Surgery for obesity.
Abstract
PURPOSE OF REVIEW: Bariatric surgery today is the only effective therapy for morbid obesity. Commonly performed procedures include adjustable gastric banding and vertical banded gastroplasty, variations of the Roux-en-Y gastric bypass, biliopancreatic diversion or duodenal switch, and mixed procedures. This review discusses key issues in the surgical management of morbid obesity. RECENT FINDINGS: The two most common bariatric procedures performed worldwide are laparoscopic adjustable gastric banding and laparoscopic Roux-en-Y gastric bypass. Controversy exists regarding the best surgical procedure. Weight loss decreases according to the procedures performed in following decreasing order: biliopancreatic diversion, Roux-en-Y gastric bypass, vertical banded gastroplasty, adjustable gastric banding. Concerning the complications and quality of life, there is no single operation for morbid obesity without drawbacks. Cost-effectiveness analyses have demonstrated that bariatric surgery is cost effective at less than 50,000 US dollars/quality-adjusted life years. SUMMARY: According to current opinion, gastric restrictive procedures (adjustable gastric banding, vertical banded gastroplasty) are generally considered safe and quick to perform, but the long-term outcome and quality of life have been questioned. By contrast, the long-term efficacy of adjustable gastric banding can be improved by the development of new band devices. More complex bariatric procedures, such as the Roux-en-Y gastric bypass or biliopancreatic diversion, have a greater potential for serious perioperative complications but are associated with good long-term outcome in terms of weight loss combined with less dietary restriction.
