Abstract:
Management of super-super obese patients poses a particular challenge for bariatric surgeons. Many staged algorithms exist for these patients. Essentially all of these involve a lower-risk procedure like sleeve gastrectomy first before a definitive second-stage procedure like gastric bypass or duodenal switch. This study compares our results with 19 mini (one anastomosis) gastric bypass and 56 sleeve gastrectomy in super-super obese patients. Sleeve gastrectomy patients were significantly older. There was no mortality or major complication in either group. There was no minor complication in mini (one anastomosis) gastric bypass group compared to two in the sleeve gastrectomy group. Mini (one anastomsosis) gastric bypass patients experienced significantly higher weight loss compared to sleeve gastrectomy patients at 6 months, 1 year, and 2 years after surgery.
