Comparison of Changes in Lipid Profile after Bilio-intestinal Bypass and Gastric Banding in Patients with Morbid Obesity

Abstract

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.

Changes in lipid profile and insulin resistance in obese patients after Scopinaro biliopancreatic diversion

“…These levels did not increase until the sixth month PS, but this increase did not become significant. Contrary to the other groups [14,37], HDL-c values in non-DM were all over 35 mg/dL at the end of the study, except 7% of patients that show PS HDL-c levels lower than reference values (35 mg/ dL). Our results agree with the meta-analysis of Buchwald et al [42], in which they observed a significant decrease in TC, LDL-c, and TG, but there was no significant increase in HDL-c.…”

A rat model of childhood diet-induced obesity: Roux-en-Y gastric bypass induced changes in metabolic parameters and gastric peptide ghrelin

“…These improvements are part of the many beneficial effects of weight loss, and RYGB induced weight loss in particular. The decrease in HDL in our study, although not a beneficial effect of RYGB, has been reported in human studies in the early post-operative state with increases later in recovery [11,12]. Interestingly, the metabolic parameters in SH rats were not significantly different from SC and RYGB-operated rats at time of sacrifice.…”

Exploring the impact of bariatric surgery on high density lipoprotein

“…In 2 comparative studies with follow-up times up to 3 years, the levels of HDL after bilio-intestinal bypass were lower than the preoperative values. Conversely, the control group that underwent AGB had a significant rise in HDL [77,78].…”
