Laparoscopic jejunoileal side-to-side anastomosis for the treatment of type 2 diabetes mellitus in Chinese patients with a body mass index of 24-32 kg/m 2 .

Objective: Laparoscopic jejunoileal side-to-side anastomosis (LJISSA) is an upcoming procedure that offers good metabolic improvement without causing significant malabsorption. The objective of this study was to evaluate the results of this novel procedure for the control of type 2 diabetes mellitus (T2DM) in patients with a body mass index (BMI) of 24u32 kg/m (2). Materials and Methods: Fifty-seven patients with T2DM who underwent LJISSA between February 2010 and May 2013 were recruited in this study. Data collected included fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), 1 h postprandial C peptide (1 h C-P), and glycosylated hemoglobin (HbA1c). Results: Postoperatively, glycemic parameters (FBG and 2 h PBG, HbA1c and 1 h C-P) improved in all 57 patients. At 12 months, 34 patients had a remission of diabetes, and the remaining 23 patients showed a significantly decreased requirement for oral hypoglycemic agents. The patients with a BMI of 28u32 kg/m (2) had significant weight loss of between 7.8% and 20% (P < 0.05), whereas weight loss was not significant in those with a BMI of 24u28 kg/m (2). The group achieving remission had a higher BMI (28u32 kg/m (2)), shorter duration of diabetes (<10 years), and higher stimulated C-P (4 ng/mL). These three factors may be the predictors of diabetes resolution at 12 months. Conclusion: LJISSA seems to be a promising procedure for the control of T2DM. A multicenter study with a larger number of patients and a longer follow-up period is needed to substantiate our preliminary findings.
