Abstract
PURPOSE: Recently, more than 10 models have been developed to predict remission of type 2 diabetes mellitus (T2DM) after metabolic surgery. The ABCD score was compared to the individualized metabolic surgery (IMS) score in terms of prediction of T2DM remission, but which of the two scoring systems is better remains controversial. METHODS: Patient data from 463 obese East Asian patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), or SG with duodenojejunal bypass (SG-DJB) as a primary operation and were followed for at least 3 years were retrospectively collected from 24 institutions. The correlation between the ABCD and IMS scoring systems and the discrimination power of the models was evaluated. The cut-off point for the IMS stage of T2DM severity was also revised to adjust the scoring system to obese East Asian patients. RESULTS: The two scoring systems were significantly well correlated. The IMS scoring system showed significant differences in T2DM remission rates between the procedures in the moderate stage, but the ABCD score showed no significant differences in each category. The discrimination power of the IMS score was comparable to that of the ABCD score at both 3 and 5 years. The revised IMS scoring system showed that SG-DJB had significantly higher T2DM remission rates in the moderate stage at 5 years than RYGB or SG. CONCLUSION: IMS score may be comparable to ABCD score to predict T2DM remission in obese East Asian patients. The revised IMS scoring system may also select candidates for SG or SG-DJB.
