Competence in Endoscopic Ultrasound and Endoscopic Retrograde Cholangiopancreatography, From Training Through Independent Practice

Training and quality indicators in interventional endoscopic ultrasound

Endoscopic ultrasound (EUS) has transformed the landscape of minimally invasive gastrointestinal procedures, necessitating specialized training for proficiency in interventional EUS (iEUS). This study evaluates the effectiveness of iEUS training, focusing on learning curves, success rates, and the associated risks in various procedures, aiming to recommend practices for standardizing training and ensuring competency. Key metrics such as procedure type, learning curve for proficiency, success rates, and risk of adverse events were analyzed to establish benchmarks for training programs. Proficiency in pancreatic fluid collection drainage was achieved after 20-30 procedures, with a 100% success rate and a complication rate ranging from 1.5 to 80%. Gallbladder drainage required 19 cases to reach an 86% success rate, with adverse events reported in 19% of cases. Choledocoduodenostomy mastery was observed after approximately 100 cases, with postintervention pancreatitis affecting 5.3-6.6% of all cases. Hepaticogastrostomy showed a 93% success rate after 33 cases, with a 24.8% adverse event rate. Hepaticoenterostomy reached 100% success beyond the 40th patient, with a 20% rate of postsurgical strictures. Pancreatic duct drainage achieved 89% technical and 87% clinical success after 27 cases, with 12-15% adverse events. Gastro-enteric anastomosis required 25 cases for proficiency and approximately 40 cases for mastery, with 5.5% immediate and 1% late adverse events. iEUS training outcomes vary significantly across different procedures, highlighting the importance of structured, procedure-specific training programs to achieve proficiency. These findings provide a foundation for developing universal competency benchmarks in iEUS, facilitating consistent and effective training worldwide.

Development of American Society for Gastrointestinal Endoscopy standards for training in advanced endoscopy within dedicated advanced endoscopy fellowship programs

BACKGROUND AND AIMS

Training in interventional endoscopy is offered by nonaccredited advanced endoscopy fellowship programs (AEFPs). The number of these programs has increased dramatically with a concurrent increase in the breadth and complexity of interventional endoscopy procedures. Accreditation is governed by competency-based education, yet what constitutes a "high-quality" nonaccredited AEFP has not been defined. Using an evidence-based consensus process, we aimed to establish standards for AEFPs.

METHODS

The RAND UCLA appropriateness method, a well-described modified Delphi process to develop quality indicators, was used. A task force established by the American Society for Gastrointestinal Endoscopy drafted potential quality indicators (structure, process, and outcome) in 6 categories: activity preceding training; structure of AEFPs; training in ERCP, EUS, and EMR; and luminal stent placement. Three rounds of iterative feedback from 20 experts were conducted. Round 0 involved discussion of project details. In round 1, experts independently ranked proposed quality indicators on a 9-point interval scale ranging from highly inappropriate (1) to highly appropriate (9). Next, proposed quality indicators were discussed and reworded in a group meeting followed by round 2, in which experts independently reranked proposed quality indicators and provided benchmarks (when applicable). The median score for each quality indicator was calculated. Mean absolute deviation from the median was calculated, and appropriateness of potential quality indicators was assessed using the BIOMED concerted action on appropriateness definition, P value method, and interpercentile range adjusted for symmetry definition. A quality indicator was deemed appropriate if the median score was ≥7 and met criteria for appropriateness using all 3 defined statistical methods.

RESULTS

Of 89 proposed quality indicators, 37 statements met criteria as appropriate for a quality indicator (activity preceding training, 2; structure of AEFPs, 10; training in ERCP, 7; training in EUS, 8; training in EMR, 7; luminal stent placement, 3). Minimum thresholds were defined for 19 relevant quality indicators for number of trainers, procedures during fellowship, and procedures before assessment of competence. Among the final appropriate quality indicators were that all trainees should undergo qualitative and quantitative competence assessments using validated tools at least quarterly with documented feedback throughout the training period and that trainees should track outcomes and relevant quality metrics for specific procedures.

CONCLUSIONS

This consensus process using validated methodology established standards for an AEFP in an effort to ensure adequate training in the most commonly taught interventional endoscopic procedures (ERCP, EUS, EMR, and luminal stent placement) during fellowship. An important component of an AEFP is the use of competency-based assessments that are compliant with the Accreditation Council for Graduate Medical Education's Next Accreditation System, with the goal of ensuring that trainees achieve specific milestones in their progression to achieving cognitive and technical competency.

Vade Mecum in ERCP, a roadmap to success: Tips from experts for excelling in ERCP

Background and study aims Training in endoscopic retrograde cholangiopancreatography (ERCP) is operator-dependent and traditionally, the apprenticeship model, in which experts are considered to be role models, has been adopted for it. The aim of this study was to develop a practical guide compiling tips from experts to help guide trainees to succeed in ERCP. Methods A web-based survey was created to understand the professional development of ERCP experts, the investments they made, the obstacles they overcame, and the quotes that guided their professional life. ERCP experts worldwide were invited to participate. Results Fifty-three experts (of 71; 74.6%) from 24 countries answered the survey. Experts started ERCP training early (average age 31 years; range, 24-52 years) and it often was combined with training for endoscopic ultrasound. A long training period (average 21 months; range, 3-120 months) was needed to achieve competence, frequently in another department, and it was commonly complemented with research in the field (76.5%). "Time and practice" were the most worthwhile investments they made to achieve success. "Sports" were an area outside endoscopy frequently considered to be important to acquire the skills necessary to excel in ERCP. "Lack of dedicated time for training" and "peer competition" were the biggest obstacles the experts faced. Several pieces of advice were given to the experts, such as to be resilient, careful, patient, responsible, and hard-working. "Personal life" was mentioned as an undeniably crucial factor for achieving long-term success that should not be forgotten. Conclusions This survey is the first to provide insight regarding the professional trajectory of renowned ERCP experts worldwide, providing valuable recommendations to help trainees excel in ERCP.

Quality indicators of endoscopic ultrasound in the pancreatobiliary system: a brief review of current guidelines

Since its development, the use of endoscopic ultrasonography (EUS) in the pancreas and the biliary tract has become increasingly important. The accuracy of EUS varies depending on the experience of the endoscopist. Hence, quality control measures using appropriate indicators are required to reduce these variations. American Society for Gastrointestinal Endoscopy and European Society of Gastrointestinal Endoscopy have announced the EUS quality indicators. Here, we reviewed the quality indicators of the EUS procedure in the current published guidelines.

Curriculum for diagnostic endoscopic ultrasound training in Europe: European Society of Gastrointestinal Endoscopy (ESGE) Position Statement

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.

Training in basic gastrointestinal endoscopic procedures: a European Society of Gastrointestinal Endoscopy (ESGE) and European Society of Gastroenterology and Endoscopy Nurses and Associates (ESGENA) Position Statement

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.

Limited exposure to pancreatic ERCP during advanced endoscopy training impacts competence and performance in independent practice

BACKGROUND/OBJECTIVES

The impact of competency-based training programs on pancreatic endoscopic retrograde cholangiopancreatography (ERCP) performance remains unclear. This study aimed to describe the learning curves of pancreatic ERCP and subsequent performance during independent practice.

METHODS

This was a multicenter prospective cohort study involving advanced endoscopy trainees (AETs). In the 1st phase, trainees were assessed on every 5th ERCP using the ERCP and EUS Skills Assessment Tool (TEESAT). Cumulative sum (CUSUM) analysis of pancreatic ERCP evaluations was used to establish learning curves. During the 2nd phase (1st year of independent practice), now-graduated participants documented their performance on key ERCP quality indicators.

RESULTS

A total of 24 AETs (20 training programs) received sufficient evaluations for CUSUM analysis. Pancreatic ERCP accounted for 14.6 % (196/1339) of all ERCPs evaluated with 45 % of pancreatic ERCPs carrying a Grade 3 level of complexity. A minority of AETs (16.7 %) performed enough pancreatic ERCPs to generate meaningful learning curves with no AETs achieving competence in pancreatic cannulation, sphincterotomy, or stone clearance during Phase 1. In Phase 2, a total of 3620 ERCPs were performed, of which 281 (7.8 %) were pancreatic ERCPs. While the overall pancreatic duct cannulation rate was 92.2 %, the native papilla pancreatic duct cannulation rate was 85.7 %, which was below the recommended 90 % threshold.

CONCLUSIONS

Advanced endoscopy training offers a low level of exposure to pancreatic ERCP, which is mirrored in independent practice, highlighting the inadequate training in pancreatic ERCP. Given the complexity of pancreatic ERCP, novel strategies are warranted to improve training in pancreatic ERCP.

Impact and assessment of training models in interventional endoscopic ultrasound

Interventional endoscopic ultrasound (IEUS) has gained significant popularity in recent years because of its diagnostic and therapeutic capabilities. The proper training of endoscopists is critical to ensure safe and effective procedures. This review study aims to assess the impact of different training models on the competence of trainees performing IEUS. Eight studies that evaluated simulators for IEUS were identified in the medical literature. Various training models have been used, including the EASIE-R, Mumbai EUS, EUS Magic Box, EndoSim, Thai Association for Gastrointestinal Endoscopy model, and an ex vivo porcine model (HiFi SAM). The trainees underwent traditional didactic lectures, hands-on training using simulators, and direct supervision by experienced endoscopists. The effectiveness of these models has been evaluated based on objective and subjective parameters such as technical proficiency, operative time, diagnostic success, and participant feedback. As expected, the majority of skills were improved after the training sessions concluded, although the risk of bias is high in the absence of external validation. It is difficult to determine the ideal simulator among the existing ones because of the wide variation between them in terms of costs, reusability, design, fidelity of anatomical structures and feedback, and types of procedures performed. There is a need for a standardized approach for the evaluation of IEUS simulators and the ways skills are acquired by trainees, as well as a clearer definition of the key personal attributes necessary for developing a physician into a skilled endoscopist capable of performing basic and advanced therapeutic EUS interventions.

Endoscopic retrograde cholangiopancreatography training and education

Endoscopic retrograde cholangiopancreatography (ERCP) is an advanced endoscopic technique used to diagnose and treat biliary and pancreatic diseases. It is one of the most technically demanding endoscopic procedures. ERCP training programs must ensure trainees have adequate knowledge of the anatomy and physiology associated with biliopancreatic diseases. The variety of ERCP procedures included in training programs should provide sufficient basic training for novice trainees and advanced training for experienced endoscopists. The main endoscopic procedures should be trained in ascending order of difficulty. Incorporating models capable of simulating various clinical and anatomical conditions could provide an effective means of fulfilling training requirements, although they are not easily available due to expensive facilities and void of standard assessment. Competency assessment is crucial in ERCP training to ensure trainees can independently and safely perform ERCP. Because of the rapid advancement of diagnostic and therapeutic methods, postgraduate training is critical for ERCP practitioners. Once certificates are attained, practitioners are solely responsible for maintaining their competency, credentialing, and quality.

UK and Ireland Joint Advisory Group (JAG) consensus statements for training and certification in diagnostic endoscopic ultrasound (EUS)

BACKGROUND AND AIMS

International endoscopy societies vary in their approach for credentialing individuals in endoscopic ultrasound (EUS) to enable independent practice; however, there is no consensus in this or its implementation. In 2019, the Joint Advisory Group on GI Endoscopy (JAG) commissioned a working group to examine the evidence relating to this process for EUS. The aim of this was to develop evidence-based recommendations for EUS training and certification in the UK.

METHODS

Under the oversight of the JAG quality assurance team, a modified Delphi process was conducted which included major stakeholders from the UK and Ireland. A formal literature review was made, initial questions for study were proposed and recommendations for training and certification in EUS were formulated after a rigorous assessment using the Grading of Recommendation Assessment, Development and Evaluation tool and subjected to electronic voting to identify accepted statements. These were peer reviewed by JAG and relevant stakeholder societies before consensus on the final EUS certification pathway was achieved.

RESULTS

39 initial questions were proposed of which 33 were deemed worthy of assessment and finally formed the key recommendations. The statements covered four key domains, such as: definition of competence (13 statements), acquisition of competence (10), assessment of competence (5) and postcertification mentorship (5). Key recommendations include: (1) minimum of 250 hands-on cases before an assessment for competency can be made, (2) attendance at the JAG basic EUS course, (3) completing a minimum of one formative direct observation of procedural skills (DOPS) every 10 cases to allow the learning curve in EUS training to be adequately studied, (4) competent performance in summative DOPS assessments and (5) a period of mentorship over a 12-month period is recommended as minimum to support and mentor new service providers.

CONCLUSIONS

An evidence-based certification pathway has been commissioned by JAG to support and quality assure EUS training. This will form the basis to improve quality of training and safety standards in EUS in the UK and Ireland.

Impact of center and endoscopist ERCP volume on ERCP outcomes: a systematic review and meta-analysis

BACKGROUND AND AIMS

Endoscopist experience and center volume might be associated with ERCP outcomes, as in other fields of endoscopy and in surgery. An effort to assess this relationship is important to improve practice. This systematic review and meta-analysis aimed to evaluate these comparative data and to assess the impact of endoscopist and center volume on ERCP procedure outcomes.

METHODS

We performed a literature search in PubMed, Web of Science, and Scopus through March 2022. Volume classification included high- and low-volume (HV and LV) endoscopists and centers. The primary outcome was the impact of endoscopist and center volume on ERCP success. Secondary outcomes were the overall adverse event (AE) rate and the specific AE rate. The quality of the studies was assessed using the Newcastle-Ottawa scale. Data synthesis was obtained by direct meta-analyses using a random-effects model; results are presented as odds ratios (ORs) with 95% confidence intervals (CIs).

RESULTS

Of 6833 relevant publications, 31 studies met the inclusion criteria. Procedure success was higher among HV endoscopists (OR, 1.81; 95% CI, 1.59-2.06; I2 = 57%) and in HV centers (OR, 1.77; 95% CI, 1.22-2.57; I2 = 67%). The overall AE rate was lower for procedures performed by HV endoscopists (OR, .71; 95% CI, .61-.82; I2 = 38%) and in HV centers (OR, .70; 95% CI, .51-.97; I2 = 92%). Bleeding was less frequent in procedures performed by HV endoscopists (OR, .67; 95% CI, .48-.95; I2 = 37%) but did not differ based on center volume (OR, .68; 95% CI, .24-1.90; I2 = 89%). No statistical differences were detected concerning pancreatitis, cholangitis, and perforation rates.

CONCLUSIONS

HV endoscopists and centers provide higher ERCP success rates with fewer overall AEs, especially bleeding, compared with respective LV comparators.

Validity evidence for observational ERCP competency assessment tools: a systematic review

BACKGROUND : Assessment of competence in endoscopic retrograde cholangiopancreatography (ERCP) is critical for supporting learning and documenting attainment of skill. Validity evidence supporting ERCP observational assessment tools has not been systematically evaluated. METHODS : We conducted a systematic search using electronic databases and hand-searching from inception until August 2021 for studies evaluating observational assessment tools of ERCP performance. We used a unified validity framework to characterize validity evidence from five sources: content, response process, internal structure, relations to other variables, and consequences. Each domain was assigned a score of 0-3 (maximum score 15). We assessed educational utility and methodological quality using the Accreditation Council for Graduate Medical Education framework and the Medical Education Research Quality Instrument, respectively. RESULTS : From 2769 records, we included 17 studies evaluating 7 assessment tools. Five tools were studied for clinical ERCP, one for simulated ERCP, and one for simulated and clinical ERCP. Validity evidence scores ranged from 2 to 12. The Bethesda ERCP Skills Assessment Tool (BESAT), ERCP Direct Observation of Procedural Skills Tool (ERCP DOPS), and The Endoscopic Ultrasound (EUS) and ERCP Skills Assessment Tool (TEESAT) had the strongest validity evidence, with scores of 10, 12, and 11, respectively. Regarding educational utility, most tools were easy to use and interpret, and required minimal additional resources. Overall methodological quality (maximum score 13.5) was strong, with scores ranging from 10 to 12.5. CONCLUSIONS : The BESAT, ERCP DOPS, and TEESAT had strong validity evidence compared with other assessments. Integrating tools into training may help drive learners' development and support competency decision making.

ERCP-related adverse events: incidence, mechanisms, risk factors, prevention, and management

INTRODUCTION

Endoscopic retrograde cholangiopancreatography (ERCP) is a commonly performed procedure for pancreaticobiliary disease. While ERCP is highly effective, it is also associated with the highest adverse event (AE) rates of all commonly performed endoscopic procedures. Thus, it is critical that endoscopists and caregivers of patients undergoing ERCP have clear understandings of ERCP-related AEs.

AREAS COVERED

This narrative review provides a comprehensive overview of the available evidence on ERCP-related AEs. For the purposes of this review, we subdivide the presentation of each ERCP-related AE according to the following clinically relevant domains: definitions and incidence, proposed mechanisms, risk factors, prevention, and recognition and management. The evidence informing this review was derived in part from a search of the electronic databases PubMed, Embase, and Cochrane, performed on 1 May 20231 May 2023.

EXPERT OPINION

Knowledge of ERCP-related AEs is critical not only given potential improvements in peri-procedural quality and related care that can ensue but also given the importance of reviewing these considerations with patients during informed consent. The ERCP community and researchers should aim to apply standardized definitions of AEs. Evidence-based knowledge of ERCP risk factors should inform patient care decisions during training and beyond.

Analysis of the variation in learning curves for achieving competency in convex EUS training: a prospective cohort study using a standardized assessment tool

BACKGROUND AND AIMS

The need for mastering standard imaging techniques for convex EUS in the biliopancreatic regions has been increasing; however, large variations in the aptitude for achieving EUS competency hinder expert development. Therefore, we investigated the factors influencing the achievement of expert competency in EUS using a new assessment tool for multiple imaging items.

METHODS

Between January 2018 and February 2022, 3277 consecutive EUS procedures conducted by 5 beginners (EUS procedures <250), 7 intermediate trainees (250-749), and 2 experts (≥750) were prospectively evaluated. Immediately after each EUS procedure, the success or failure of imaging for each item was recorded using a newly developed EUS assessment tool that requires 17 items to be photographed. After correcting for missing values using multiple imputation, learning curves of EUS scores were created, and a competency was set based on expert scores. Finally, a comparative analysis between high and low performers was performed to extract factors influencing EUS scores.

RESULTS

Although 3 of 7 intermediates (43%; mean, 317 cases) achieved competency, none of the beginners achieved competency. During a comparative analysis, although no significant difference in the number of EUS procedures performed was observed between the high and low performers, the former had significantly higher scores in the written test (theoretical knowledge).

CONCLUSIONS

Our results showed that theoretical knowledge, rather than the number of EUS cases, may be a possible influencing factor for distinguishing high and low performers after treating 250 cases. (Clinical trial registration number: UMIN 000043271.).

Endoscopy and Pediatric Pancreatitis

Children and adolescents are increasingly impacted by pancreatic disease. Interventional endoscopic procedures, including endoscopic retrograde cholangiopancreatography) and endoscopic ultrasonography, are integral to the diagnosis and management of many pancreatic diseases in the adult population. In the past decade, pediatric interventional endoscopic procedures have become more widely available, with invasive surgical procedures now being replaced by safer and less disruptive endoscopic interventions.

Resection speed of endoscopic submucosal dissection according to the location of gastric neoplasia: a learning curve using cumulative sum analysis

BACKGROUND

There is few study evaluating the relationship between endoscopic submucosal dissection (ESD) resection speed and the lesion characteristics of gastric neoplasia. We investigated the learning curve of consecutive ESDs using cumulative sum (CUSUM) analysis.

METHODS

A total of 356 ESDs performed by a single endoscopist were grouped chronologically into three learning periods. The ESD procedure was defined to be fast when resection speed was > 9.0 cm²/hour. The CUSUM method was used to assess the number of ESDs required for achieving proficiency and mastery.

RESULTS

Mean resection speed was significantly faster in Phase III (15.1 cm²/hour) compared to those in Phase I (9.3 cm²/hour) and II (11.4 cm²/hour) (p < 0.001). Tumors in the stomach's upper and middle third location were significantly associated with difficulty in attaining the fast resection speed (odds ratios, 0.05 and 0.36) compared to the lower third location. The number of ESDs required to achieve a competency for fast resection was 15 for tumors in the lower third of the stomach and 98 for those in the upper/middle third location, respectively. In the lower third location of the tumor, the CUSUM curve revealed that 75 cases were needed to achieve proficiency and 174 cases to achieve mastery. However, mastery was not achieved in ESD for the upper/middle third tumor during the study period.

CONCLUSION

The time required to achieve relevant competency in gastric ESD depends on the tumor location.

Competence development of trainees performing short-type single-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography in patients with surgically altered anatomy

OBJECTIVES

This study aimed to evaluate the trainees' practice and learning curve in short-type single-balloon enteroscopy (short SBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) for patients with surgically altered anatomy (SAA) and determine how to train these trainees.

METHODS

The data of short SBE-assisted ERCP procedures between September 2011 and June 2021 were analyzed.

RESULTS

Three trainees and 180 cases were included in the analysis. Each trainee performed 60 cases between April 2016 and June 2021. The trainees' completion rate was 73.9% (95% confidence interval [CI], 66.8-80.1%). Adverse events occurred in 5.0% of cases (95% CI, 2.3-9.3%). The trainee who experienced colonoscopy and ERCP the most achieved better outcomes of enteroscopy success (reaching the target site) and trainee's completion rates than those of the others (P = .03 and .02, respectively). The learning curve for trainee's completion showed a significant improvement after 60 cases (P = .001). Multiple logistic regression analysis indicated that Roux-en-Y reconstruction was the factor affecting trainees' completion failure.

CONCLUSIONS

Short SBE-assisted ERCP trainees has a substantial learning curve. If trainees do not have much experience with colonoscopy and ERCP procedures, it may be beneficial for them to start performing short SBE-assisted ERCP procedures on non-Roux-en-Y reconstruction cases.

Learning curves in ERCP during advanced endoscopy training: a Canadian multicenter prospective study

Background and study aims  Growing emphasis on quality and patient safety has supported the shift toward competency-based medical education for advanced endoscopy trainees (AETs). In this study, we aimed to examine Canadian AETs learning curves and achievement of competence using an ERCP assessment tool with strong evidence of validity. Methods  This prospective study was conducted at five institutions across Canada from 2017-2018. Data on every fifth procedure performed by trainees were collected using the United Kingdom Joint Advisory Joint Advisory Group of Gastrointestinal Endoscopy (JAG) ERCP Direct Observation of Procedural Skills (DOPS) tool, which includes a four-point rating scale for 27 items. Cumulative sum (CUSUM) analysis was used to create learning curves for overall supervision ratings and ERCP DOPS items by plotting scores for procedures performed during training. Results  Eleven trainees who were evaluated for 261 procedures comprised our sample. The median number of evaluations by site was 49 (Interquartile range (IQR) 31-76) and by trainee was 15 (IQR 11-45). The overall cannulation rate by trainees was 82 % (241/261), and the native papilla cannulation rate was 78 % (149/191). All trainees achieved competence in the "overall supervision" domain of the ERCP DOPS by the end of their fellowship. Trainees achieved competency in all individual domains, except for tissue sampling and sphincteroplasty. Conclusions  Canadian AETs are graduating from fellowship programs with acceptable levels of competence for overall ERCP performance and for the most specific tasks. Learning curves may help identify areas of deficiency that may require supplementary training, such as tissue sampling.

The present and future of gastroenterology and hepatology: an international SWOT analysis (the GASTROSWOT project)

GASTROSWOT is a strategic analysis of the current and projected states of the different subspecialties in gastroenterology that aims to provide guidance for research, clinical, and financial planning in gastroenterology. We executed a consensus-based international strengths, weaknesses, opportunities, and threats (SWOT) analysis. Four general coordinators, six field coordinators, and 12 experts participated in the study. SWOTs were provided for the following fields: neurogastroenterology, functional gastrointestinal disorders, and upper gastrointestinal diseases; inflammatory bowel disease; pancreatology and biliary diseases; endoscopy; gastrointestinal oncology; and hepatology. The GASTROSWOT analysis highlights the following in the current state of the field of gastroenterology: the incidence and complexity of several gastrointestinal diseases, including malignancies, are increasing; the COVID-19 pandemic has affected patient care on several levels; and with the advent of technical innovations in gastroenterology, a well trained workforce and strategic planning are required to optimise health-care utilisation. The analysis calls attention to the following in the future of gastroenterology: artificial intelligence and the use of big data will speed up discovery and smarter health-care provision in the field; the growth and diversification of gastroenterological specialties will improve specialised care for patients, but could promote fragmentation of care and health system inefficiencies; and furthermore, thoughtful planning is needed to reach an effective balance between the need for subspecialists and the value of general gastroenterology services.

Cumulative sum learning curves guiding multicenter multidisciplinary quality improvement of EUS-guided tissue acquisition of solid pancreatic lesions

Background and study aims  In this study, we evaluated the performance of community hospitals involved in the Dutch quality in endosonography team regarding yield of endoscopic ultrasound (EUS)-guided tissue acquisition (TA) of solid pancreatic lesions using cumulative sum (CUSUM) learning curves. The aims were to assess trends in quality over time and explore potential benefits of CUSUM as a feedback-tool. Patients and methods  All consecutive EUS-guided TA procedures for solid pancreatic lesions were registered in five community hospitals between 2015 and  2018. CUSUM learning curves were plotted for overall performance and for performance per center. The American Society of Gastrointestinal Endoscopy-defined key performance indicators, rate of adequate sample (RAS), and diagnostic yield of malignancy (DYM) were used for this purpose. Feedback regarding performance was provided on multiple occasions at regional interest group meetings during the study period. Results  A total of 431 EUS-guided TA procedures in 403 patients were included in this study. The overall and per center CUSUM curves for RAS improved over time. CUSUM curves for DYM revealed gradual improvement, reaching the predefined performance target (70 %) overall, and in three of five contributing centers in 2018. Analysis of a sudden downslope development in the CUSUM curve of DYM in one center revealed temporary absence of a senior cytopathologist to have had a temporary negative impact on performance. Conclusions  CUSUM-derived learning curves allow for assessment of best practices by comparison among peers in a multidisciplinary multicenter quality improvement initiative and proved to be a valuable and easy-to-interpret means to evaluate EUS performance over time.

Standardization of EUS imaging and reporting in high-risk individuals of pancreatic adenocarcinoma: consensus statement of the Pancreatic Cancer Early Detection Consortium

BACKGROUND AND AIMS

Pancreatic ductal adenocarcinoma is an aggressive disease most often diagnosed after local progression or metastatic dissemination, precluding resection and resulting in a high mortality rate. For individuals with elevated personal risk of the development of pancreatic cancer, EUS is a frequently used advanced imaging and diagnostic modality. However, variability in the expertise and definition of EUS findings exists among gastroenterologists, as well as a lack of standardized reporting of relevant findings at the time of examination. Adoption of standardized EUS reporting, using a universally accepted and agreed on terminology, is needed.

METHODS

A consensus statement designed to create a standardized reporting template was authored by a multidisciplinary group of experts in pancreatic diseases that includes gastroenterologists, radiologists, surgeons, oncologists, and geneticists. This statement was developed using a modified Delphi process as part of the Pancreatic Cancer Early Detection Consortium, and >75% agreement was required to reach consensus.

RESULTS

We identified reporting elements and present standardized reporting templates for EUS indications, procedural data, EUS image capture, and descriptors of findings, tissue sampling, and postprocedural assessment of adequacy.

CONCLUSIONS

Adoption of this standardized EUS reporting template should improve consistency in clinical decision-making for individuals with elevated risk of pancreatic cancer by providing complete and accurate reporting of pancreatic abnormalities. Standardization will also help to facilitate research and clinical trial design by using clearly defined and consistent imaging descriptions, thus allowing for comparison of results across different centers.

UK Joint Advisory Group consensus statements for training and certification in endoscopic retrograde cholangiopancreatography

Background and study aims  Despite the high-risk nature of endoscopic retrograde cholangiopancreatography (ERCP), a robust and standardized credentialing process to ensure competency before independent practice is lacking worldwide. On behalf of the Joint Advisory Group (JAG), we aimed to develop evidence-based recommendations to form the framework of ERCP training and certification in the UK. Methods  Under the oversight of the JAG, a modified Delphi process was conducted with stakeholder representation from the British Society of Gastroenterology, Association of Upper Gastrointestinal Surgeons, trainees and trainers. Recommendations on ERCP training and certification were formulated after formal literature review and appraised using the GRADE tool. These were subjected to electronic voting to achieve consensus. Accepted statements were peer-reviewed by JAG and relevant Specialist Advisory Committees before incorporation into the ERCP certification pathway. Results  In total, 27 recommendation statements were generated for the following domains: definition of competence (9 statements), acquisition of competence (8 statements), assessment of competence (6 statements) and post-certification support (4 statements). The consensus process led to the following criteria for ERCP certification: 1) performing ≥ 300 hands-on procedures; 2) attending a JAG-accredited ERCP skills course; 3) in modified Schutz 1-2 procedures: achieving native papilla cannulation rate ≥80%, complete bile duct clearance ≥ 70 %, successful stenting of distal biliary strictures ≥ 75 %, physically unassisted in ≥ 80 % of cases; 4) 30-day post-ERCP pancreatitis rates ≤5 %; and 5) satisfactory performance in formative and summative direct observation of procedural skills (DOPS) assessments. Conclusions  JAG certification in ERCP has been developed following evidence-based consensus to quality assure training and to ultimately improve future standards of ERCP practice.

Pilot prospective study on formal training in per-oral endoscopic myotomy (POEM) during advanced endoscopy fellowship

Background and study aims  Gastroenterology societies have recently proposed core curricula for training in per-oral endoscopic myotomy (POEM) based on expert opinion with limited data on its applicability for advanced endoscopy fellowship (AEF) trainees. We prospectively evaluated the feasibility of a structured POEM training curriculum during a dedicated AEF and the trainee's performance during independent practice. Methods  This was a single-center prospective study evaluating a trainee's performance of POEM using a structured assessment tool (POEMAT) to assess core cognitive and technical skills. The trainee's performance was then prospectively assessed during the first 12 months of independent practice. Results  The trainee, who had not prior background in submucosal endoscopy, first observed 22 POEM cases followed by 35 hands-on procedures during his advanced endoscopy fellowship. Based on the POEMAT, submucosal entry and mucosal incision closure were the most challenging technical aspects, while cognitive skills were uniformly attained early in training. Overall, the trainee was able to cross the threshold for competence in his POEMAT performance score in 15 of his last 18 cases (83.3 %). The trainee performed 16 POEMs (baseline mean Eckardt 7.2) in his first 12 months of independent practice. Mean procedural time was 79.8 minutes (interquartile range: 67-94 minutes minutes) with no adverse events. Clinical success (Eckardt score < 3) was achieved in 100 % of the cases at a median follow-up of 20 weeks. Conclusions  Results from this pilot study support the adoptability of the recently proposed core curricula for POEM training within the context of a dedicated AEF and provide a potential blueprint for future studies of performance in POEM among trainees.

Curriculum for ERCP and endoscopic ultrasound training in Europe: European Society of Gastrointestinal Endoscopy (ESGE) Position Statement

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.

Important Quality Metrics and Standardization in Endoscopy

Quality metrics and standardization has become critical as the Affordable Care Act mandates that the Center for Medicare and Medicaid Services change reimbursement from volume to a value-based system. While the most commonly used quality indicators are related to that of colonoscopy, quality metrics for other procedures and endoscopy units have been developed mainly by the American College of Gastroenterology and the American Society of Gastrointestinal Endoscopy. Data to show that these quality metrics, especially in the field of advanced endoscopy as well as in the era of COVID-19 pandemic, can improve patient outcomes, are anticipated.

A prospective study on quality in endoscopic retrograde cholangiopancreatography (ERCP): trend in Italy from the REQUEST study

Background and study aims  Endoscopic retrograde cholangiopancreatography (ERCP) is a complex procedure with a relatively high rate of adverse events. Data on training of operators and fulfillment of quality indicators in Italy are scarce. The goal of this study was to assess the overall quality of ERCP in Italy compared to international standards. Patients and methods  This was a prospective, observational study from different Italian centers performing ERCP. Operators answered a questionnaire, then recorded data on ERCPs over a 1-to 3-month period. Results  Nineteen Italian centers participated in the study. The most common concern of operators about training was the lack of structured programs. Seven/19 centers routinely used conscious sedation for ERCP. Forty-one experienced operators and 21 trainees performed 766 ERCPs: a successful deep biliary cannulation in native-papilla patients was achieved in 95.1 % of cases; the post-ERCP pancreatitis (PEP) rate was 5.4 % in native-papilla patients; cholangitis rate was 1.0 %; bleeding and perforation occurred in 2.7 % and 0.4 % of the patients, respectively. Conclusions  This study revealed that, overall, ERCP is performed in the participating Italian centers meeting good quality standards, but structured training and sedation practice are still subpar. The bleeding and perforation rate slightly exceeded the American Society of Gastrointestinal Endoscopy indicator targets but they are comparable to the reported rates from other international surveys.

Adverse events associated with endoscopic retrograde cholangiopancreatography: protocol for a systematic review and meta-analysis

INTRODUCTION

Endoscopic retrograde cholangiopancreatography (ERCP) is performed to diagnose and manage conditions of the biliary and pancreatic ducts. Though effective, it is associated with common adverse events (AEs). The purpose of this study is to systematically review ERCP AE rates and report up-to-date pooled estimates.

METHODS AND ANALYSIS

A comprehensive electronic search will be conducted of relevant medical databases through 10 November 2020. A study team of eight data abstracters will independently determine study eligibility, assess quality and abstract data in parallel, with any two concordant entries constituting agreement and with discrepancies resolved by consensus. The primary outcome will be the pooled incidence of post-ERCP pancreatitis, with secondary outcomes including post-ERCP bleeding, cholangitis, perforation, cholecystitis, death and unplanned healthcare encounters. Secondary outcomes will also include rates of specific and overall AEs within clinically relevant subgroups determined a priori. DerSimonian and Laird random effects models will be used to perform meta-analyses of these outcomes. Sources of heterogeneity will be explored via meta-regression. Subgroup analyses based on median dates of data collection across studies will be performed to determine whether AE rates have changed over time.

ETHICS AND DISSEMINATION

Ethics approval is not required for this study as it is a planned meta-analysis of previously published data. Participant consent is similarly not required. Dissemination is planned via presentation at relevant conferences in addition to publication in peer-reviewed journals.PROSPERO registration numberCRD42020220221.

GAPS-EUS: a new and reliable tool for the assessment of basic skills and performance in EUS among endosonography trainees

Objective

Endosonography (EUS) is a useful but complex diagnostic modality which requires advanced endoscopy training and guidance by a supervisor. Since learning curves vary among individuals, assessment of the actual competence among EUS trainees is important.

Design/methods

We designed a novel assessment tool entitled Global Assessment of Performance and Skills in EUS (GAPS-EUS) for assessing skills among EUS trainees. Five quality indicators were marked on a five-grade scale by the supervisor (Observer Score) and by the trainee (Trainee Score). Trainees were included in two high-volume centres (Gothenburg, Sweden, and Bologna, Italy). Outcomes were feasibility, patient safety, reliability, and validity of GAPS-EUS in trainee-performed EUS procedures.

Results

Twenty-two EUS-trainees were assessed in a total of 157 EUS procedures with a completion rate of 157/157 (100 %) and a patient adverse event rate of 2/157 (1.3 %; gastroenteritis n=1, fever n=1). GAPS-EUS showed a high measurement reliability (Cronbach’s alpha coefficient=0.87) and a high inter-rater reliability comparing the supervisor and the trainee (r=0.83, r²=0.69, p<0.001). The construct of GAPS-EUS was verified by comparing low-level and high-level performance procedures and the content validity by recording that the EUS-FNA manoeuvre resulted in a lower score than other aspects of EUS 3.07 (95% CI 2.91 to 3.23) vs 3.51 (95% CI 3.37 to 3.65) (p<0.001). External validity was confirmed via similar findings in both centres.

Conclusion

GAPS-EUS is an easy-to-use and reliable tool with a recorded high validity for the assessment of competence among trainees in EUS. It can be recommended to centres involved in the education of future endosonographers.

Advanced endoscopy fellowship training in the United States: recent trends in American Society for Gastrointestinal Endoscopy advanced endoscopy fellowship match, trainee experience, and postfellowship employment

BACKGROUND AND AIMS

The American Society for Gastrointestinal Endoscopy (ASGE) advanced endoscopy fellowship (AEF) match offers a structured application process for AEF training in the United States. Our aim was to describe recent trends in AEF match, trainee experience, and postfellowship employment.

METHODS

ASGE AEF match data from 2012 to 2020 were reviewed. Online surveys were sent to advanced endoscopy trainees in 2019 and 2020 to explore their perceptions about AEF training and postfellowship jobs.

RESULTS

Data for 2020 showed 19% of matched applicants were women, 55% foreign medical graduates, and 17.5% U.S. visa holders. The number of AEF match applicants increased by 15.6% (90 in 2012 to 104 in 2020) and number of AEF programs increased by 23.5% (51 in 2012 to 63 in 2020). The average applicant match rate was 57% (range, 52.8%-60.6%) and position match rate 87.9% (range, 79.1%-94.6%). Ninety-one percent of trainees (n = 58) rated the quality of their training as very good/excellent; 75% of trainees participated in >300 ERCPs and 64.1% in >300 EUS cases. Seventy percent of trainees reported that advanced endoscopic procedures comprised ≤50% of their procedure volume in their first job, and 71.9% believed it was not easy to find a job after fellowship; however, 97% believed they would make the same decision to pursue AEF training again.

CONCLUSIONS

There has been a steady increase in the number of advanced endoscopy applicants and training positions over recent years. Most graduating fellows reported 50% or less of their upcoming clinical practice would involve advanced endoscopic procedures. Future studies are needed to further clarify employment opportunities and personnel needs for advanced endoscopists.

Artificial intelligence in gastrointestinal radiology: A review with special focus on recent development of magnetic resonance and computed tomography

Artificial intelligence (AI), particularly the deep learning technology, have been proven influential to radiology in the recent decade. Its ability in image classification, segmentation, detection and reconstruction tasks have substantially assisted diagnostic radiology, and has even been viewed as having the potential to perform better than radiologists in some tasks. Gastrointestinal radiology, an important subspecialty dealing with complex anatomy and various modalities including endoscopy, have especially attracted the attention of AI researchers and engineers worldwide. Consequently, recently many tools have been developed for lesion detection and image construction in gastrointestinal radiology, particularly in the fields for which public databases are available, such as diagnostic abdominal magnetic resonance imaging (MRI) and computed tomography (CT). This review will provide a framework for understanding recent advancements of AI in gastrointestinal radiology, with a special focus on hepatic and pancreatobiliary diagnostic radiology with MRI and CT. For fields where AI is less developed, this review will also explain the difficulty in AI model training and possible strategies to overcome the technical issues. The authors’ insights of possible future development will be addressed in the last section.

Development and initial validation of an instrument for video-based assessment of technical skill in ERCP

BACKGROUND AND AIMS

The accurate measurement of technical skill in ERCP is essential for endoscopic training, quality assurance, and coaching of this procedure. Hypothesizing that technical skill can be measured by analysis of ERCP videos, we aimed to develop and validate a video-based ERCP skill assessment tool.

METHODS

Based on review of procedural videos, the task of ERCP was deconstructed into its basic components by an expert panel that developed an initial version of the Bethesda ERCP Skill Assessment Tool (BESAT). Subsequently, 2 modified Delphi panels and 3 validation exercises were conducted with the goal of iteratively refining the tool. Fully crossed generalizability studies investigated the contributions of assessors, ERCP performance, and technical elements to reliability.

RESULTS

Twenty-nine technical elements were initially generated from task deconstruction. Ultimately, after iterative refinement, the tool comprised 6 technical elements and 11 subelements. The developmental process achieved consistent improvements in the performance characteristics of the tool with every iteration. For the most recent version of the tool, BESAT-v4, the generalizability coefficient (a reliability index) was .67. Most variance in BESAT scores (43.55%) was attributed to differences in endoscopists' skill, indicating that the tool can reliably differentiate between endoscopists based on video analysis.

CONCLUSIONS

Video-based assessment of ERCP skill appears to be feasible with a novel instrument that demonstrates favorable validity evidence. Future steps include determining whether the tool can discriminate between endoscopists of varying experience levels and predict important outcomes in clinical practice.

Training in advanced bilio-pancreatic endoscopy

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.

Evaluating learning curves and competence in colorectal EMR among advanced endoscopy fellows: a pilot multicenter prospective trial using cumulative sum analysis

BACKGROUND AND AIMS

Data on colorectal EMR (C-EMR) training are lacking. We aimed to evaluate C-EMR training among advanced endoscopy fellows (AEFs) by using a standardized assessment tool (STAT).

METHODS

This multicenter prospective study used a STAT to grade AEF training in C-EMR during their 12-month fellowship. Cumulative sum analysis was used to establish learning curves and competence for cognitive and technical components of C-EMR and overall performance. Sensitivity analysis was performed by varying failure rates. AEFs completed a self-assessment questionnaire to assess their comfort level with performing C-EMR at the completion of their fellowship.

RESULTS

Six AEFs (189 C-EMRs; mean per AEF, 31.5 ± 18.5) were included. Mean polyp size was 24.3 ± 12.6 mm, and mean procedure time was 22.6 ± 16.1 minutes. Learning curve analyses revealed that less than 50% of AEFs achieved competence for key cognitive and technical C-EMR endpoints. All 6 AEFs reported feeling comfortable performing C-EMR independently at the end of their training, although only 2 of them achieved competence in their overall performance. The minimum threshold to achieve competence in these 2 AEFs was 25 C-EMRs.

CONCLUSIONS

A relatively low proportion of AEFs achieved competence on key cognitive and technical aspects of C-EMR during their 12-month fellowship. The relatively low number of C-EMRs performed by AEFs may be insufficient to achieve competence, in spite of their self-reported readiness for independent practice. These pilot data serve as an initial framework for competence threshold, and suggest the need for validated tools for formal C-EMR training assessment.

Adverse Events Associated With Therapeutic Endoscopic Retrograde Pancreatography

OBJECTIVES

Data regarding the safety of endoscopic retrograde pancreatography (ERP) are limited compared with biliary endoscopic retrograde cholangiopancreatography. The aim of this study was to determine adverse events (AEs) associated with therapeutic ERP.

METHODS

This single-center retrospective study examined consecutive therapeutic ERPs with the primary intention of cannulating the pancreatic duct. Multivariate logistic regression was performed to identify risk factors for AEs.

RESULTS

A total of 3023 ERPs were performed in 1288 patients (mean age, 50.3 years; 57.8% female) from January 2000 to January 2017. Overall AE rate was 18.9% with abdominal pain requiring admission (9.8%) and post-ERP pancreatitis (5.7%) being most common. On multivariate analysis, female sex (adjusted odds ratio [aOR], 2.3; 95% confidence interval [CI], 1.9-2.9), acute recurrent pancreatitis (aOR, 5.0; 95% CI, 1.7-15.3), chronic pancreatitis (aOR, 1.8; 95% CI, 1.3-2.6), and pancreatic sphincter of Oddi dysfunction (aOR, 2.1; 95% CI, 1.4-3.3) were associated with an increased risk of overall AEs. Pancreatic sphincterotomy (aOR, 1.9; 95% CI, 1.5-2.4) and therapeutic stenting (aOR, 1.6; 95% CI, 1.2-2.2) also increased the risk of AEs.

CONCLUSIONS

Nearly 1 in 5 patients who undergo therapeutic ERP will experience an AE; however, the rates of major AEs, including post-ERP pancreatitis, bleeding, and perforation, are low.

Development of an automated ERCP Quality Report Card using structured data fields

Background and aims

Measuring adherence to ERCP quality indicators (QIs) is confounded by variability in indications, maneuvers, and documentation styles. We hypothesized that incorporation of mandatory, structured data fields within reporting software would permit accurate measurement of QI adherence rates and facilitate generation of a provider ERCP report card.

Methods

At two referral centers, endoscopy documentation software was modified to generate provider alerts prior to finalizing the note. The alerts reminded the provider to document the following components in a standardized manner: indication, altered anatomy, prior interventions, and QIs deemed high priority by society consensus, study authors, or both. Adherence rates for each QI were calculated in aggregate and by provider via data extraction directly from the procedure documentation software. Medical records were reviewed manually to measure the accuracy of automated data extraction. Accuracy of automated measurement for each QI was calculated against results derived by manual review.

Results

During the 9-month study period, 1,376 ERCP procedures were completed by 8 providers. Manual medical record review confirmed high (98-100%) accuracy of automatic extraction of ERCP QIs from the endoscopy report, including cannulation rate of the native papilla and complete extraction of common bile duct stones. An ERCP report card was generated, allowing for individual comparison of adherence to ERCP QIs with colleagues at their institution and others.

Conclusion

In this pilot study, use of mandatory, structured data fields within clinical ERCP reports permit the accurate measurement of high priority ERCP QIs and the subsequent generation of interval report cards.

Attitudes to radiation safety and cholangiogram interpretation in endoscopic retrograde cholangiopancreatography (ERCP): a UK survey

BACKGROUND

Fluoroscopy during endoscopic retrograde cholangiopancreatography (ERCP) exposes staff and patients to potentially harmful ionizing radiation. We performed a UK survey to explore trainee and trainer attitudes to radiation protection and cholangiogram interpretation in ERCP.

METHODS

An electronic 10-point survey was prospectively distributed to endoscopy unit leads, training programme directors between October and November 2019. Only UK-based ERCP trainees and trainers with hands-on procedural exposure were eligible for the survey.

RESULTS

The survey was completed by 107 respondents (58 trainees and 49 trainers), with an estimated overall response rate of 46%. Overall, 49% of respondents were up to date with their radiation protection course, 38% were aware of European Basic safety standards directive (BSSD), 38% wore radiation protection goggles, and 40% were aware of the average radiation screening dose per ERCP procedure. Compared with trainers, trainees were less likely to routinely wear thyroid protection shields (76% vs 92%; p=0.028), have awareness of the BSSD (20% vs 49%; p=0.037) or know their average procedural radiation dosages (21% vs 63%; p<0.001). With regard to cholangiogram interpretation, only 26% had received formal training, with 97% of trainees expressing a desire for further training.

CONCLUSION

This survey highlights a relative complacency in safety attitudes to radiation protection during ERCP. These data provide impetus to improve training and quality assurance in radiation protection, which should be regarded as a mandatory safety aspect prior to commencing hands-on ERCP training.

Time Given to Trainees to Attempt Cannulation During Endoscopic Retrograde Cholangiopancreatography Varies by Training Program and Is Not Associated With Competence

Advanced endoscopy training programs (AETPs) were developed as a result of the lack of comprehensive endoscopic retrograde cholangiopancreatography (ERCP) training during gastroenterology fellowships. There is no standardized curriculum for AETPs and the influence of program- and trainer-associated factors on trainee competence in ERCP has not been investigated adequately. In prior work, we showed that advanced endoscopy trainees (AETs) achieve ERCP competence at varying rates.^1,2 The aims of this study were to measure the variability in time given to AETs to attempt cannulation between AETPs and throughout the 1-year training period, and to determine the association between AET cannulation time and AET competence at the end of training.

Learning curve of double-guidewire technique by trainees during hands-on endoscopic retrograde cholangiopancreatography training

BACKGROUND AND AIMS

Double-guidewire technique (DWT) has been successfully performed by experts in difficult biliary cannulation as an advanced technique. This study aimed to define the learning curve and safety of DWT by trainees during hands-on endoscopic retrograde cholangiopancreatography (ERCP) training.

METHODS

Patients were eligible for inclusion in the study if the biliary cannulation was difficult and the pancreatic duct was inadvertently cannulated. DWT was performed by two trainees randomly under trainers' guidance. The primary outcome was the success rate of DWT biliary cannulation of trainees. Cumulative sum analysis was used to generate visual learning curves.

RESULTS

A total of 60 patients with difficult cannulation were enrolled. The main indications for ERCP were common bile duct stones (65%) and biliary stricture (31.7%). The learning curve analysis showed that to achieve a 70% rate of successful DWT, 12 procedures were needed for trainee A and 15 for trainee B. Higher targeted success rate of DWT could be achieved if the number of DWT procedures increased. Compared with the early stage of learning DWT (case 1 to 15 for each trainee), trainees had significantly higher DWT success rate in the late stage (36.7% [11/30] vs 80% [24/30], P = 0.001). The final success rate of cannulation was 98.3% (59/60). The overall rate of post-ERCP pancreatitis and adverse events was 6.7% (4/60) and 8.3% (5/60), respectively.

CONCLUSIONS

Double-guidewire technique was safely performed by two novel trainees during hands-on ERCP training. Fifteen procedures may be enough for trainees to achieve the competency of performing DWT. (Clinicaltrials.gov number: NCT03707613).

Deep learning-based pancreas segmentation and station recognition system in EUS: development and validation of a useful training tool (with video)

BACKGROUND AND AIMS

EUS is considered one of the most sensitive modalities for pancreatic cancer detection, but it is highly operator-dependent and the learning curve is steep. In this study, we constructed a system named BP MASTER (pancreaticobiliary master) for EUS training and quality control.

METHODS

The standard procedure of pancreatic EUS was divided into 6 stations. We developed a station classification model and a pancreas/abdominal aorta/portal confluence segmentation model with 19,486 images and 2207 images, respectively. Then, we used 1920 images and 700 images for classification and segmentation internal validation, respectively. To test station recognition we used 396 videos clips. An independent data set containing 180 images was applied for comparing the performance between models and EUS experts. Seven hundred sixty-eight images from 2 other hospitals were used for external validation. A crossover study was conducted to test the system effect on reducing difficulty in ultrasonographics interpretation among trainees.

RESULTS

The models achieved 94.2% accuracy in station classification and .836 dice in segmentation at internal validation. At external validation, the models achieved 82.4% accuracy in station classification and .715 dice in segmentation. For the video test, the station classification model achieved a per-frame accuracy of 86.2%. Compared with EUS experts, the models achieved 90.0% accuracy in classification and .77 and .813 dice in blood vessel and pancreas segmentation, which is comparable with that of experts. In the crossover study, trainee station recognition accuracy improved from 67.2% to 78.4% (95% confidence interval, .058-1.663; P < .01).

CONCLUSIONS

The BP MASTER system has the potential to play an important role in shortening the pancreatic EUS learning curve and improving EUS quality control in the future.

Esophageal Manometry Competency Program Improves Gastroenterology Fellow Performance in Motility Interpretation

INTRODUCTION

Competency-based medical education (CBME) for interpretation of esophageal manometry is lacking; therefore, motility experts and instructional designers developed the esophageal manometry competency (EMC) program: a personalized, adaptive learning program for interpretation of esophageal manometry. The aim of this study was to implement EMC among Gastroenterology (GI) trainees and assess the impact of EMC on competency in manometry interpretation.

METHODS

GI fellows across 14 fellowship programs were invited to complete EMC from February 2018 to October 2018. EMC includes an introductory video, baseline assessment of manometry interpretation, individualized learning pathways, and final assessment of manometry interpretation. The primary outcome was competency for interpretation in 7 individual skill sets.

RESULTS

Forty-four GI trainees completed EMC. Participants completed 30 cases, each including 7 skill sets. At baseline, 4 (9%) participants achieved competency for all 7 skills compared with 24 (55%) at final assessment (P < 0.001). Competency in individual skills increased from a median of 4 skills at baseline to 7 at final assessment (P < 0.001). The greatest increase in skill competency was for diagnosis (Baseline: 11% vs Final: 68%; P < 0.001). Accuracy improved for distinguishing between 5 diagnostic groups and was highest for the Outflow obstructive motility disorder (Baseline: 49% vs Final: 76%; P < 0.001) and Normal motor function (50% vs 80%; P < 0.001).

DISCUSSION

This prospective multicenter implementation study highlights that an adaptive web-based training platform is an effective tool to promote CBME. EMC completion was associated with significant improvement in identifying clinically relevant diagnoses, providing a model for integrating CBME into subspecialized areas of training.

GIE Editorial Board top 10 topics: advances in GI endoscopy in 2019

The American Society for Gastrointestinal Endoscopy's GIE Editorial Board reviewed original endoscopy-related articles published during 2019 in Gastrointestinal Endoscopy and 10 other leading medical and gastroenterology journals. Votes from each individual member were tallied to identify a consensus list of 10 topic areas of major advances in GI endoscopy. Individual board members summarized important findings published in these 10 areas of disinfection, artificial intelligence, bariatric endoscopy, adenoma detection, polypectomy, novel imaging, Barrett's esophagus, third space endoscopy, interventional EUS, and training. This document summarizes these "top 10" endoscopic advances of 2019.

Effect of individualized feedback on learning curves in EGD and colonoscopy: a cluster randomized controlled trial

BACKGROUND AND AIMS

Gastroenterology fellowships need to ensure that trainees achieve competence in upper endoscopy (EGD) and colonoscopy. Because the impact of structured feedback remains unknown in endoscopy training, this study compared the effect of structured feedback with standard feedback on trainee learning curves for EGD and colonoscopy.

METHODS

In this multicenter, cluster, randomized controlled trial, trainees received either individualized quarterly learning curves or feedback standard to their fellowship. Assessment was performed in all trainees using the Assessment of Competency in Endoscopy tool on 5 consecutive procedures after every 25 EGDs and colonoscopies. Individual learning curves were created using cumulative sum (CUSUM) analysis. The primary outcome was the mean CUSUM score in overall technical and overall cognitive skills.

RESULTS

In all, 13 programs including 132 trainees participated. The intervention arm (6 programs, 51 trainees) contributed 558 EGD and 600 colonoscopy assessments. The control arm (7 programs, 81 trainees) provided 305 EGD and 468 colonoscopy assessments. For EGD, the intervention arm (-.7 [standard deviation {SD}, 1.3]) had a superior mean CUSUM score in overall cognitive skills compared with the control arm (1.6 [SD, .8], P = .03) but not in overall technical skills (intervention, -.26 [SD, 1.4]; control, 1.76 [SD, .7]; P = .06). For colonoscopy, no differences were found between the 2 arms in overall cognitive skills (intervention, -.7 [SD, 1.3]; control, .7 [SD, 1.3]; P = .95) or overall technical skills (intervention, .1 [SD, 1.5]; control, -.1 [SD, 1.5]; P = .77).

CONCLUSIONS

Quarterly feedback in the form of individualized learning curves did not affect learning curves for EGD and colonoscopy in a clinically meaningful manner. (Clinical trial registration number: NCT02891304.).

Impact of balloon inflation on the insertion of endoscopic ultrasound: a prospective, randomized controlled trial

Background and study aims  During endoscopic ultrasound (EUS), patients may experience severe discomfort. The radial echoendoscope has a balloon around its tip. Balloon inflation prior to insertion may reduce contact injury and pharyngeal pain. The purpose of this study was to investigate the effect of balloon inflation on pharyngeal pain during insertion. Patients and methods  Patients who underwent radial EUS for pancreatobiliary disease were randomized into standard insertion or balloon-inflated insertion. The primary outcome was the proportion of moderate-to-severe pharyngeal pain. Secondary outcomes were the degree of pharyngeal pain, risk factors for moderate pharyngeal pain, procedure-related adverse events, and pharyngeal pain depending on the experience of the endoscopist. Results  A total of 481 patients were randomized into two groups: standard insertion (238) and balloon inflation (243). No statistically significant differences in proportion of moderate-to-severe pain were found (26.5 % vs. 20.2 %, P  = 0.107). Balloon inflation (HR 0.65; 95 % CI (0.42-0.98, P  = 0.041) was a protective factor against moderate pain. Balloon inflation reduced the proportion of patients with moderate-to-severe pain when performed by physicians with less than 3months of experience with EUS (44.7 % vs. 25.3 %, P  = 0.012). Conclusion  Balloon inflation did not reduce the absolute degree of post-procedural pain with EUS, but it reduced the number of patients with moderate-to-severe pain when performed by physicians with less than 3 months of experience.

A Prospective Multicenter Study Evaluating Endoscopy Competence Among Gastroenterology Trainees in the Era of the Next Accreditation System

PURPOSE

The Next Accreditation System requires training programs to demonstrate competence among trainees. Within gastroenterology (GI), there are limited data describing learning curves and structured assessment of competence in esophagogastroduodenoscopy (EGD) and colonoscopy. In this study, the authors aimed to demonstrate the feasibility of a centralized feedback system to assess endoscopy learning curves among GI trainees in EGD and colonoscopy.

METHOD

During academic year 2016-2017, the authors performed a prospective multicenter cohort study, inviting participants from multiple GI training programs. Trainee technical and cognitive skills were assessed using a validated competence assessment tool. An integrated, comprehensive data collection and reporting system was created to apply cumulative sum analysis to generate learning curves that were shared with program directors and trainees on a quarterly basis.

RESULTS

Out of 183 fellowships invited, 129 trainees from 12 GI fellowships participated, with an overall trainee participation rate of 72.1% (93/129); the highest participation level was among first-year trainees (90.9%; 80/88), and the lowest was among third-year trainees (51.2%; 27/53). In all, 1,385 EGDs and 1,293 colonoscopies were assessed. On aggregate learning curve analysis, third-year trainees achieved competence in overall technical and cognitive skills, while first- and second-year trainees demonstrated the need for ongoing supervision and training in the majority of technical and cognitive skills.

CONCLUSIONS

This study demonstrated the feasibility of using a centralized feedback system for the evaluation and documentation of trainee performance in EGD and colonoscopy. Furthermore, third-year trainees achieved competence in both endoscopic procedures, validating the effectiveness of current training programs.
