Abstract
BACKGROUND: Hyperplastic polyps (HPs) of the colon are the most common colorectal polyps. Metabolic syndrome components such as obesity and hyperlipidemia are considered the most common etiological factors for HPs as well contributing to the pathogenesis of fatty liver disease. OBJECTIVES: To determine the possible association between biopsy-proven steatohepatitis and hyperplastic colonic polyps. METHODS: This retrospective cohort observational study conducted at the Holy Family Hospital in Nazareth, Israel, included subjects who underwent screening colonoscopy over a 2 year period. Data were extracted from the patient charts and included demographics, anthropometric measurements, vital signs, underlying diseases, medical therapy, laboratory data, and results of the liver biopsy. The colonoscopy report and pathological report of each extracted polyp were also evaluated. RESULTS: A total of 223 patients were included in the study: 123 patients with biopsy-proven non-alcoholic steatohepatitis (NASH) and 100 patients without NASH who served as the control. Fourteen colonic adenomas (11% of patients) were found in the NASH group vs. 16 (16%) in the control group (P = 0.9); 28 HPs were found in the NASH group (22.7%) vs. 8 in the control group (8%) (P < 0.05). The multivariate analysis, after adjusting for, age, C-reactive protein and smoking, showed that the presence of NASH (OR 1.69, 95%CI 1.36-1.98, P < 0.01) was associated with increased risk for HP. CONCLUSIONS: Our study found an association between biopsy-proven steatohepatitis and the burden of hyperplastic polyp.
