Research question: To compare long term diabetes outcomes in patients undergoing sleeve gastrectomy as compared to controls who undergo nonsurgical diabetes care.
Methods: We reviewed medical records of veterans between 18 and 80 years of age with type 2 diabetes undergoing sleeve gastrectomy at a VA medical center in a major metropolitan area. Primary study outcomes included measures of diabetes control including HbA1C and BMI. Secondary outcomes such as total and LDL cholesterol, hospitalizations and mortality were also assessed. Data from surgery patients were compared to data from diabetic controls that did not undergo surgery using descriptive analyses, t-tests , and repeated measures ANOVA.
Results: Data from charts of 30 surgery patients and 23 controls were analyzed from 2010 to 2013. Most of the subjects enrolled were males (96%) with an average age of 57 years (range 29-80 years) . The median BMI at baseline was 41 (range 36-60) kg/m2 and median Hba1c was 7.3. There was a significant improvement in BMI and Hba1c in surgery patients over one year follow up; improvements were sustained through the end of two years after surgery. Mean BMI decreased from 41 to 34 over two years ( P<0.001) and mean Hba1c decreased from 7.25 to 5.98 (P<0.001). Similar outcomes were not seen in controls during the study period. Differences in these outcomes between surgery patients and controls were significant over short term and long term follow up (P<0.001). No changes were seen in total cholesterol or LDL cholesterol for surgery patients. However, it was noted that the changes in outcomes plateau after the first year of surgery.
Discussion: It is interesting to note that sleeve gastrectomy may offer better diabetes control and improved outcomes compared to patients who follow medical care only. However, the improvement in outcomes in surgery patients may not be a permanent solution for diabetes outcomes.
Conclusion: Sleeve gastrectomy is effective in improving diabetes outcomes in veterans as compared to those receiving nonsurgical diabetes care.
