Experience in laparoscopic sleeve gastrectomy for morbidly obese Taiwanese: staple-line reinforcement is important for preventing leakage

Abstract

Background: Laparoscopic sleeve gastrectomy (LSG) is a promising procedure for the surgical treatment of morbid obesity. We report our 2-year experience with LSG and specifically evaluate the importance of staple-line protection to prevent leakage after the laparoscopic procedure.

Methods: One hundred eighteen consecutive patients with BMI > 30 who underwent LSG from January 2006 to February 2009 were included in our study. There were 88 women and 30 men with a mean age of 33.2 ± 9.6 years and a mean BMI of 38.0 ± 6.4 kg/m(2). The first 40 patients (group 1) underwent the operation without any reinforcement procedure and the other 78 patients received reinforcement of the staple-line (group 2). Data including demographics, hospital stay, blood loss, operative time, complications, excess weight loss percentage (EWL%), and gastrointestinal quality of life index (GIQLI) were collected prospectively for evaluation.

Results: The overall mean operative time was 118.5 ± 37.0 min, mean blood loss was 56.8 ± 56.7 ml, mean hospital stay was 5 ± 3 days. The mean EWL% at 12 and 24 months was 81.5 and 76.0%, respectively. The overall leakage rate was 3.39% (4/118). All leakage occurred in group 1 patients, with a leakage rate of 10% (4/40). Mean preoperative GIQLI was 98.7, and the postoperative GIQLI were 116.4, 115, 112.4, and 97.6 at 3, 6, 12, and 24 months, respectively.

Conclusions: LSG is an effective obesity treatment to achieve significant weight loss after 24 months. Staple-line reinforcement is strongly recommended for laparoscopic sleeve gastrectomy to decrease complications.
