| Changes in Lipid Profile after Biliopancreatic Diversion Gastric Bypass Bariatric operations have varying degrees of effectiveness and different mechanisms of action. Our objective was to evaluate the efficacy of the biliopancreatic diversion stomach bypass (BPD) in reduction of weight and serum lipids. Method A prospective study was conducted with follow-up from 12 to 72 months (average 39.4 months) of 58 patients with morbid obesity (10 men, 48 women, mean BMI 49.4 kg/m2). Their lipid levels were generally normal or slightly high. All the patients were subjected to subtotal gastrectomy and BPD with jejunoileostomy 50 cm proximal to the ileocecal valve, and they were instructed to maintain the same hypocaloric diet as before biliopancreatic diversion bypass. Serum lipoproteins and apolipoproteins B and A1 were measured before biliopancreatic diversion and every 6 months during follow-up. Results Early and very significant reduction of total cholesterol (32.8%), LDL (46.3%), total cholesterol/HDL ratio (29.7%) and apolipoprotein B (37%), with more moderate decrease of triglycerides (21.3%), were observed. This lipid decrease was maximum at 1 year after biliopancreatic diversion. Important and persistent weight reduction that did not correlate with changes in lipids was observed. The youngest patients and those with high basal lipid levels proved to benefit most from biliopancreatic diversion gastric bypass. There were no important side-effects. Conclusion Biliopancreatic diversion bypass, with careful selection of patients, is a well tolerated procedure that offers excellent results in the short- and mid-term in reduction in weight and blood levels of most atherogenic lipoproteins.
