Abstract
INTRODUCTION: Whereas sleeve gastrectomy (SG) in its beginnings was mainly performed to treat super-obesity, it has become as popular as gastric bypass in the treatment of obesity of any class. In contrast to this, the persisting problems of early staple line leaks and poor long-term results of SG regarding weight loss and new onset of gastroesophageal reflux have become increasingly obvious. The mini-gastric bypass (MGB) with its low complication rates and possibly better long-term results may be a good alternative to SG, especially in super-obesity. METHODS: In this context, two groups of mostly super-obese patients (SG and MGB) of a single bariatric center were retrospectively analyzed and compared for perioperative and early postoperative outcomes. RESULTS: Between August 2007 and March 2015, 169 patients underwent MGB, while 118 patients were operated by SG. Both groups were comparable for BMI at baseline (MGB = 54.1 kg/m2 vs. SG = 54.6 kg/m2, p = 0.657). Mean operation time (81.7 vs. 112.1 min, p < 0.0001) as well as hospital stay was lower in the MGB-group (4.5 vs. 7.2 days, p < 0.0001). Perioperative (30 days) mortality was 0 % in MGB versus 0.8 % in SG (one patient). Perioperative complication rate was also lower in the MGB-group (3.0 vs. 9.3 %, p = 0.449). %EWL was significantly better after 1 year in MGB: 66.2 % (±13.9 %) versus 57.3 % (±19.0 %) in SG (p < 0.0001), as well as BMI which was 34.9 kg/m2 (±4.8 kg/m2) in MGB versus 38.5 kg/m2 (±8.6 kg/m2) in SG (p = 0.001). CONCLUSIONS: MGB achieved superior weight loss at 1 year and had a lower 30-day complication rate in comparison with SG for super-obese patients. Thus, MGB might be superior to SG regarding the treatment of super-obesity.
