Development of a novel endoscopic suturing simulator: validation and impact on clinical learning curve (with video).
Article in Gastrointestinal endoscopy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
BACKGROUND AND
aimsEndoscopic suturing is a complex skill with broad applications. The aim of this study was to develop and validate a novel endoscopic suturing simulator and scoring system for the purse-string suture pattern.
methodsThis was a prospective study of an endoscopic suturing simulator that consists of a circular opening representing a dilated gastrojejunal anastomosis of Roux-en-Y gastric bypass with 12 small target holes around its circumference. Purse-string suturing is performed in a counterclockwise fashion. Time allotted is 5 minutes, and each successful bite is awarded 10 points. Participants were divided into the novice, intermediate, and experienced groups. Validity evidence based on content, validity evidence based on other variables, and validity evidence based on consequences of testing were assessed.
resultsSeventeen subjects (3 novice, 7 intermediate, and 7 experienced) participated in the study. Validity evidence based on content: The content validity index for realism, relevance, and representativeness was 0.89, 1.00, and 1.00, respectively. Validity evidence based on other variables: The novice, intermediate, and experienced groups scored 30.0 ± 8.2, 57.1 ± 28.1, and 131.2 ± 51.7 (P = .001). Validity evidence based on consequences of testing: The simulator group required 5 ± 5 transoral outlet reduction cases before being able to independently complete an entire purse-string, whereas the non-simulator group required 38 ± 11 clinical cases (P < .0001).
conclusionsThis novel endoscopic suturing simulator seems realistic, relevant, and representative of the clinical suturing experience. In addition, it seems effective at objectively assessing suturing skills and shortening the clinical learning curve.
