Background:
Vertical sleeve gastrectomy (VSG) was originally performed as the first-stage of biliopancreatic diversion with duodenal switch (BPD/DS) for superobesity as a strategy to reduce perioperative complications and morbidity. VSG is now considered a definitive procedure because of its technical simplicity and promising outcomes.
Aims:
To analyze the outcomes of laparoscopic VSG and to compare them with those of single-stage laparoscopic BPD/DS.
Materials And Methods:
A retrospective review of 200 consecutive patients who underwent VSG and BPD/DS between 2008 and 2011.
Results:
A total of 100 patients underwent laparoscopic VSG and 100 patients underwent laparoscopic BPD/DS. The patients in VSG group were older, but gender distribution and body mass index were comparable. Mean operative time for VSG was significantly shorter compared with that of BPD/DS. A single patient in each groups required open conversion. Staple line leak (n = 1) and intraluminal hemorrhage into the newly-created sleeve (n = 1) occurred in the BPD/DS group. Mean length of stay was shorter after VSG (3.1 vs. 3.9 days). At 6 months postoperatively, excess weight loss between the two groups revealed statistically significant difference, favoring BPD/DS.
Conclusions:
Despite promising outcomes and technical simplicity of VSG, BPD/DS provides significantly superior excess weight loss in morbidly obese patients.
