Development and preliminary evaluation of a novel low-cost endoscopic retrograde cholangiopancreatography simulator with electrocautery training capability: a proof-of-concept study from India.

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
backgroundEndoscopic retrograde cholangiopancreatography (ERCP) requires extensive training, with around 350-400 supervised cases being required for proficiency. Existing simulators face costs, limited availability, and limited realism. Therefore, we developed and preliminarily evaluated a minimal ERCP training model that incorporated electrocautery capabilities.
methodsA five-phase development process was employed, including needs assessment, iterative prototyping with material optimization, technical performance testing across 50 training sessions, comparative analysis against existing simulators, and preliminary expert evaluation by eight experienced endoscopists (mean ERCP experience: 12.3±4.2 years). The primary outcomes included verification of functional capability, cost analysis, durability assessment, and expert ratings on 5-point Likert scales for realism and educational value.
resultsThe simulator successfully achieved biliary cannulation in 48/50 sessions (96.0%), supported needle knife precut training with functional electrocautery, and demonstrated compatibility with C-arm fluoroscopy, providing adequate contrast visualization. The total material cost per unit was 47.32 United States dollars (USD), compared to 180,000-250,000 USD for commercial virtual reality simulators. The model withstood 50 sessions without structural failure (onion bulb replacement was required every 8.2±1.4 precut attempts). Expert ratings indicated high scores for anatomical realism (4.1±0.6), tactile feedback (3.9±0.7), and educational value (4.4±0.5).
conclusionsThis novel, low-cost ERCP simulator demonstrated technical feasibility and face validity. This proof-of-concept requires formal prospective validation studies to establish construct validity, concurrent validity, and educational effectiveness through trainee learning outcomes before conclusions regarding the impact on clinical training can be drawn. The innovation addresses significant accessibility barriers but represents preliminary evidence that requires formal educational validation.
