Abstract: The curative effect of surgical treatment for obesity and type 2 diabetes mellitus has been internationally re cognized. In mainland China, the number of the minimally invasive gastric volume reduction surgery has been increased from 110 cases in 2008 to 2000 cases in 2012. While some of the patients suffered from poor curative effects or severe postoperative complications due to lack of unified standard treatment guidelines. Authoritative statistical agencies and the Chinese clinical database has not been formed till now, therefore the specification and promotion of Chinese surgical treatment standards for obesity and type 2 diabetes mellitus is imperative.
