Washington: Two new studies have found that gastric bypass surgery lead to better long-term results including greater weight loss, resolution of diabetes and improved quality of life compared with sleeve gastrectomy and "lap-band" surgery.The most common surgical procedure for treating diabetes in the United States is the laparoscopic Roux-en-Y gastric bypass, more commonly referred to as gastric bypass surgery.
Also resolution or improvement of type 2 diabetes was significantly better after gastric bypass compared to lap-band.Early complications (within the first 30 days post-surgery) were higher in the gastric bypass group than the lap-band group.However, the rate of re-operation was higher in lap-band patients compared to gastric bypass patients. In a second report, Wei-Jei Lee, of the Min-Sheng General Hospital, Taiwan, and colleagues conducted a double-blind randomized controlled trial of 60 moderately obese patients between the ages of 30 and 60, who had poorly controlled type 2 diabetes after conventional treatment. Between September 2007 and June 2008, half of the patients were randomized to undergo gastric bypass with duodenum exclusion and half were randomized to have a sleeve gastrectomy without duodenum exclusion.Overall, 42 patients had remission of type 2 diabetes 12 months after surgery. However, this resolution was significantly greater for gastric bypass patients than sleeve gastrectomy patients.Both groups also had significant weight loss at the one- and three-month post-surgery follow-up, but gastric bypass patients had better weight loss results at the six- and 12-month follow-ups.The studies appeared in the February issue of Archives of Surgery, one of the JAMA/Archives journals.
