Sleeve gastrectomy with duodenojejunal end-to-side anastomosis in the treatment of type 2 diabetes: the initial experiences in a Chinese population with a more than 4-year follow-up.

BACKGROUND

Gastric bypass has been thought to be associated with a risk of gastric cancer, particularly in Asia. Sleeve gastrectomy with duodenojejunal end-to-side anastomosis (SG-DJESA) was suggested to be a better-designed procedure to avoid this risk, and it also has other advantages.

OBJECTIVE

We aimed to evaluate the clinical efficacy and feasibility of SG-DJESA in the treatment of nonobese patients with type 2 diabetes (T2D).

SETTING

University Hospital, China.

METHODS

We present prospective data from 7 consecutive T2D patients with gastric precancerosis who underwent SG-DJESA from December 15, 2011 to June 8, 2013. The group had a mean body mass index of 27.7 kg/m2. The glycometabolic parameters, including fasting plasma glucose, 2-hour postprandial plasma glucose, fasting insulin, fasting C-peptide, glycated hemoglobin, lipometabolic parameters, and anemia-related indicators were collected at baseline and at 1, 3, 6, 12, 24, and 48 months postoperatively. Remission was defined according to the "outcome reporting standards" conducted by the American Society for Metabolic and Bariatric Surgery.

RESULTS

Along with a decrease in antidiabetic medication requirements, body mass index, fasting plasma glucose, 2-hour postprandial plasma glucose, and glycated hemoglobin decreased significantly at each postoperative time point, compared with the preoperative baseline (P<.05, respectively). Four patients (4/7, 57.1%) achieved a complete remission of T2D at 12 months and maintained remission at the 4-year follow-up time; 1 patient (1/7, 14.3%) achieved a partial remission at 6 months but had recurrence at 12 months postoperatively; and the other 2 patients (2/7, 28.6%) achieved improvement during the follow-up time. There were no deaths during the follow-up period. One patient had a postoperative anastomotic bleed and recovered under conservative treatment. Another patient had iron deficiency anemia 8 weeks after surgery and recovered after taking an oral iron supplement for 1 month. No other serious perioperative complications or postoperative malnutrition occurred.

CONCLUSIONS

SG-DJESA is an effective and safe procedure for nonobese patients with T2D and could be recommended as a treatment option for T2D patients with gastric precancerosis. A larger sample size may be required for better evaluation.
