Abstract

Non‑alcoholic fatty liver disease (NAFLD) and colorectal polyps have been shown to have similar pathogenic factors. The understanding of the association between these two pathologies may contribute to the early diagnosis and treatment of colorectal tumors. The present study compared the biological characteristics of colorectal polyps between patients with and without NAFLD. For this purpose, 1,538 patients with colorectal polyps treated from July, 2013 and June, 2020 were included and divided into the NAFLD and control group (non‑NAFLD group). The location, number, morphology, size and pathology of the polyps were compared between the 2 groups. For the analysis of the biological characteristics of the polyps, the multiple of number (74.5%), percentages of polyps >1.0 cm in diameter (62%) and polyps with advanced adenomas. For the analysis of the biological characteristics of the polyps, the multiple of number (74.5%), percentages of polyps in diameter of 1.0 to <2.0 cm + ≥2.0 cm (48.4 and 13.6%, respectively) and polyps with advanced adenomas (62.9%) in the NAFLD group exhibited significant differences compared with the control group (69.5, 39.2, 6.3 and 55.3%, respectively; all P<0.05); however, no significant differences were observed in the location and morphology of the colorectal polyps between the patients with NAFLD and the controls (P>0.05). When the patients were stratified by sex, age and body mass index, it was found that the patients in the NAFLD group with a polyp size <1.0 cm and those with advanced adenomas exhibited significant differences compared with the control group (P<0.05, respectively). Further analysis revealed that the classification percentage of advanced adenomas in the NAFLD group only exhibited a statistically significant difference compared with the control group in patients with a lower weight (P<0.05). On the whole, the present study demonstrates that NAFLD is significantly associated with the presence of colorectal polyps, particularly in patients with multiple polyps, those with a large size and with villous features (advanced adenomas). Patients with NAFLD may thus be considered a target group for screening colonoscopy.
