Background: Colonic mucosal lesions observed in patients with portal hypertension have been reported as portal hypertensive colopathy. We studied the rectal mucosa in patients with liver cirrhosis to evaluate the prevalence of mucosal reddening which looks like gastric red spots in the portal hypertensive gastropathy and to determine whether there is a correlation between this lesion and portal hypertension or the severity of liver disease. Methods: Seventy‐two patients with liver cirrhosis and 50 control subjects were examined. Colonoscopy was performed to evaluate the presence of mucosal reddening in the rectum. We investigated the relations between rectal mucosal reddening and esophageal varices, portal hypertensive gastropathy and the severity of liver cirrhosis. Results: Rectal mucosal reddening was observed in eight of 72 patients with liver cirrhosis but in none of the 50 control subjects; its prevalence in cirrhosis patients was significantly higher than that in the control subjects ( P < 0.05). Cirrhosis patients with esophageal varices were more likely to have rectal mucosal reddening than cirrhosis patients without esophageal varices ( P < 0.05). In addition, the occurrence of rectal mucosal reddening correlated with the severity of cirrhosis, based on Child–Pugh's classification ( P < 0.05). Conclusion: We have shown that rectal mucosal reddening develops in patients with liver cirrhosis and is associated with the existence of esophageal varices and the severity of liver cirrhosis. These results suggest the possibility that portal hypertension and impaired liver function may play an important role in the pathogenesis of rectal mucosal reddening in patients with cirrhosis.
