Brief Summary:

Although intensive medical treatment of diabetes has clearly been demonstrated to be worthwhile, it has not been a total success in diabetes treatment for a variety of reasons including lack of response to medication. Diabetes has been well demonstrated as a co-morbidity illness of obesity patients. In observation, with exclusion stomach and duodenum of bariatric surgery (gastric bypass), most morbidly obese patients (about 80%) with diabetes had a significant improved of sugar control. Base of this observation, we will try to find out the role surgical intervention (gastric bypass & sleeve gastrectomy) in obese-related diabetes.

Condition or disease	Intervention/treatment	Phase
Type II Diabetes Mellitus	Procedure: gastric bypass; Procedure: sleeve gastrectomy	Phase 4

Detailed Description:

In observation, with exclusion stomach and duodenum of bariatric surgery (gastric bypass), most morbidly obese patients (about 80%) with diabetes had a significant improved of sugar control. Base on this observation, we will try to find out the role surgical intervention (gastric bypass and sleeve gastrectomy) in obese-related diabetes. With restriction of stomach volume and with or without duodenal exclusion, this randomized trials will find out the role of duodenal exclusion and the role of Ghrenin in obese-related type II DM patients. The initial observation of previous morbidly obese patients with type II DM, the DM seems a chronic disease which could be treated or controlled by surgical intervention, that's what we try to know more.
