Summary
This study demonstrates that a simulated training program effectively improves laparoscopic skills for gastric bypass surgery. The program accelerates the learning curve for surgeons, enhancing proficiency in key surgical techniques.
Area of Science:
- Surgical Education
- Minimally Invasive Surgery
- Medical Simulation
Background:
- Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a common bariatric procedure with a significant learning curve.
- High volume of LRYGB procedures necessitates efficient and safe training methods.
- Current LRYGB training programs are limited, highlighting the need for simulation-based approaches.
Purpose of the Study:
- To describe a 5-year experience with a simulated training program for LRYGB.
- To assess the effectiveness of simulation in developing proficiency in LRYGB technical skills.
- To evaluate skill acquisition in manual and stapled gastrojejunostomy (GJ) and jejunojejunostomy (JJO).
Main Methods:
- Quasi-experimental design involving 68 trainees over 5 years.
- Utilized ex vivo animal models for practicing manual and stapled GJ and JJO.
- Assessed skill acquisition using Global Rating Scale (GRS), Specific Rating Scale (SRS), procedural time, and leakage rates.
Main Results:
- Significant improvements in GRS and SRS scores for manual GJ post-training (p < 0.001).
- Increased permeability and decreased leakage rates and procedural time for manual GJ.
- Successful skill acquisition demonstrated in simulated gastrojejunostomy and jejunojejunostomy.
Conclusions:
- The simulated training program effectively enhances laparoscopic skills for LRYGB procedures.
- Simulation offers a viable method to optimize the clinical learning curve for bariatric surgeons.
- Further research is required to validate skill transfer from simulation to the operating room.
