Bethesda Endoscopic Retrograde Cholangiopancreatography Skill Assessment Tool (BESAT)-Based Simulator Training Using a Novel Dry Endoscopic Retrograde Cholangiopancreatography Model Improves Technical Proficiency and Self-Efficacy: A Prospective Study.
Article in DEN open, 2027. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objectives: Endoscopic sphincterotomy (EST) is a high-risk procedure with a steep learning curve. We previously developed a novel dry simulator capable of reproducing bleeding after an inappropriate incision. This study aimed to evaluate the effectiveness of a structured educational program using the simulator within the Bethesda Endoscopic retrograde cholangiopancreatography (ERCP) Skill Assessment Tool (BESAT) framework. Methods: This prospective study implemented a standardized training sequence: (1) preliminary video-based learning; (2) an initial attempt at cannulation, EST, and biliary stone extraction; (3) BESAT-based expert feedback focusing on six key technical tips; (4) a second attempt. The primary outcome was the change in EST success, which is defined by an incision in the 11-12 o'clock direction with appropriate length and no bleeding, before and after feedback. Secondary outcomes were procedure completion, including stone removal within 15 min, and subjective self-assessments of procedural understanding and confidence. Results: Thirty gastroenterology trainees were enrolled. The EST success rate increased from 43.3% to 76.7% ( Conclusions: A structured simulator-based program enables trainees to experience failure and improves simulator-based EST performance with sustained gains in self-efficacy.
