PG - 1172-1179 LID - 10.1007/s00464-016-5087-3 [doi] AB - OBJECTIVES: To evaluate the Roux-en-Y gastric bypass (GBP) procedure for patients suffering from type 2 diabetes mellitus (T2DM) with body mass index (BMI) <28 kg/m(2). METHODS: Thirty-one patients suffering from T2DM were selected to undergo laparoscopic Roux-en-Y gastric bypass surgery and were enrolled at Beijing Shijitan Hospital between November 2012 and December 2014. The fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), C-peptide, fasting insulin (FINS) and glucagon-like peptide-1 (GLP-1) of all patients were measured before and at 1, 3, 6 months after surgery. The results were compared and analyzed. RESULTS: Thirty-one patients suffering from T2DM successfully underwent GBP surgery (a mean age of 46 years), 14 were male and 17 were female. Among them, 7 patients had hypertriglyceridemia (HTG). The patients were followed up for 6 months. No major complications were found. The average BMI was 26.5 +/- 1.4 kg/m(2) before surgery. The average levels of FPG, HbA1c, C-peptide, FINS of all patients were statistically decreased after surgery, respectively, compared to those before surgery (P < 0.05). However, the mean GLP-1 of all patients was statistically increased after surgery compared to that before surgery (P < 0.05). At 6 months after surgery, 22 patients (71 %) achieved complete remission of T2DM with HbA1c < 6.5 %, 7 patients (23 %) gained partial remission of T2DM with 6.5 %
