ABSTRACT
Recently, several scoring systems have been proposed to predict remission from type 2 diabetes mellitus (T2DM) after metabolic surgery. The ABCD score was compared to the individualized metabolic surgery (IMS) score in terms of the prediction of long-term T2DM remission; however, which of the two scoring systems is better remains controversial. Thus, Three East Asian countries Metabolic Surgery (TEAMS), which has been organized as a study group since 2016, is conducting a retrospective, international, multi-institutional study to compare the two scoring systems in East Asian obese patients after metabolic surgery. The primary study objective is to compare the ABCD score with the IMS score at 3 and 5 years after sleeve gastrectomy (SG), Roux-en-Y gastric bypass, one anastomosis gastric bypass and SG with duodenojejunal bypass. The secondary objectives include evaluating patients who were good candidates for SG, and adjusting the IMS scoring system for East Asian patients.
