Five-Year Experience Training Surgeons with a Laparoscopic Simulation Training Program for Bariatric Surgery: a Quasi-experimental Design.
Article in Obesity surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
purposeNearly 200,000 laparoscopic Roux-en-Y gastric bypass (LRYGB) are performed yearly. Reported learning curves range between 50 and 150, even 500 cases to decrease the operative risk. Simulation programs could accelerate this learning curve safely; however, trainings for LRYGB are scarce. This study aims to describe and share our 5-year experience of a simulated program designed to achieve proficiency in LRYGB technical skills. MATERIALS AND
methodsA quasi-experimental design was used. All recruited participants were previously trained with basic and advanced laparoscopic simulation curriculum completing over 50 h of practical training. Ex vivo animal models were used to practice manual and stapled gastrojejunostomy (GJ) and stapled jejunojejunostomy (JJO) in 10, 3, and 4 sessions, respectively. The main outcome was to assess the manual GJ skill acquisition. Pre- and post-training assessments using a Global Rating Scale (GRS; max 25 pts), Specific Rating Scale (SRS; max 20 pts), performance time, permeability, and leakage rates were analyzed. For the stapled GJ and JJO, execution time was registered. Data analysis was performed using parametric tests.
resultsIn 5 years, 68 trainees completed the program. For the manual GJ's pre- vs post-training assessment, GRS and SRS scores increased significantly (from 17 to 24 and from 13 to 19 points respectively, p-value < 0.001). Permeability rate increased while leakage rate and procedural time decreased significantly.
conclusionThis simulated training program showed effectiveness in improving laparoscopic skills for manual GJ and JJO in a simulated scenario. This new training program could optimize the clinical learning curve. Further studies are needed to assess the transfer of skills to the operating room.
