Is sleeve gastrectomy as effective as gastric bypass for remission of type 2 diabetes in morbidly obese patients?

We did not find any significant differences in weight loss or T2DM resolution between the 2 techniques. Our results highlight that 1 of the mechanisms implicated in T2DM remission after bariatric surgery is weight loss. The role of other factors, such as incretins, that we have not studied cannot be ruled out and should be analyzed further.
