Abstract
BACKGROUND:
Obesity is associated with cardiovascular risk factors such as lipid levels and increased levels of C-reactive peptide (CRP). We hypothesized that duodenal switch (DS) would show equivalent or superior risk reduction compared with standard bariatric surgeries.
METHODS:
Patients underwent DS, sleeve gastrectomy (SG), or gastric bypass (GB) over a 2-year period. Body mass index (BMI), lipid panel, and CRP were measured preoperatively and then 3, 6, and 12 months postoperatively.
RESULTS:
A total of 130 patients were identified; 42 underwent DS, 40 underwent SG, and 48 underwent GB. All groups had similar sex and comorbidity profiles, but the mean preoperative BMI was greatest in the DS group (mean = 52). At all intervals weight loss was greater in the DS group (P < .01), with a final BMI of 31 for the DS group, 31 for the SG group, and 28 for the GB group. Cholesterol and low-density lipoprotein showed significantly greater improvement at all time points with DS compared with SG and GB (P < .01). Baseline CRP levels among DS patients were double that of SG and GB, but rapidly declined to equivalent levels by 3 months and normalized in 79%.
CONCLUSIONS:
The DS procedure resulted in a superior reduction in cardiovascular and proinflammatory risk markers compared with GB and SG.
