Abstract

Background

Laparoscopic sleeve gastrectomy (LSG) is a surgical technique that treats morbid obesity.

Methods

Consecutive patients with morbid obesity treated by LSG at our department were evaluated. Patients enrolled in the study were randomized into group I (LSG begins the division 2 cm from the pylorus) and group II (LSG begins the division 6 cm from the pylorus). The primary outcome measure was the percent of excess weight loss (% EWL); secondary outcomes included postoperative morbidity and mortality and improvement of comorbidity.

Results

One hundred five patients (79 (75.2 %) were females) were randomized into two groups of (GI) 52 patients and (GII) 53 patients. In group I, the mean % EWL was 51.8 ± 13.9, 63.8 ± 16.1 and 71.8 ± 12; however, in group II, the mean % EWL was 38.3 ± 10.9, 51.9 ± 13.6 and 61 ± 11.1 at 6, 12, and 24 months, respectively (P = 0.0001, 0.0001, 0.003). There was weight regain after 2 years in five patients in group II and only one patient in group I (P = 0.09). There was no significant difference between both group as regards gastric leakage, vomiting or GER. There was significant improvement in comorbidity after LSG in both groups, but no significant difference between them. Hospital mortality occurred in group II in one case as a result of gastric leakage.

Conclusions

LSG is a safe and effective procedure with good short-term outcome. Increasing the size of the resected antrum is associated with better weight loss without increasing the rate of complications significantly.
