.8%) stated that systematic education is not currently provided in Korea. CONCLUSION We introduced the first systematic gastroscopy education program for surgeons in Korea, namely the GSS, which is practical and meets clinical needs. More training centers are needed to expand gastroscopy training among Korean surgeons.

[PMID: 36186944 PMCID: PMC9516469 DOI: 10.4253/wjge.v14.i9.512] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Revised: 07/03/2022] [Accepted: 08/16/2022] [Indexed: 02/05/2023] Open
Abstract
Simulation-based mastery learning (SBML) is an emerging form of competency-based training that has been proposed as the next standard method for procedural task training, including that in gastrointestinal endoscopy. Current basic gastrointestinal endoscopy training relies on the number of procedures performed, and it has been criticized for its lack of objective standards that result in variable skills among trainees and its association with patient safety risk. Thus, incorporating simulators into a competency-based curriculum seems ideal for gastrointestinal endoscopy training. The curriculum for SBML in gastrointestinal endoscopy is currently being developed and has promising potential to translate into the clinical performance. Unlike the present apprenticeship model of “see one, do one, teach one,” SBML integrates a competency-based curriculum with specific learning objectives alongside simulation-based training. This allows trainees to practice essential skills repeatedly, receive feedback from experts, and gradually develop their abilities to achieve mastery. Moreover, trainees and trainers need to understand the learning targets of the program so that trainees can focus their learning on the necessary skills and trainers can provide structured feedback based on the expected outcomes. In addition to learning targets, an assessment plan is essential to provide trainees with future directions for their improvement and ensure patient safety by issuing a passing standard. Finally, the SBML program should be planned and managed by a specific team and conducted within a developed and tested curriculum. This review discusses the current state of gastrointestinal endoscopy training and the role of SBML in that field.

Abstract
Background and study aims Operator competency is essential for esophagogastroduodenoscopy (EGD) quality, which makes appropriate training with a final test important. The aims of this study were to develop a test for assessing skills in performing EGD, gather validity evidence for the test, and establish a credible pass/fail score. Methods An expert panel developed a practical test using the Simbionix GI Mentor II simulator (3 D Systems) and an EGD phantom (OGI 4, CLA Medical) with a diagnostic (DP) and a technical skills part (TSP) for a prospective validation study. During the test a supervisor measured: 1) total time; 2) degree of mucosal visualization; and 3) landmarks and pathology identification. The contrasting groups standard setting method was used to establish a pass/fail score. Results We included 15 novices (N), 10 intermediates (I), and 10 experienced endoscopists (E). The internal structure was high with a Cronbach's alpha of 0.76 for TSP time consumption and 0.74 for the identification of landmarks. Mean total times, in minutes, for the DP were N 15.7, I 11.3, and E 7.0, and for TSP., they were N 7.9, I 8.9, and E 2.9. The total numbers of identified landmarks were N 26, I 41, and E 48. Mean visualization percentages were N 80, I 71, and E 71. A pass/fail standard was established requiring identification of all landmarks and performance of the TSP in < 5 minutes. All experienced endoscopists passed, while none of the endoscopists in the other categories did. Conclusions We established a test that can distinguish between participants with different competencies. This enables an objective and evidence-based approach to assessment of competencies in EGD.

Abstract
Background A previous study suggested that psychomotor training improves the performance on colonoscopy. Since then, newer exercises have been included in the latest generation of GI Mentor®. In order to optimize a colonoscopy training program, we aimed to determine the impact of 3 virtual exercises in simulated colonoscopy skills. Methods This was a prospective and randomized study. Nineteen residents completed a pre-training questionnaire and a colonoscopy trial before randomization in a study group (n = 10) that performed three exercises (Endobubble I, Navigation I, and Mucosal Evaluation I) until they achieved expert level, and a control group (n = 9). Both groups performed 10 repetitions of a simulated colonoscopy and were assessed on a final case. Learning curves and skills transfer were assessed by four parameters: mucosal surface examined (%), time to reach the cecum (s), screening efficiency (%), and time the patient was in pain (%). We also evaluated the construct validity for the exercises. Results Construct validity was confirmed for Endobubble I and verified in Navigation I (experts were faster than novices; 5 vs. 7 s, p = 0.040), but not for Mucosal Evaluation I. Analyzing the learning curves and performance in the 10 repetitions, the study group reached the cecum faster (278 vs. 356 s, p = 0.035) and achieved a higher screening efficiency (83% vs. 75%, p = 0.019). Concerning skills transfer, the control group took longer to reach the cecum (241 vs. 292 s, p = 0.021) and the percentage of time the patient was in pain was higher (6% vs. 9%, p = 0.021). General performances of the study group had smaller interquartile variations. Conclusion Psychomotor training has a significant impact on the homogeneous acquisition and assimilation of colonoscopy skills. Endobubble I and Navigation I should be considered in the training programs for novices.

Abstract
BACKGROUND In France, it is mandatory that gastroenterology fellows have mastered the basic level of endoscopy by the end of training. The aim of this study was to assess improvement in the quality of fellows' endoscopy training in France during the last four years. METHODS All fellows in France in training were eligible for participation. A 21-item questionnaire was sent out. The primary outcome was the completion by fourth year fellows of all the number of procedures recommended. Results were compared with those of a 2016 survey. RESULTS Two-hundred-and-sixty-five fellows responded to the survey. The participation rate was 47.0%. The mean age was 27.3 ± 1.0 years and 56.4% were female. Access to theoretical courses (63.7% vs. 30.6%, p < 0.001) and simulation-based training (virtual reality simulator: 58.4% vs. 28.2%, p < 0.001, animal models: 29.4% vs. 17.2%, p < 0.001) was significantly higher in 2020. Although the number of procedures did not increase, significantly higher perception of skill acquisition in colonoscopy as well as diminished pressure to advance procedures were noted. CONCLUSION Access to theoretical courses and simulation-based training and perceived acquisition of numerous skills has gotten better. However, the quality of training in endoscopy still needs improvement.

Abstract
INTRODUCTION Training and quality assurance in oesophagogastroduodenoscopy (OGD) is important to ensure competent practice. A national evidence-based review was undertaken to update and develop standards and recommendations for OGD training and certification. METHODS Under the oversight of the Joint Advisory Group (JAG), a modified Delphi process was conducted with stakeholder representation from British Society of Gastroenterology, Association of Upper Gastrointestinal Surgeons, trainees and trainers. Recommendations on OGD training and certification were formulated following literature review and appraised using Grading of Recommendations Assessment, Development and Evaluation. These were subjected to electronic voting to achieve consensus. Accepted statements were incorporated into the updated certification pathway. RESULTS In total, 32 recommendation statements were generated for the following domains: definition of competence (4 statements), acquisition of competence (12 statements), assessment of competence (10 statements) and post-certification support (6 statements). The consensus process led to following certification criteria: (1) performing ≥250 hands-on procedures; (2) attending a JAG-accredited basic skills course; (3) attainment of relevant minimal performance standards defined by British Society of Gastroenterology/Association of Upper Gastrointestinal Surgeons of Great Britain and Ireland, (4) achieving physically unassisted D2 intubation and J-manoeuvre in ≥95% of recent procedures, (5) satisfactory performance in formative and summative direct observation of procedural skills assessments. CONCLUSION The JAG standards for diagnostic OGD have been updated following evidence-based consensus. These standards are intended to support training, improve competency assessment to uphold standards of practice and provide support to the newly-independent practitioner.

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 and study aims Studies have linked cecal intubation rate with adenoma detection rate; however, the direct association between technical performance during colonoscopy intubation and withdrawal has never been explored. Thus, it remains unclear whether gentle and efficient intubation predicts superior mucosal inspection. The aim of this study was to investigate the correlation between performance during intubation and withdrawal in a simulation-based setup. Methods Twenty-four physicians with various experience in colonoscopy performed twice on the Endoscopy Training System (ETS). Intubation skills were evaluated by assessing tasks on the ETS related to intubation (scope manipulation and loop management) and use of a computerized assessment tool called the 3D-Colonoscopy Progression Score (3D-CoPS). Diagnostic accuracy was defined by the number of polyps found during the ETS task of mucosal inspection. Pearson's correlations were calculated to explore associations between intubation skill and diagnostic accuracy. Results The correlation analysis between 3D-CoPS and number of polyps found during mucosal inspection revealed a weak and insignificant correlation (0.157, P = 0.3). Likewise, an insignificant correlation was seen between ETS intubation and number of polyps found (0.149, P = 0.32). Conclusions We found no evidence to support that technical performance during intubation is correlated with mucosal inspection performance in a simulation-based setting.

Abstract
Background and Aims: To investigate the impact of the computer-assisted system on esophagogastroduodenoscopy (EGD) training for novice trainees in a prospective randomized controlled trial. Methods: We have constructed a computer-aided system (CAD) using retrospective images based on deep learning which could automatically monitor the 26 anatomical landmarks of the upper digestive tract and document standard photos. Six novice trainees were allocated and grouped into the CAD group and control group. Each of them took the training course, pre and post-test, and EGD examination scored by two experts. The CAD group was trained with the assistance of the CAD system and the control group without. Results: Both groups achieved great improvements in EGD skills. The CAD group received a higher examination grading score in the EGD examination (72.83 ± 16.12 vs. 67.26 ± 15.64, p = 0.039), especially in the mucosa observation (26.40 ± 6.13 vs. 24.11 ± 6.21, p = 0.020) and quality of collected images (7.29 ± 1.09 vs. 6.70 ± 1.05). The CAD showed a lower blind spot rate (2.19 ± 2.28 vs. 3.92 ± 3.30, p = 0.008) compared with the control group. Conclusion: The artificial intelligence assistant system displayed assistant capacity on standard EGD training, and assisted trainees in achieving a learning curve with high operation quality, which has great potential for application. Clinical Trial Registration: This trial is registered at https:/clinicaltrials.gov/, number NCT04682821.

Abstract
Background Current evidence supports the use of virtual reality (VR) simulation-based training for novice endoscopists. However, there is still a need for a standardized induction programme which ensures sufficient preparation, with knowledge and basic skills, before their approach to patient-based training. We designed a structured progressive programme in upper endoscopy and colonoscopy and aimed to determine its impact on cognitive and technical performance. Methods Prospective, multicentre study, focused on "Endoscopy I, 2018," a course with a theoretical and a hands-on module (20 h) in the GI Mentor II®. Gastroenterology residents of the 1st year were enrolled. A pre-test and test were applied to evaluate the cognitive component, and a pre-training and post-training esophagogastroduodenoscopy (EGD) and colonoscopy VR cases were used to evaluate the technical component. The hands-on training included psychomotor exercises (Navigation I, Endobubble I), 4 EGD, and 4 colonoscopy VR cases. The metrics applied for technical skills evaluation were time to reach the second portion of duodenum (D2)/cecum (seconds), efficiency of screening (%), and time the patient was in pain (%). Results Twenty-three participants were included, majority female (67%), 26 ± 0.7 years old. Comparing the pre-test versus test, the cognitive score significantly improved (11/15 vs. 14/15; p < 0.001). Considering the technical assessment after training: in EGD, the time to D2 was significantly lower (193 vs. 63 s; p < 0.001), and the efficiency of screening significantly better (64 vs. 91%; p < 0.001); in colonoscopy, the time to reach the cecum was significantly lower (599 vs. 294 s; p = 0.001), the time the patient was in pain was significantly lower (27 vs. 10%; p = 0.005), and the efficiency of screening had a tendency towards improvement (50 vs. 68%; p = 0.062). Conclusion The proposed training curriculum in basic endoscopy for novices is aligned with international recommendations and demonstrated a significant impact on cognitive and technical skills learning achievements.

Abstract
Background Procedural simulation enhances early endoscopy training. Multiple commercial simulators are available; however, their application is limited by cost and poor user compliance. First-person "shooter" (FPS) video games are popular. In this study, we aimed to show that a novel in-house designed colonoscope controller used to play an FPS video game shares similar constructs with real-life endoscopy. Methodology Participants completed the first three levels on an FPS video game, Portal (Valve Corporation, Bellevue, WA), first using a conventional controller and then the modified endoscope controller. A total of 12 expert endoscopists and 12 surgical residents with minimal endoscopy experience were evaluated based on completion time, button presses, and hand motion analyses. Results Experts outperformed novices for completion time (expert: 944 seconds; novice: 1,515 seconds; p = 0.006) and hand movements (expert: 1,263.1; novice: 2,052.6; p = 0.004) in using the novel colonoscope controller. There was no difference in button presses or total path length traveled. Furthermore, performance did not differ using conventional game controls. Conclusions Experts outperformed novices using the endoscope but not the conventional controller with respect to the economy of movement and completion time. This result confirms that our endoscope-controlled video game shares similar paradigms with real-life endoscopy and serves as a first step toward creating a more enjoyable and cheaper alternative to commercially available endoscopy simulators.

Abstract
The European Society of Gastrointestinal Endoscopy (ESGE) has recognized the need to formalize and enhance training in endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS). This manuscript represents the outcome of a formal Delphi process resulting in an official Position Statement of the ESGE and provides a framework to develop and maintain skills in ERCP and EUS. This curriculum is set out in terms of the prerequisites prior to training; recommended steps of training to a defined syllabus; the quality of training; and how competence should be defined and evidenced before independent practice. 1: Trainees should be competent in gastroscopy prior to commencing training. Formal training courses and the use of simulation in training are recommended. 2: Trainees should keep a contemporaneous logbook of their procedures, including key performance indicators and the degree of independence. Structured formative assessment is encouraged to enhance feedback. There should be a summative assessment process prior to commencing independent practice to ensure there is robust evidence of competence. This evidence should include a review of a trainee's procedure volume and current performance measures. A period of mentoring is strongly recommended in the early stages of independent practice. 3: Specifically for ERCP, all trainees should be competent up to Schutz level 2 complexity (management of distal biliary strictures and stones > 10 mm), with advanced ERCP requiring a further period of training. Prior to independent practice, ESGE recommends that a trainee can evidence a procedure volume of > 300 cases, a native papilla cannulation rate of ≥ 80 % (90 % after a period of mentored independent practice), complete stones clearance of ≥ 85 %, and successful stenting of distal biliary strictures of ≥ 90 % (90 % and 95 % respectively after a mentored period of independent practice). 4: The progression of EUS training and competence attainment should start from diagnostic EUS and then proceed to basic therapeutic EUS, and finally to advanced therapeutic EUS. Before independent practice, ESGE recommends that a trainee can evidence a procedure volume of > 250 cases (75 fine-needle aspirations/biopsies [FNA/FNBs]), satisfactory visualization of key anatomical landmarks in ≥ 90 % of cases, and an FNA/FNB accuracy rate of ≥ 85 %. ESGE recognizes the often inadequate quality of the evidence and the need for further studies pertaining to training in advanced endoscopy, particularly in relation to therapeutic EUS.

Abstract
The COVID-19 pandemic is a unique challenge that has disrupted endoscopy training. Initial infection control measures aimed at protecting patients and staff meant nonessential endoscopic activity was suspended in many countries. The decrease in elective caseload from the pandemic also reduced training numbers during this period. While hands-on training took a backseat, more efforts were directed to didactic training of cognitive competencies. We review the literature describing the impact of COVID-19 on endoscopy training and summarize key measures aimed at mitigating this effect. These include leveraging on web-based didactic material and video-conferences, increased use of simulation and models to hone technical competencies, and a shift in focus from numbers-based accreditation to competency-based accreditation. While COVID-19 was hoped to be short-lived, it is clear the impact is long-lasting. Hence, it is crucial for training programs to take stock of how endoscopy training is evolving and use this opportunity to implement new paradigms into their endoscopic training curricula. COVID-19 might just be the catalyst that transforms endoscopy training into a new digital era.

Abstract
BACKGROUND Endoscopists use self-assessment to monitor the development and maintenance of their skills. The accuracy of these self-assessments, which reflects how closely one's own rating corresponds to an external rating, is unclear. METHODS In this narrative review, we critically examine the current literature on self-assessment in gastrointestinal endoscopy with the aim of informing training and practice and identifying opportunities to improve the methodological rigor of future studies. RESULTS In the seven included studies, the evidence regarding self-assessment accuracy was mixed. When stratified by experience level, however, novice endoscopists were least accurate in their self-assessments and tended to overestimate their performance. Studies examining the utility of video-based interventions using observation of expert benchmark performances show promise as a mechanism to improve self-assessment accuracy among novices. CONCLUSIONS Based on the results of this review, we highlight problematic areas, identify opportunities to improve the methodological rigor of future studies on endoscopic self-assessment and outline potential avenues for further exploration.

Abstract
Eye-tracking can help decode the intricate control mechanism in human performance. In healthcare, physicians-in-training require extensive practice to improve their healthcare skills. When a trainee encounters any difficulty in the practice, they will need feedback from experts to improve their performance. Personal feedback is time-consuming and subjected to bias. In this study, we tracked the eye movements of trainees during their colonoscopic performance in simulation. We examined changes in eye movement behavior during the moments of navigation loss (MNL), a signature sign for task difficulty during colonoscopy, and tested whether deep learning algorithms can detect the MNL by feeding data from eye-tracking. Human eye gaze and pupil characteristics were learned and verified by the deep convolutional generative adversarial networks (DCGANs); the generated data were fed to the Long Short-Term Memory (LSTM) networks with three different data feeding strategies to classify MNLs from the entire colonoscopic procedure. Outputs from deep learning were compared to the expert's judgment on the MNLs based on colonoscopic videos. The best classification outcome was achieved when we fed human eye data with 1000 synthesized eye data, where accuracy (91.80%), sensitivity (90.91%), and specificity (94.12%) were optimized. This study built an important foundation for our work of developing an education system for training healthcare skills using simulation.

Abstract
BACKGROUND Colonoscopy is a technically challenging procedure. The colonoscope is prone to forming loops in the colon, which can lead patient discomfort and even perforation. We hypothesized that expert endoscopists use techniques to avoid loop formation, identify and straighten loops earlier, and thus exert less force. METHODS Using a commercially available physical colon simulator model (Kyoto Kagaku), electromagnetic tracking markers (NDI Medical) were placed along the mobile segments of the colon (sigmoid, transverse) to measure the degree of displacement of the colon as the scope was advanced to the cecum. The colon model was set for each participant to simulate a redundant alpha loop in the sigmoid colon. Gastroenterology and surgical trainees and attendings were assessed. Demographic data were collected for each participant. RESULTS Seventy-five participants were enrolled in the study. There were 17 (22.7%) attending physicians, and 58 (77.3%) trainees. Attending physicians advanced the scope to the cecum faster. The mean time required for procedure completion was 360.5 s compared to 178.4 s for the trainee and attending groups respectively (mean difference: 182.1 s, 95% CI: 93.0, 269.7; p = 0.0002). Attending physicians exerted significantly lower mean colonic displacement than trainees. The mean colonic displacement was 79.8 mm for the trainee group and 57.9 mm for the attending group (mean difference: 21.9 mm, 95% CI: 2.6, 41.2; p = 0.04). Those who used torque steering caused lower maximum colonic displacement than those who used knob steering. CONCLUSION Attending physicians advance the scope during colonoscopy in a manner that results in significantly less colonic displacement than resident trainees. Although prior studies have shown a difference in force application between endoscopists and inexperienced students, ours is the first to differentiate across varying degrees of endoscopic skill. Future studies will define metrics for incorporation into endoscopic training curricula, focusing on techniques that encourage safety and comfort for patients.

Abstract
Background Competency-based gastrointestinal endoscopy training is concerned with outcomes of the learning experience. Feedback allows for trainees to achieve the expected outcomes. However, little is known about trainees’ experience of receiving feedback. Gaining understanding of their experience could help improve feedback practices. The study was conducted to explore what it means for adult gastroenterology trainees to receive feedback on their performance of endoscopy in the workplace. Methods An interpretative phenomenological approach was used. Individual semi-structured interviews were conducted with six trainees from three Canadian adult gastroenterology residency programs. Interviews were audio-recorded and transcribed verbatim for analysis. Analysis was conducted to identify the phenomenological themes across participants’ accounts of lived experience to provide an insight into the meaning of experiencing the studied phenomenon. Findings Three phenomenological themes of experience were identified: taking pauses, negotiating understandings and accepting asymmetry. Taking pauses allowed for participants to receive feedback on their performance of endoscopy. Participants needed to negotiate attending gastroenterologists’ different understandings of gastrointestinal endoscopy while carrying their own whenever feedback was provided. They had to accept the asymmetry between the roles of care provider and learner as well. Discussion The study has captured the uniqueness and the complexity of the lived experience of receiving feedback on the performance of endoscopy in the workplace from the perspective of study participants. The gained understanding of this experience has enabled the authors to suggest how attending gastroenterologists’ feedback practices may be improved.

Abstract
Background and Aims Prediction of intramucosal gastric cancer (GC) is a big challenge. It is not clear whether artificial intelligence could assist endoscopists in the diagnosis. Methods A deep convolutional neural networks (DCNN) model was developed via retrospectively collected 3407 endoscopic images from 666 gastric cancer patients from two Endoscopy Centers (training dataset). The DCNN model’s performance was tested with 228 images from 62 independent patients (testing dataset). The endoscopists evaluated the image and video testing dataset with or without the DCNN model’s assistance, respectively. Endoscopists’ diagnostic performance was compared with or without the DCNN model’s assistance and investigated the effects of assistance using correlations and linear regression analyses. Results The DCNN model discriminated intramucosal GC from advanced GC with an AUC of 0.942 (95% CI, 0.915–0.970), a sensitivity of 90.5% (95% CI, 84.1%–95.4%), and a specificity of 85.3% (95% CI, 77.1%–90.9%) in the testing dataset. The diagnostic performance of novice endoscopists was comparable to those of expert endoscopists with the DCNN model’s assistance (accuracy: 84.6% vs. 85.5%, sensitivity: 85.7% vs. 87.4%, specificity: 83.3% vs. 83.0%). The mean pairwise kappa value of endoscopists was increased significantly with the DCNN model’s assistance (0.430–0.629 vs. 0.660–0.861). The diagnostic duration reduced considerably with the assistance of the DCNN model from 4.35s to 3.01s. The correlation between the perseverance of effort and diagnostic accuracy of endoscopists was diminished using the DCNN model (r: 0.470 vs. 0.076). Conclusions An AI-assisted system was established and found useful for novice endoscopists to achieve comparable diagnostic performance with experts.

Abstract
As the clinical applications of endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) take more and more root in everyday practice and these endoscopic procedures become increasingly more complex and interventional with a higher chance for complications, the demand for expert bilio-pancreatic endoscopists continues to increase. In response to this growing need, specific postgraduate fellowships have been developed, however the standardization of training programs and the assessment of the achieved competence still remains an open debate. ERCP and EUS competency often requires training beyond the scope of a standard GI fellowship program, which lasts at least 1-2 years, and there are some differences in the way to face the issues of advanced bilio-pancreatic endoscopy training between Europe, America and the Asian regions. Today there is no role for the self-teaching of ERCP and EUS through trial and error without supervision and, in the near future, it is necessary to critically revise current training guidelines, to establish a standardized curriculum for advanced bilio-pancreatic endoscopists and to implement universally validated skill assessment tools, able to ensure constant and targeted feedback to trainees.

Abstract
INTRODUCTION Endoscopic Submucosal Dissection (ESD)was introduced in the West later than in the East. Our aim was to assess how Western endoscopists performing ESD have been trained and how they value animal models for training. MATERIAL AND METHODS An online survey regarding training in ESD was sent to Western endoscopists who published articles on advanced resection techniques. RESULTS From 279 endoscopists, 58 (21%) completed the questionnaire, of which 50 confirmed performance of clinical ESD. Endoscopists had a median of 15 years of endoscopic experience (IQR 9.75-20.25) and all of them were performing conventional EMR, before starting ESD. Prior to clinical ESD, 74% (n = 37) underwent training with ex vivo models, 84% (n = 42) with live animal models and 92% (n = 46) with at least, one of the two models. After starting clinical ESD, as trainers, 52% (n = 26) were involved with ex vivo and 60% (n = 30) with live animal models. Personal usefulness of ex vivo and live animal models was rated with a median of 9 (IQR 8-10) and 10 (IQR 8-10), out of 10, respectively. Courses with ex vivo and live animal models were considered a prerequisite before clinical practice by 84% (n = 42) and 78% (n = 39), respectively. CONCLUSIONS Western endoscopists have extensive endoscopic experience before starting ESD. The majority had pre-clinical training with ex vivo and live animal models and more than half are acting as trainers of other endoscopists with these models. Animal models are considered very useful and deemed a prerequisite before clinical practice by the majority of the endoscopists.

Training Simulators for Gastrointestinal Endoscopy: Current and Future Perspectives. Cancers (Basel) 2021; 13:cancers13061427. [PMID: 33804773 PMCID: PMC8004017 DOI: 10.3390/cancers13061427] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Revised: 03/11/2021] [Accepted: 03/16/2021] [Indexed: 12/11/2022] Open
Abstract
Simple Summary Over the last decades, visual endoscopy has become a gold standard for the detection and treatment of gastrointestinal cancers. However, mastering endoscopic procedures is complex and requires long hours of practice. In this context, simulation-based training represents a valuable opportunity for acquiring technical and cognitive skills, suiting the different trainees’ learning pace and limiting the risks for the patients. In this regard, the present contribution aims to present a critical and comprehensive review of the current technology for gastrointestinal (GI) endoscopy training, including both commercial products and platforms at a research stage. Not limited to it, the recent revolution played by the technological advancements in the fields of robotics, artificial intelligence, virtual/augmented reality, and computational tools on simulation-based learning is documented and discussed. Finally, considerations on the future trend of this application field are drawn, highlighting the impact of the most recent pandemic and the current demographic trends. Abstract Gastrointestinal (GI) endoscopy is the gold standard in the detection and treatment of early and advanced GI cancers. However, conventional endoscopic techniques are technically demanding and require visual-spatial skills and significant hands-on experience. GI endoscopy simulators represent a valid solution to allow doctors to practice in a pre-clinical scenario. From the first endoscopy mannequin, developed in 1969, several simulation platforms have been developed, ranging from purely mechanical systems to more complex mechatronic devices and animal-based models. Considering the recent advancement of technologies (e.g., artificial intelligence, augmented reality, robotics), simulation platforms can now reach high levels of realism, representing a valid and smart alternative to standard trainee/mentor learning programs. This is particularly true nowadays, when the current demographic trend and the most recent pandemic demand, more than ever, the ability to cope with many patients. This review offers a broad view of the technology available for GI endoscopy training, including platforms currently in the market and the relevant advancements in this research and application field. Additionally, new training needs and new emerging technologies are discussed to understand where medical education is heading.

Abstract
Background and study aims Current data show that traditional training methods in endoscopic retrograde cholangiopancreatography (ERCP) fall short of producing competent trainees. We aimed to evaluate whether a novel approach to simulator-based training might improve the learning curve for novice endoscopists training in ERCP. Methods We conducted a multicenter, randomized controlled trial using a validated mechanical simulator (the Boškoski-Costamagna trainer). Trainees with no experience in ERCP received either standard cannulation training or motion training before undergoing standard cannulation training on the mechanical simulator. Trainees were timed and graded on their performance in selective cannulation of four different papilla configurations. Results Thirty-six trainees (16 in the motion training group, 20 in the standard group) performed 720 timed attempts at cannulating the bile duct on the simulator. Successful cannulation was achieved in 698 of 720 attempts (96.9 %), with no significant difference between the two study groups ( P = 0.37). Trainees in the motion training group had significantly lower median cannulation times compared to the standard group (36 vs. 48 seconds, P = 0.001) and better technical performance on the first papilla type ( P = 0.013). Conclusions Our findings suggest that motion training could be an innovative method aimed at accelerating the learning curve of novice trainees in the early phase of their training. Future studies are needed to establish its role in ERCP training programs.

Identifying technical skills and clinical procedures in surgery for a simulation-based curriculum: a national general needs assessment. Surg Endosc 2021; 36:47-56. [PMID: 33398569 DOI: 10.1007/s00464-020-08235-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Accepted: 12/03/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND The efficacy of simulation-based training in surgical education is well known. However, the development of training programs should start with problem identification and a general needs assessment to ensure that the content is aligned with current surgical trainee needs. The objective of the present study is to identify the technical skills and clinical procedures that should be included in a simulation-based curriculum in general surgery. METHODS A national, three-round Delphi process was conducted to achieve consensus on which technical skills and clinical procedures should be included in a simulation-based curriculum in general surgery. In total, 87 key opinion leaders were identified and invited to the study. RESULTS Round 1 of the Delphi process had a response rate of 64% (56/87) and a total of 245 suggestions. Based on these suggestions, a consolidated list of 51 technical skills or clinical procedures was made. The response rate in Delphi round 2 was 62% (54/87) resulting in a pre-prioritized order of procedures for round 3. The response rate in Delphi round 3 was 65% (35/54). The final list included 13 technical skills and clinical procedures. Training was predominantly requested within general open surgical skills, laparoscopic skills, and endoscopic skills, and a few specific procedures such as appendectomy and cholecystectomy were included in the final prioritized list. CONCLUSION Based on the Delphi process 13 technical skills and clinical procedures were included in the final prioritized list, which can serve as a point of departure when developing simulation-based training in surgery.

Abstract
Introduction The acquisition of sensorimotor skills, so-called "technical skills", plays an essential part in the professional and continuing educational training of medical and nursing staff. Facilities turn to simulator training to promote the safe and accurate performance of endoscopic examinations. Thus, this study aimed to develop and pilot-test a corresponding assessment instrument to monitor necessary sensorimotor or "technical" skills of the examiner for a safe percutaneous endoscopic gastrostomy (AS-PEG). Materials and Methods Instrument development and pilot validation involved four stages: identification of potential items and initial draft of the AS-PEG; expert panel with 11 experts (content validity index [CVI] calculated); empirical validation using a quasi-experimental intervention on simulators; revision of the pilot AS-PEG taking expert assessment, and empirical testing into consideration. Results The initial instrument yielded 13 categories and 44 items describing the PEG procedure. Experts rated 30 out of 44 items (68%) extremely or very important for the safety of the puncture of the stomach. Initial item-CVIs ranged from 0.00 to 1.00; scale-CVI was 0.61. Twenty-four trainees (7 physicians, 17 nurses) participated in the pilot simulation study. On average, 8:25 min were required for PEG placement (min-max 5:59-13:38 min, SD = 1:43). The revised AS-PEG version was reduced to 14 items with a range of the item CVI from 0.8 to 1.0, and a scale-CVI of 0.90. Conclusion The AS-PEG instrument facilitates the evaluation of sensorimotor skills during percutaneous gastric puncture procedures within the context of PEG placement, across professions and without relating to the number of procedures previously performed. The instrument is economical and shows satisfying content validity.

Abstract
BACKGROUND Virtual reality simulation in gastrointestinal endoscopy is an educational tool that allows repetitive instruction in a non-patient care environment. AIM To determine the impact of a virtual endoscopy training curriculum applying an objective pre- and post-training analysis on trainee endoscopists. METHODS A before-after training study was carried out. Subjects were first year fellows of gastroenterology, who completed a questionnaire and then performed two pre-training simulated cases. The virtual endoscopy training curriculum consisted of an 8-h workday utilizing two GI MENTOR™ in a specialized clinical simulation center. After the training, all subjects completed the same two cases they did in the pre-training. Pre- and post-training results' comparisons were made by paired t test. RESULTS Totally, 126 subjects were included (mean age 30 years, 61% female). A significant improvement from pre- to post-training was observed in psychomotor skills (total time, percentage, and number of balloons exploded) and endoscopic skills (cecal intubation time, percentage of examined mucosa, and efficacy of screening). There was also an improvement in the quality of the endoscopic study; percentage of examined mucosa over 85% showed a significant improvement post-training with an adjusted OR of 2.72 (95% CI 1.51-4.89, p = 0.001). CONCLUSIONS Virtual endoscopy training curriculum produces a significant improvement in the trainee endoscopists performance and their psychomotor skills and introduces the concept of a quality endoscopic study in a non-patient, risk-free environment.
