In Reply We interpret the letter from Gagner regarding our 26-year report of revisional surgery in the Swedish Obese Subjects (SOS) study1 as yet another contribution to the current dispute of pros and cons of gastric bypass (GBP) vs sleeve gastrectomy. Gagner is a strong advocate of sleeve gastrectomy,2 and he predicts that this surgical method will be a “mass treatment for the global epidemic of severe obesity and diabetes.”3 However, the SOS study was started more than 30 years ago, and sleeve gastrectomy has only been widely used during the last decade. Thus, the results of the SOS study cannot contribute to the choice between these 2 procedures.
