Gallstones associated with nonalcoholic steatohepatitis (NASH) and metabolic syndrome

Background/aims: We aimed to evaluate the prevalence of non-alcoholic steatohepatitis and metabolic syndrome in patients with symptomatic gallstones undergoing laparoscopic or open cholecystectomy. Methods: A study of 95 patients was performed. Simultaneous liver biopsies were taken during cholecystectomy between 2006 and 2007. There were no postoperative complications. Patients with significant alcohol intake, hepatitis B or C (virus-positive), autoimmune diseases, and Wilson's disease were excluded. Demographics, liver function tests, lipid profile, and ultrasound findings of patients with and without non-alcoholic steatohepatitis were compared. Results: A total of 95 patients completed the study. The mean age was 52.15 years, and 29 patients were male and 66 female. Fifty-two patients (55%) had biopsies compatible with non-alcoholic steatohepatitis. Conclusions: Fifty-five percent of patients with gallbladder stones had associated non-alcoholic steatohepatitis. Awareness of this association may result in an earlier diagnosis. The high prevalence of non-alcoholic steatohepatitis in patients with galbladder stone may justify routine liver biopsy during cholecystectomy to establish the diagnosis and stage and possibly direct therapy.
