Small case series suggest bariatric surgery may be effective treatment for diabetes in patients who do not meet criteria for morbid obesity (BMI < 35 kg/M2), but large multi-institutional series, which allow better assessment of the safety / efficacy of treatment, have not been reported.
Data from 66,264 research-consented patients with a surgery encounter in BOLD were queried to identify patients with BMI > 30 but < 35 kg/m2 (1.2%, n=794) and diabetes (DM) requiring any medication (29% of group).
235 patients met inclusion criteria. The 2 most common procedures (adjustable gastric banding AGB, n=109 and gastric bypass, n=109) were compared. Laparoscopic access was utilized in 92% of procedures. Gender (77% female), race (80% Caucasian), and age (mean 52.6 + 10.4 yrs) did not differ between procedure groups.
Table: Data reported at baseline (BL) and at intervals < 12 months following surgery. (*p<0.05 vs. BL, α p<0.05 bypass vs. band)
Remission (cessation of medications) of DM was reported in 47.8% of patients within 6-12 months of surgery. Gastric bypass provided superior weight loss and DM remission, but demonstrated more frequent complications (90-day AE: 12% vs. 3%, p<0.05). No mortalities were reported. The data suggest successful surgical treatment of diabetes in patients not meeting criteria for morbid obesity. Gastric bypass provides more effective early treatment for DM within 6-12 months.
