Metabolic surgery has become increasingly accepted for the treatment of type 2 diabetes (T2D). However, there is limited evidence regarding the optimal candidate and surgical procedure. Although a new individualized metabolic surgery (IMS) score was recently proposed for procedure selection, it has yet to be validated. To validate the IMS score with regard to remission of T2D after metabolic surgery and compare it with the age, body mass index, C-peptide level, and duration of T2D (ABCD) score. Hospital-based bariatric center. A total of 310 T2D patients who underwent gastric bypass and sleeve gastrectomy at an academic center in Taiwan and had a minimum 5-year follow-up (2004–2012) were examined for the predictive power of complete remission using the IMS and the ABCD scoring systems. At the 5-year follow-up, weight loss was 27.5%, with mean body mass index decreasing from 37.8 to 27.9 kg/m2, mean glycated hemoglobin decreased from 8.6% to 6.1%, and prolonged remission of T2D achieved in 224 (72.3%) T2D patients. Remission rates were higher in patients who underwent gastric bypass than in those who underwent sleeve gastrectomy (73.6% versus 66.1%; P = .04), regardless of T2D severity, and were 96%, 68%, and 16% in patients with IMS mild, moderate, and severe scores, respectively. Although both scores predicted the success of surgery, the ABCD was better in patients with IMS moderate scores. Metabolic surgery is an option for T2D patients with obesity. The ABCD score may be better at predicting T2D remission after metabolic surgery compared with the IMS score.
