Factors associated with relapse of type 2 diabetes mellitus after laparoscopic sleeve gastrectomy in Japanese subjects: a subgroup analysis of J-SMART study

Introduction: Laparoscopic sleeve gastrectomy (LSG) for morbidly obese patients often result in remission of type 2 diabetes (T2DM), but diabetes relapses in some of those patients. The frequency of T2DM relapse in Asians and the factors involved have not been adequately investigated. Methods: The J-SMART study was conducted on 322 Japanese subjects with body mass index (BMI) ≥ 32 kg/m2 who underwent LSG at 10 accredited centers in Japan between 2011 and 2014. Of these, 82 T2DM subjects with diabetes in complete or partial remission at 1 year after LSG and followed postoperatively for 5 years were included in the subgroup analysis, and classified into two groups: diabe tes remission maintained and diabetes relapse. Results: The mean age of all included subjects was 49.2 years, median BMI was 41.5 kg/m2, and median was HbA1c 6.7%. Compared with the diabetes remission maintained group, the diabetes relapse group at 5 years after LSG had significantly higher preopera tive HbA1c, number of antidiabetic medications, and high-density lipoprotein cholesterol level; and lower BMI and homeostasis model assessment-beta cell function (HOMA-β). As many as 83.0% of the subjects were able to achieve HbA1c
