Abstract
BACKGROUND

The severity of nonalcoholic fatty liver disease (NAFLD) and lipid metabolism are related to the occurrence of colorectal polyps. Liver-controlled attenuation parameters (liver-CAPs) have been established to predict the prognosis of hepatic steatosis patients.

AIM

To explore the risk factors associated with colorectal polyps in patients with NAFLD by analyzing liver-CAPs and establishing a diagnostic model.

METHODS

Patients who were diagnosed with colorectal polyps in the Department of Gastroenterology of our hospital between June 2021 and April 2022 composed the case group, and those with no important abnormalities composed the control group. The area under the receiver operating characteristic curve was used to predict the diagnostic efficiency. Differences were considered statistically significant when P < 0.05.

RESULTS

The median triglyceride (TG) and liver-CAP in the case group were significantly greater than those in the control group (mmol/L, 1.74 vs 1.05; dB/m, 282 vs 254, P < 0.05). TG and liver-CAP were found to be independent risk factors for colorectal polyps, with ORs of 2.338 (95%CI: 1.154–4.733) and 1.019 (95%CI: 1.006–1.033), respectively (P < 0.05). And there was no difference in the diagnostic efficacy between liver-CAP and TG combined with liver-CAP (TG+CAP) (P > 0.05). When the liver-CAP was greater than 291 dB/m, colorectal polyps were more likely to occur.

CONCLUSION

The levels of TG and liver-CAP in patients with colorectal polyps are significantly greater than those patients without polyps. Liver-CAP alone can be used to diagnose NAFLD with colorectal polyps.

Core Tip: This study was designed to explore the risk factors associated with colorectal polyps in patients with nonalcoholic fatty liver disease (NAFLD) by analyzing liver-controlled attenuation parameters (liver-CAPs) and establishing a diagnostic model. We found that the triglyceride (TG) and liver-CAPs in patients with colorectal polyps were significantly greater than those in patients without colorectal polyps. When the liver-CAP was greater than 291 dB/m, colorectal polyps were more likely to occur. Additionally, no difference was observed in the diagnostic efficacy or specificity between liver-CAP and TG+CAP. Liver-CAP alone can also be used to diagnose NAFLD patients with colorectal polyps.
