Authors' recommendations: Summary The available data suggests that weight losses are more pronounced with gastric bypass and sleeve gastrectomy, and less so with AGB. AGB is associated with fewer serious adverse side effects, but has a higher risk of slippage/dilation and procedure conversion/reversal compared with the other techniques. There is some evidence to suggest that compared with standard care, certain bariatric procedures are cost-effective methods of reducing diabetes complications in moderately and severely obese people. However, direct trials of clinical effectiveness are needed before the relative cost effectiveness of the procedures can be established. From this initial scope of the literature, it is not clear which bariatric procedure is suited to which patient characteristic, or when in the diabetes illness trajectory bariatric surgery is most successful in improving or resolving T2DM. It is also not clear whether the improvements in diabetes are maintained beyond 10 years.
