Objective:
To evaluate the outcomes after laparoscopic gastrointestinal surgery for patients with obesity and type 2 diabetes mellitus(T2DM).
Methods:
From June 2003 to June 2010, 219 patients underwent laparoscopic gastrointestinal surgery for obesity and T2DM, including laparoscopic adjustable gastric banding(LAGB, n=201), laparoscopic mini gastric bypass(LMGB, n=13), and laparoscopic sleeve gastrectomy(LSG, n=5). Clinical data were analyzed retrospectively.
Results:
The mean body mass index(BMI) of patients who received LAGB was 37.9 kg/m(2), and decreased to 32.4 kg/m(2) at 6 months and to 29.7 kg/m(2) at 12 months. In 43 patients who had concurrent T2DM, 11(25.6%) showed clinical partial remission(CPR) and 16(37.2%) clinical complete remission (CCR). Postoperative complications occurred in 26 patients(12.9%). The mean BMI of patients undergoing LMGB was 34.7 kg/m(2), and decreased to 31.6 kg/m(2) at 6 months and 26.9 kg/m(2) at 12 months after surgery. Ten patients had T2DM before operation, of whom 2(20.0%) had CPR and 7(70.0%) CCR postoperatively. Postoperative complications occurred in 2 patients(15.4%). The mean BMI of patients who underwent LSG was 43.8 kg/m(2), and was reduced to 38.1 kg/m(2) at 6 months and 34.3 kg/m(2) at 12 months after operation. Three patients were diagnosed with T2DM before operation. One patient (33.3%) had CPR and 1(33.3%) reached CCR after operation. There was 1(20.0%) patient who developed complication. No perioperative death occurred.
Conclusion:
Laparoscopic gastrointestinal surgery may result in satisfactory weight loss and clinical remission of T2DM with few complications.
