Long-term mortality after bariatric surgery

Bariatric surgery results in significant weight loss and improvement in obesity-related comorbidities. These benefits ultimately lead to improved health and increased survival. The current data show that the long-term mortality after adjustable gastric banding (AGB) decreased from a range of 2.5-10.6 % in nonsurgical controls to a range of 0-3.7 % in surgical patients. Vertical sleeve gastrectomy (VSG) also demonstrated low long-term mortality, although at relatively shorter term. Biliopancreatic diversion (BPD) has a reported a mortality of 0.2-8 % at mean follow-up of 2-12 years. Long-term mortality following Roux-en-Y gastric bypass (RYBG) ranged from 1.8 to 9 % and represented a significant reduction compared to mortality in obese individuals who did not undergo surgery (4.1 to 28 %). In studies which included multiple operations, the overall long-term mortality rate for bariatric surgery ranged from 0.68 to 5 % and was significantly lower than control mortality of 6.17-6.3 % at 5-11 years after surgery. Current data seem to clearly support that bariatric surgery significantly reduces obesity-related mortality.
