[Application of revisional operation in failure and complication of bariatric surgery].

For the vast majority of morbidly obese patients, surgical treatment remains the only effective way proven to maintain weight loss. Currently adjustable gastric banding (AGB), sleeve gastrectomy (SG), Roux-en-Y gastric bypass(RYGB) are the methods which are recognized as safe, reliable, effective for weight loss, and has been widely used. Along with the increase in the volume of bariatric operations, patients whose primary bariatric operation is not ideal and who need revision surgery are also increasing. Weight loss failure and postoperative complications are two of the main indications for revisional operation. A series of data indicate that revisional operation is an effective treatment for unsuccessful weight loss and complications of primary operation. Surgeons should choose reasonable, correct operation refer to the initial bariatric operation and results. For most patients, the benefits overweigh the risks.
