Canadian credentialing guidelines for endoscopic retrograde cholangiopancreatography

Papilla of Vater morphology as an influencing factor in successful cannulation during resident training in advanced endoscopy. A prospective clinical study

INTRODUCTION AND AIM

Endoscopic retrograde cholangiopancreatography (ERCP) is a complex procedure. Clinical guidelines assess competence in ERCP through a defined number of procedures, but multiple factors are involved. Our aim was to analyze the morphology of the papilla of Vater as an independent factor in selective common bile duct cannulation during resident training.

MATERIAL AND METHODS

Patients that underwent ERCP were studied consecutively. All ERCPs were begun by a resident in training. The type of papilla was classified according to Haraldsson, including those with previous sphincterotomy. Cannulation difficulty and success and their relation to the type of papilla were documented. The analysis was divided into three 4-month periods.

RESULTS

Of the 429 patients, cannulation was difficult in 101 (23.5%). The residents achieved selective cannulation of the common bile duct in 276 (64.3%) and the cannulation success rate at the end of their training was 81.7%. Cannulation was performed with the least difficulty in papillae with previous sphincterotomy (2.8%), unlike the type 4 papilla, which was difficult to cannulate in 50% of the cases. The lowest overall cannulation success was in the type 2 papilla (81.8%).

CONCLUSION

Papilla type can influence cannulation success, but it is not the only related factor. Patients that underwent previous sphincterotomy appear to be the cases in whom ERCP training can be started.

Assessing Patient Radiation Exposure in Endoscopic Retrograde Cholangiopancreatography: A Multicenter Retrospective Analysis of Procedural Complexity and Clinical Factors

BACKGROUND AND AIMS

Endoscopic retrograde cholangiopancreatography (ERCP) procedures can result in significant patient radiation exposure. This retrospective multicenter study aimed to assess the influence of procedural complexity and other clinical factors on radiation exposure in ERCP.

METHODS

Data on kerma-area product (KAP), air-kerma at the reference point (Ka,r), fluoroscopy time, and the number of exposures, and relevant patient, procedure, and operator factors were collected from 2641 ERCP procedures performed at four university hospitals. The influence of procedural complexity, assessed using the American Society for Gastrointestinal Endoscopy (ASGE) and HOUSE complexity grading scales, on radiation exposure quantities was analyzed within each center. The procedures were categorized into two groups based on ERCP indications: primary sclerosing cholangitis (PSC) and other ERCPs.

RESULTS

Both the ASGE and HOUSE complexity grading scales had a significant impact on radiation exposure quantities. Remarkably, there was up to a 50-fold difference in dose quantities observed across the participating centers. For non-PSC ERCP procedures, the median KAP ranged from 0.9 to 64.4 Gy·cm2 among the centers. The individual endoscopist also had a substantial influence on radiation dose.

CONCLUSIONS

Procedural complexity grading in ERCP significantly affects radiation exposure. Higher procedural complexity is typically associated with increased patient radiation dose. The ASGE complexity grading scale demonstrated greater sensitivity to changes in radiation exposure compared to the HOUSE grading scale. Additionally, significant variations in dose indices, fluoroscopy times, and number of exposures were observed across the participating centers.

Global trends in training and credentialing guidelines for gastrointestinal endoscopy: a systematic review

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.

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.

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.

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.

Endoscopic Management of Acute Biliopancreatic Disorders

PURPOSE

Endoscopy is playing an ever-increasing role in the management of acute biliopancreatic disorders. With the management paradigm shifting away from more invasive surgical approaches, surgeons need to be aware of the treatment options available to improve patient care. Our manuscript serves to improve surgeons' knowledge and understanding of these emerging treatment modalities to expand their algorithmic approach to biliopancreatic disorders.

METHODS

Specific acute biliopancreatic disorders were identified from the literature and personal practice to create a structured review of common problems experienced by a surgeon of the gastrointestinal tract. An exhaustive literature review was performed to identify and analyze endoscopic treatment modalities for these disorders.

RESULTS

Endoscopic therapies continue to expand rapidly with a robust supportive literature. Data on endoscopic treatment strategies for acute biliopancreatic disorders demonstrate valuable improvements in outcomes in a number of these disorders.

DISCUSSION

Acute biliopancreatic disorders represent one of the most challenging pathophysiologies that a surgeon of the gastrointestinal tract may face. This manuscript represents a review of available endoscopic instrumentation as well as the author's interpretation of the current literature regarding indications and outcomes of endoscopic management for acute biliopancreatic disorders. Although this article does not supplant formal training in therapeutic endoscopy, surgeons reading this article should understand the role endoscopy plays in the management of acute biliopancreatic disorders.

ERCP quality indicators: The experience of a high-volume tertiary care center in Saudi Arabia

BACKGROUND

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most technically demanding and high-risk procedures performed by GI endoscopists. Therefore, guidelines or position statements on various aspects of quality indicators, safety indicators and credentialing for ERCP have been developed by gastroenterology associations. In this paper, we evaluate the ERCP quality in a single, high-volume, tertiary care center in Saudi Arabia using a number of measures commonly stated by these organizations, and compare the experience of that center to the previously-published standards in this regard.

PATIENTS AND METHODS

This is a descriptive, retrospective chart review of a consecutive sample taken over 12 continuous months (July 2016-June 2017). Data collected included demographic characteristics, and technical/clinical details from three time periods: preprocedure, intraprocedure, and postprocedure. Measurement parameters were all taken from the ASGE/ACG guidelines. Data was represented by the percentage of which each indicator was achieved, and the 95% proportion confidence intervals (CIs) when needed.

RESULTS

From July 2016 to June 2017, 281 ERCP procedures were performed. An outstanding majority of them (95.7%) was done for therapeutic purposes, whereas 4.3% were diagnostic procedures. The sample included 206 patients, of whom 83 (40.3%) were males. The age of the participants ranged between 11 and 101 years (mean age ± SD; 51 ± 19). The quality of ERCP at the center in which the study was done met the performance targets stated by the ASGE/ACG for almost all indicators. Adverse events reported in our series were lower than previous studies for pancreatitis and perforation, and slightly higher in the incidence of bleeding, cholangitis, and death.

CONCLUSION

In a single, high-volume, tertiary care center in Saudi Arabia, the quality of ERCP met the performance targets stated by the ASGE/ACG for almost all indicators.

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

BACKGROUND & AIMS

It is unclear whether participation in competency-based fellowship programs for endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) results in high-quality care in independent practice. We measured quality indicator (QI) adherence during the first year of independent practice among physicians who completed endoscopic training with a systematic assessment of competence.

METHODS

We performed a prospective multicenter cohort study of invited participants from 62 training programs. In phase 1, 24 advanced endoscopy trainees (AETs), from 20 programs, were assessed using a validated competence assessment tool. We used a comprehensive data collection and reporting system to create learning curves using cumulative sum analysis that were shared with AETs and trainers quarterly. In phase 2, participating AETs entered data into a database pertaining to every EUS and ERCP examination during their first year of independent practice, anchored by key QIs.

RESULTS

By the end of training, most AETs had achieved overall technical competence (EUS 91.7%, ERCP 73.9%) and cognitive competence (EUS 91.7%, ERCP 94.1%). In phase 2 of the study, 22 AETs (91.6%) participated and completed a median of 136 EUS examinations per AET and 116 ERCP examinations per AET. Most AETs met the performance thresholds for QIs in EUS (including 94.4% diagnostic rate of adequate samples and 83.8% diagnostic yield of malignancy in pancreatic masses) and ERCP (94.9% overall cannulation rate).

CONCLUSIONS

In this prospective multicenter study, we found that although competence cannot be confirmed for all AETs at the end of training, most meet QI thresholds for EUS and ERCP at the end of their first year of independent practice. This finding affirms the effectiveness of training programs. Clinicaltrials.gov ID NCT02509416.

Quality and competence in endoscopic retrograde cholangiopancreatography - Where are we 50 years later?

Training in endoscopic retrograde cholangiopancreatography (ERCP) requires the development of technical, cognitive, and integrative skills well beyond those needed for standard endoscopic procedures. So far, there are limited data regarding what constitutes competency in ERCP, including achievement and maintenance. Recent studies have highlighted overall procedural numbers are not enough to warrant competency, although more is better. We performed a comprehensive literature search until June 2017 using predetermined search terms to identify relevant articles and summarized their results as a narrative review. Selective native papilla deep cannulation should be used as a benchmark for assessing successful cannulation. Accurate and validated ERCP performance measures are needed to develop a curriculum that allows transition from numbers-based competency. However, available guidelines fail to state what degree of hands-on involvement is required by the trainee for the case to be counted in their overall procedural numbers. Qualitative assessment of competency should be done by trained raters using specially designed assessment tools. Competence continues to increase with practice following formal training in a fairly steady manner. The learning curve for overall common bile duct cannulation success may be a readily available surrogate for individual trainee progression and may correspond to learning curves for therapeutic interventions.

Surgeon-performed endoscopic retrograde cholangiopancreatography. Outcomes of 2392 procedures at two tertiary care centers

BACKGROUND

Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure that, in the United States, is traditionally performed by gastroenterologists. We hypothesized that when performed by well-trained surgeons, ERCP can be performed safely and effectively. The objectives of the study were to assess the rate of successful cannulation of the duct of interest and to assess the 30-day complication and mortality rates.

METHODS

We retrospectively reviewed the charts of 1858 patients who underwent 2392 ERCP procedures performed by five surgeons between August 2003 and June 2016 in two centers. Demographic and historical data, indications, procedure-related data and 30-day complication and mortality data were collected and analyzed.

RESULTS

The mean age was 53.4 (range 7-102) years and 1046 (56.3%) were female. 1430 (59.8%) of ERCP procedures involved a surgical endoscopy fellow. The most common indication was suspected or established uncomplicated common bile duct stones (n = 1470, 61.5%), followed by management of an existing biliary or pancreatic stent (n = 370, 15.5%) and acute biliary pancreatitis (n = 173, 7.2%). A therapeutic intervention was performed in 1564 (65.4%), a standard sphincterotomy in 1244 (52.0%), stent placement in 705 (29.5%) and stone removal in 638 (26.7%). When cannulation was attempted, the rate of successful cannulation was 94.1%. When cannulation was attempted during the patient's first ERCP the cannulation rate was 92.4%. 94 complications occurred (5.4%); the most common complication was post-ERCP pancreatitis in 75 (4.2%), significant gastrointestinal bleeding in 7 (0.4%), ascending cholangitis in 11 (0.6%) and perforation in 1 (0.05%). 11 mortalities occurred (0.5%) but none of which were ERCP-related.

CONCLUSION

When performed by well-trained surgical endoscopists, ERCP is associated with high success rate and acceptable complication rates consistent with previously published reports and in line with societal guidelines.

A Prospective Multicenter Study Evaluating Learning Curves and Competence in Endoscopic Ultrasound and Endoscopic Retrograde Cholangiopancreatography Among Advanced Endoscopy Trainees: The Rapid Assessment of Trainee Endoscopy Skills Study

BACKGROUND & AIMS

On the basis of the Next Accreditation System, trainee assessment should occur on a continuous basis with individualized feedback. We aimed to validate endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) learning curves among advanced endoscopy trainees (AETs) by using a large national sample of training programs and to develop a centralized database that allows assessment of performance in relation to peers.

METHODS

ASGE recognized training programs were invited to participate, and AETs were graded on ERCP and EUS exams by using a validated competency assessment tool that assesses technical and cognitive competence in a continuous fashion. Grading for each skill was done by using a 4-point scoring system, and a comprehensive data collection and reporting system was built to create learning curves by using cumulative sum analysis. Individual results and benchmarking to peers were shared with AETs and trainers quarterly.

RESULTS

Of the 62 programs invited, 20 programs and 22 AETs participated in this study. At the end of training, median number of EUS and ERCP performed/AET was 300 (range, 155-650) and 350 (125-500), respectively. Overall, 3786 exams were graded (EUS, 1137; ERCP-biliary, 2280; ERCP-pancreatic, 369). Learning curves for individual end points and overall technical/cognitive aspects in EUS and ERCP demonstrated substantial variability and were successfully shared with all programs. The majority of trainees achieved overall technical (EUS, 82%; ERCP, 60%) and cognitive (EUS, 76%; ERCP, 100%) competence at conclusion of training.

CONCLUSIONS

These results demonstrate the feasibility of establishing a centralized database to report individualized learning curves and confirm the substantial variability in time to achieve competence among AETs in EUS and ERCP. ClinicalTrials.gov: NCT02509416.

Education and Training Guidelines for the Board of the Korean Society of Gastrointestinal Endoscopy

The Korean Society of Gastrointestinal Endoscopy (KSGE) developed a gastrointestinal (GI) endoscopy board in 1995 and related regulations. Although the KSGE has acquired many specialists since then, the education and training aims and guidelines were insufficient. During GI fellowship training, obtaining sufficient exposure to some types of endoscopic procedures is difficult. Fellows should acquire endoscopic skills through supervised endoscopic procedures during GI fellowship training. Thus, the KSGE requires training guidelines for fellowships that allow fellows to perform independent endoscopic procedures without supervision. This document is intended to provide principles that the Committee of Education and Training of the KSGE can use to develop practical guidelines for granting privileges to perform accurate GI endoscopy safely. The KSGE will improve the quality of GI endoscopy by providing guidelines for fellowships and supervisors.

Endoscopic versus laparoscopic treatment for choledocholithiasis: a prospective randomized controlled trial

Background and study aims: Overall, 5 % to 15 % of patients undergoing cholecystectomy for cholelithiasis have concomitant bile duct stones, and the incidence of choledocholithiasis increases with age. There is no clear consensus on the best therapeutic approach (endoscopic versus surgical). Patients and methods: A prospective randomized controlled clinical trial was performed to compare three treatment options for patients with choledocholithiasis at the National Center for Minimally Invasive Surgery in Havana, Cuba from November 2007 to November 2011. The patients were randomized in three groups. Group I: patients who underwent intraoperative cholangiography (IOC) to confirm the choledocholithiasis followed by laparoscopic cholecystectomy (LC) associated with intraoperative endoscopic retrograde cholangiopancreatography (ERCP), group II: patients who underwent preoperative ERCP followed by LC during the same hospital admission and group III: patients who underwent IOC to confirm the choledocholithiasis followed by LC associated with laparoscopic common bile duct exploration (LCBDE). Results: A total of 300 patients with suspected choledocholithiasis were included in the trial and were randomized. As a result, a total of 134 patients were diagnosed with the presence of choledocholithiasis and treated during the study period. There were no significant differences in success rates of ductal stone clearance, but retained stone, postoperative complications and length of hospital stay were better in group I. Conclusions: Intraoperative ERCP/ES shows a higher rate of common bile duct stones clearance, a shorter hospital stay, and lower morbidity, but further research with a larger study population is necessary to determine the additional benefits of this procedure. The results to date suggests that in appropriate patients, single-stage treatments are the best options.

Current status of core and advanced adult gastrointestinal endoscopy training in Canada: Survey of existing accredited programs

OBJECTIVE

To determine the current status of core and advanced adult gastroenterology training in Canada.

METHODS

A survey consisting of 20 questions pertaining to core and advanced endoscopy training was circulated to 14 accredited adult gastroenterology residency program directors. For continuous variables, median and range were analyzed; for categorical variables, percentage and associated 95% CIs were analyzed.

RESULTS

All 14 programs responded to the survey. The median number of core trainees was six (range four to 16). The median (range) procedural volumes for gastroscopy, colonoscopy, percutaneous endoscopic gastrostomy and sigmoidoscopy, respectively, were 400 (150 to 1000), 325 (200 to 1500), 15 (zero to 250) and 60 (25 to 300). Eleven of 13 (84.6%) programs used endoscopy simulators in their curriculum. Eight of 14 programs (57%) provided a structured advanced endoscopy training fellowship. The majority (88%) offered training of combined endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasonography. The median number of positions offered yearly for advanced endoscopy fellowship was one (range one to three). The median (range) procedural volumes for ERCP, endoscopic ultrasonography and endoscopic mucosal resection, respectively, were 325 (200 to 750), 250 (80 to 400) and 20 (10 to 63). None of the current programs offered training in endoscopic submucosal dissection or natural orifice transluminal endoscopic surgery.

CONCLUSION

Most accredited adult Canadian gastroenterology programs met the minimal procedural requirements recommended by the Canadian Association of Gastroenterology during core training. However, a more heterogeneous experience has been observed for advanced training. Additional studies would be required to validate and standardize evaluation tools used during gastroenterology curricula.

Patterns and predictive factors of complications after endoscopic retrograde cholangiopancreatography

BACKGROUND

With an increased use of magnetic resonance imaging, the indications for endoscopic retrograde cholangiopancreatography (ERCP) have changed. Consequently, the patterns and factors predictive of complications after ERCP performed during current routine clinical practice are not well known.

METHODS

A prospective multicentre cohort study was undertaken in 11 Norwegian hospitals. Complications and mortality within 30 days after ERCP were analysed by univariable and multivariable regression analysis.

RESULTS

There were 2808 ERCP procedures, of which 2573 (91·6 per cent) were therapeutic. More than half of the patients were aged 70 years or more. Common bile duct cannulation was achieved in 2557 procedures (91·1 per cent). Complications occurred in 327 (11·6 per cent) of the procedures, including cholangitis in 100 (3·6 per cent), pancreatitis in 88 (3·1 per cent), bleeding in 66 (2·4 per cent), perforation in 25 (0·9 per cent) and cardiovascular-respiratory events in 32 (1·1 per cent). In the multivariable regression analysis, older age, increasing American Society of Anesthesiologists fitness score, centre ERCP volumes of more than 150 procedures annually and precut sphincterotomy were predictive factors for severe complications. The overall 30-day mortality rate was 2·2 per cent (63 patients), with a procedure-related mortality rate of 1·4 per cent (39 patients). Malignancy was diagnosed in 46 (73 per cent) of the patients who died.

CONCLUSION

ERCP is a procedure with considerable risk for complications. Morbidity and mortality are related to patient age and co-morbidity, as well as hospital volume of ERCP procedures and the type of intervention.

Canadian Association of Gastroenterology consensus guidelines on safety and quality indicators in endoscopy

BACKGROUND

Increasing use of gastrointestinal endoscopy, particularly for colorectal cancer screening, and increasing emphasis on health care quality, highlight the need for clearly defined, evidence-based processes to support quality improvement in endoscopy.

OBJECTIVE

To identify processes and indicators of quality and safety relevant to high-quality endoscopy service delivery.

METHODS

A multidisciplinary group of 35 voting participants developed recommendation statements and performance indicators. Systematic literature searches generated 50 initial statements that were revised iteratively following a modified Delphi approach using a web-based evaluation and voting tool. Statement development and evidence evaluation followed the AGREE (Appraisal of Guidelines, REsearch and Evaluation) and GRADE (Grading of Recommendations, Assessment, Development and Evaluation) guidelines. At the consensus conference, participants voted anonymously on all statements using a 6-point scale. Subsequent web-based voting evaluated recommendations for specific, individual quality indicators, safety indicators and mandatory endoscopy reporting fields. Consensus was defined a priori as agreement by 80% of participants.

RESULTS

Consensus was reached on 23 recommendation statements addressing the following: ethics (statement 1: agreement 100%), facility standards and policies (statements 2 to 9: 90% to 100%), quality assurance (statements 10 to 13: 94% to 100%), training, education, competency and privileges (statements 14 to 19: 97% to 100%), endoscopy reporting standards (statements 20 and 21: 97% to 100%) and patient perceptions (statements 22 and 23: 100%). Additionally, 18 quality indicators (agreement 83% to 100%), 20 safety indicators (agreement 77% to 100%) and 23 recommended endoscopy-reporting elements (agreement 91% to 100%) were identified.

DISCUSSION

The consensus process identified a clear need for high-quality clinical and outcomes research to support quality improvement in the delivery of endoscopy services.

CONCLUSIONS

The guidelines support quality improvement in endoscopy by providing explicit recommendations on systematic monitoring, assessment and modification of endoscopy service delivery to yield benefits for all patients affected by the practice of gastrointestinal endoscopy.

Contemporary use of endoscopic retrograde cholangiopancreatography (ERCP): a Norwegian prospective, multicenter study

OBJECTIVE

Novel imaging modalities have supplanted endoscopic retrograde cholangiopancreatography (ERCP) for the diagnosis of hepatobiliary pancreatic diseases, but the use of ERCP as a diagnostic and therapeutic tool in current clinical practice is not well known. The main objective of this study was to describe and evaluate contemporary use of ERCP in Norway.

MATERIAL AND METHODS

Prospective and consecutive data were collected between January 2007 and December 2009 from voluntary institutional reports of ERCP activity at participating hospitals in the Gastronet database.

RESULTS

A total of 3840 procedures at 14 hospitals were registered during the study period. Data from 3809 procedures (53% females) were available for evaluation. Patients were ≥60 years of age in 2567 (67%) procedures. High co-morbidity (ASA score ≥3) was present in 32% of patients. The main indication for ERCP was evaluation and therapy of bile duct-related disorders. Successful bile duct cannulation was achieved in 93%. Pre-cut sphincterotomy was performed in 5% of procedures, and a guide wire to facilitate duct access was employed in 63%. Sphincterotomy, treatment for common bile duct stones (CBDS), and an insertion or change of bile duct stents were the most commonly employed procedures. Complications occurred in 10% of the patients, with a procedure-related mortality of 1%.

CONCLUSIONS

In Norway, ERCP is predominantly performed for CBDS and biliary strictures in elderly patients with associated co-morbidity. Patient selection, indications, and procedures are in concert with international guidelines and recommendations. Disease patterns in Norway differ slightly from those observed in central Europe and North America.
