AbstractBariatric surgery has been shown to be effective in achieving and maintaining weight change and reducing obesity-related comorbidities. Recent reports have shown that sleeve gastrectomy could have similar resolution rates of the metabolic syndrome than Roux-Y bypass after a short-term follow-up of 1 year. Most surgeons calibrate the sleeve with 32-Fr to 40-Fr bougies. There is little mid- and long-term information available about the evolution of these comorbidities with this procedure and with calibration of the sleeve with a 50-Fr bougie. A retrospective study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy, calibrated with a 50-Fr bougie, as bariatric procedure between October 2007 and September 2009 was performed. Mean excessive body mass index loss was 76.9 per cent after 1 year and 79.9 per cent after 2 years. After surgery, 83.3 per cent of patients with Type 2 diabetes mellitus discontinued their hypoglycemic medication at 1 month. All the patients with hypertension discontinued antihypertensive drugs at 6 months. One hundred per cent of patients with hypertriglyceridemia discontinued their hypolipidemic drugs at 3 months. Glucose levels decreased significantly 3 months after surgery (mean reduction of 24.7 mg/dL; 95% confidence interval [CI], 8.8 to 40.7; P = 0.003). Triglyceride levels decreased 3 months after surgery (mean reduction of 54.4 mg/dL; 95% CI, 22.8 to 86.1; P = 0.004). High-density lipoprotein (HDL) cholesterol increased significantly after 12 months (increase of 16.7 mg/dL; 95% CI, 11.7 to 21.7; P < 0.001). The changes observed were maintained 24 months after surgery. Sleeve gastrectomy, calibrated with a 50-Fr bougie, significantly reduced glucose and triglyceride levels and the cardiovascular risk predictor triglyceride/HDL ratio and increased HDL levels after surgery and maintained them under normal ranges for at least 2 years.
