Abstract

Introduction

This study describes a stepwise training program to teach a laparoscopic Roux-en-Y gastric bypass (LRYGB). Results of a resident are compared to experienced bariatric surgeons (EBS).

Methods

The resident performed a varying amount of surgical steps and the duration of every step was measured using video analysis. In order to compare the resident’s results to EBS, the average time per step was calculated for 30 procedures.

Results

The total procedure time of LRYGB was 61.15 (± 8.74) min for a novice resident. In comparison, the average of three EBS was 36.22 (± 9.06) min. Creation of the gastric pouch had an average of 12.82 (± 4.08) versus 6.93 (± 2.58) min. Duration of creating the stapled gastrojejunostomy was 7.43 (± 2.11) versus 4.48 (± 2.02) min. Suturing of the gastrojejunostomy was 12.60 (± 3.31) compared to 6.31 (± 2.53) min. Creating the jejunojejunal anastomosis had a duration of 7.12 ( ±2.31) versus 4.22 (± 1.60) min and suturing this anastomosis was 13.93 (± 3.81) compared to 8.51 (± 3.37) min. At the end of the traineeship, the observed progression approximated the skills level of the EBS.

Conclusion

The stepwise LRYGB-training program, analysed in this study, can result in an efficient and safe way to approach the learning curve to the level of the EBS. Within this training program, the total time of the operation is kept low in order to prevent adverse events for the patient and loss of efficiency in the bariatric program. The results of this study could act as a guideline for the development of such training programs.
