Abstract

Background

Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been proven to be effective on treating type 2 diabetes mellitus (T2DM) in severely obese patients, but whether LRYGB surgery should be performed in obese class I patients is controversial.

Materials and Methods

A retrospective study of 3-year bariatric and metabolic outcomes in different obese class T2DM patients who underwent LRYGB was conducted to compare the effectiveness of LRYGB in obese class I patients with that in obese class II/III patients in a Chinese T2DM population.

Results

Totally, 58 patients with class I obesity and 45 patients with class II/III obesity were enrolled in this study. Major complications included two cases of incomplete intestinal obstructions and one anastomotic leak. The remission rates of T2DM were 70.6% in obese class I group and 77.8% in obese class II/III group at 1 year after surgery and 55.6 versus 64.3% at 3 years (all P > 0.05). Logistic regression analysis showed that higher waist circumference, lower fasting plasma glucose, and higher FCP at 2 h of OGTT were independently associated with diabetes remission at 1 year after surgery. At 1 year and thereafter, the percentage of excess weight loss was significantly greater in obese class II/III patients. At 3 years, body mass index was not significantly different between the two groups, and the obese class I patients had high recurrence rates of hypertension and hyperuricemia.

Conclusions

LRYGB surgery is feasible, safe, and effective in Chinese obese class I patients with T2DM.
