Abstract

Introduction

Laparoscopic sleeve gastrectomy plus duodenojejunal bypass (LSG-DJB) has emerged as an alternative bypass surgery. Despite its potential benefits, the technical challenges of the procedure have limited its adoption. This study aims to present the learning curve for LSG-DJB and explore potentially beneficial technical modifications for the standardization of the procedure.

Methods

The study retrospectively analyzed 100 patients who underwent LSG-DJB as a primary procedure from July 2014 through September 2021. Baseline characteristics, weight loss outcomes, remission of metabolic diseases, and perioperative complications were assessed. The operative time was analyzed across both time trends and anastomosis type subgroups.

Results

At 1-year follow-up after LSG-DJB, the mean %total weight loss and the mean BMI loss were 25.38 ± 8.58% and 9.38 ± 4.25 kg/m2, respectively. Remission rates for type 2 diabetes, hypertension, and dyslipidemia were 72.0% (67/93), 84.1% (37/44), and 70.3% (52/74), respectively. In the analysis of operative time, the learning curve exhibited a plateau after 25 cases. The mean operative time was 136.00 ± 21.64 min in the stapled anastomosis group, and 150.62 ± 25.42 min in the hand-sewn anastomosis group.

Conclusion

The learning curve for LSG-DJB plateaued after 25 cases. In the LSG-DJB procedure, stapled duodenojejunal anastomosis is feasible and achieves similar outcomes to the hand-sewn method.
