Background: Strongly associated with obesity, non-alcoholic fatty liver disease is considered the hepatic manifestation of the metabolic syndrome. It presents as simple steatosis and steatohepatitis, which can progress to cirrhosis and its complications. Among the therapeutic alternatives is bariatric surgery. Aim: To compare the effect of the two most frequent bariatric procedures (sleeve and bypass) on liver disease regarding to epidemiological, demographic, clinical and laboratory parameters. Methods: The results of intraoperative and 12 months after surgery liver biopsies were used. The NAFLD activity score (NAS) was used to assess and compare the stages of liver disease. Results: Sixteen (66.7%) patients underwent Bypass procedure and eight (33.3%) Sleeve. It was observed that the variation in the NAFLD activity score was significantly greater in the Bypass group than in Sleeve (p=0.028) and there was a trend regarding the variation in fibrosis (p=0.054). Conclusion: Both surgical techniques were effective in improving the hepatic histology of most operated patients. When comparing sleeve and bypass groups, bypass showed better results, according to the NAS score.
On the present study, the prevalence of heavy use of alcohol was high and associated with a poorer prognosis in hospitalized cirrhotic patients, increasing the risk of infection and death.
Univentricular heart, also known as functionally single ventricle, is a complex group of heterogenous congenital heart defects, comprising multiple pathological subtypes. This may occur either with ventricular hypoplasia, double-inlet atrioventricular connections, or mitral or tricuspid valve atresia. Surgical correction is represented by the Fontan procedure, which is used to bypass the ventricular mass. When unsuccessful, cardiac transplant is an alternative. 1Previous studies have shown that obesity is associated with symptomatic heart failure and mortality in patients with Fontan palliation. 2 The prevalence of overweight and obesity increases with the age of patients undergoing Fontan conversion, with
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
