Abstrakt: Background: The presence of hypercholesterolemia is currently not considered a selection criteria for performing gastric restrictive or diversionary bariatric surgery. Methods: We prospectively investigated the effects of the bilio-intestinal bypass (BI-bypass) with a wide cholecysto-jejunal anastomosis and of adjustable gastric banding (AGB) on blood lipid concentrations in obese patients. To clarify the mechanism of the hypocholesterolemic effect of the BI-bypass, daily fecal sterol excretion was measured by gas-liquid chromatography (GLC). Results: At 1 year after BI-bypass compared to baseline, the hypercholesterolemic (n=18) and the normocholesterolemic (n=19) patients significantly reduced total (−38% and −27%, respectively), LDL (−47% and −24%, respectively) and HDL (−11% and −13%, respectively) cholesterol and total / HDL cholesterol ratio (−25% and −13%, respectively). At 1 year after AGB, the total / HDL cholesterol ratio was significantly decreased (−11%) compared to baseline in hypercholesterolemic (n=12) but not in normocholesterolemic (n=6) patients, while total and LDL cholesterol were not affected in both groups. At 3 years after BI-bypass compared to baseline, the hypercholesterolemic (n=9) and the normocholesterolemic (n=11) patients significantly reduced total (−43% and −28%, respectively) and LDL (−53% and −29%, respectively) cholesterol and total / HDL cholesterol ratio (−38% and −21%, respectively). The BI-bypass induced a significant ( P <0.005; n=7) 6-fold increase in mean fecal cholesterol output. Conclusions: The BI-bypass but not the AGB leads to a persistent and marked beneficial effect on blood LDL cholesterol associated with an increased cholesterol fecal output. BI-bypass but not AGB is indicated in morbidly obese patients with hypercholesterolemia. [ABSTRACT FROM AUTHOR]
