Background and Aims Umbilical hernia is a common abdominal complication in cirrhotic patients with ascites. Our study aimed to evaluate the correlation of umbilical hernia with the volume of ascites. Methods Cirrhotic patients that underwent axial abdominopelvic computed tomography (CT) scans at our hospital between June 2012 and June 2014 were eligible. All CT images were reviewed to confirm the presence of umbilical hernia. The volume of ascites was estimated by five‐point method. Results One hundred and fifty‐seven patients were enrolled into this study. Among them, 101 patients had ascites and 6 patients had umbilical hernia. Alkaline phosphatase (AKP) and serum sodium were significantly lower in patients with umbilical hernia (P = 0.008, P = 0.011, respectively). Child‐Pugh scores and the volume of ascites were significantly higher in patients with umbilical hernia (P = 0.03, P < 0.0001, respectively). Correlation analysis demonstrated that the volume of ascites, Child‐Pugh scores, and blood ammonia had positive correlations with umbilical hernia ( r = 0.4579, P < 0.0001; r = 0.175, P = 0.03; r = 0.342, P = 0.001, respectively) and that serum sodium had a negative correlation with umbilical hernia ( r = –0.203, P = 0.011). In patients with ascites ≥2000 mL, only AKP was significantly associated with umbilical hernia (P = 0.0497). No variables were significantly associated with umbilical hernia in a subgroup analysis of patients matched according to the volume of ascites. Conclusions The volume of ascites has a positive correlation with umbilical hernia. However, the factors associated with umbilical hernia in patients with severe ascites remain unclear.
