Abstract

Purpose: Nearly 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 methods: A 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.

Results: In 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.

Conclusion: This 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.
