Motion training on a validated mechanical ERCP simulator improves novice endoscopist performance of selective cannulation: a multicenter trial.

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

Project description:Background/aimsRecently the European Society of Gastrointestinal Endoscopy delivered guidelines on the prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) and on the papillary cannulation and sphincterotomy techniques at endoscopic retrograde cholangiopancreatography (ERCP). There are no data concerning current practices in Portugal. The aim of this study was to capture practice patterns of Portuguese pancreaticobiliary endoscopists with special interest in the prevention of PEP and cannulation techniques.MethodsA written survey was distributed to all pancreaticobiliary endoscopists attending the first Portuguese meeting dedicated to ERCP in November 2016. The main outcome measures were: technique used for standard biliary cannulation, use of nonsteroidal anti-inflammatory drugs (NSAIDs) in PEP, attempting prophylactic pancreatic stenting after using pancreatic guidewire (PGW)-assisted biliary cannulation in patients where biliary cannulation was difficult, and use of precut as the first rescue technique when biliary cannulation was difficult.ResultsCompleted surveys were collected from 28 of the 32 pancreatobiliary endoscopists attending the meeting (answer rate 87.5%). Biliary cannulation was performed using a guidewire access technique by the majority (77%), usually with a sphincterotome. When cannulation was unsuccessful, precut was the first choice for 70%. NSAIDs were administered routinely for PEP by only 54%; PGW-assisted biliary cannulation was the first choice after failed standard cannulation for a minority of them, and only 27% reported to routinely attempt insertion of a pancreatic stent. High-volume endoscopists (> 150/year) tended to use NSAIDs and to insert a stent in PGW-assisted cannulation less often than low-volume-endoscopists (50 vs. 83.3%, p < 0.01, and 40 vs. 100%, p < 0.01, respectively). Precut was started without prior formal training by more than half of the endoscopists.ConclusionsThere is a pronounced discrepancy between evidence-based guidelines and current clinical practice. This discrepancy is more pronounced in PEP prophylaxis, especially among high-volume endoscopists. Some advanced techniques in ERCP are initiated unsupervised, without any previous formal training.Key messageThere is a significant gap between guidelines and routine clinical practice.

Project description:Investigate success rates of cannulating a 'virgin' papilla during endoscopic retrograde cholangiopancreatography (ERCP) at a tertiary referral centre; determine reasons for failure and propose learnings for consideration in future revision of success benchmarking.Review of all ERCPs recorded on Endosoft database from 2006 to 2012 (n=1862). Specifically, 'virgin' papillae, defined as those with no evidence of prior surgical intervention, stents in situ or sphincterotomy (n=947). Virgin papillae present the most challenging target for endoscopists.Gastroenterology department, St Thomas' Hospital, London.All patients who underwent an ERCP recorded on Endosoft from 2006 to 2012 (n=1134). A proportion of these patients underwent repeat procedures, all considered virgin provided the aforementioned criteria were met.None, retrospective audit and benchmarking exercise.Determine criteria for successful cannulation of a virgin papilla.Overall success of cannulation of a virgin papilla at ERCP was 79.5%, 753 out of a total of 947 virgin papillae cases. Per patient with a virgin papilla, the success rate was 79.7%, 693 out of 869. Eliminating cases with features complicating cannulation increased success rates to 86% and 87%, respectively. Chronic pancreatitis was the single Indication associated with a failed cannulation (OR=3.9, CI 2.1 to 7.1), while biliary stones were significantly associated with a successful cannulation (OR=0.3, CI 0.2 to 0.4). Reasons for failure included patient agitation (OR=27.1, CI 7.9 to 92.7), duodenal stricturing (OR=12.5, CI 5.5 to 28.5), previous anatomy-changing surgery (OR=12.2, CI 3.3 to 45.4), tumour impingement (OR=9.5, CI 4.1 to 22.3) and equipment failure (OR=7.9, CI 1.4=43.5).The Joint Advisory Group's 80% success rate for completion of therapeutic intent must be viewed in light of published difficulty rating scales, if fair comparisons and standards are to be met. This highlights the need for standardised success criterion for ERCP training and accreditation.
