Abstract:
Colonic disease is relatively uncommon in cirrhosis. To determine the prevalence of colonic lesions in cirrhosis of all types, cirrhotics evaluated for possible liver transplantation underwent combined pan upper endoscopy and colonoscopy. The patients were divided into two main groups, 248 with parenchymal liver disease (nonviral and viral) and 164 with cholestatic liver disease. The prevalence of the various colonic lesions identified was: polyps, 8.4%; nonspecific edema, 19.9%; inflammatory changes, 11.6%; hemorrhoids, 25.2%; and rectal varices, 3.6%. Normal findings were present in 42.4%. Except for an increased prevalence (P less than 0.05) of edema and a reduced prevalence (P less than 0.001) of inflammatory changes in the parenchymal liver disease group, the prevalence for all other lesions was similar in the two groups. Esophageal varices were present in most patients with hemorrhoids and in all with rectal varices. The degree of portal hypertension and/or disease severity was associated with hemorrhoids but not with rectal varices. The higher prevalence of inflammatory changes in the cholestatic group was because one fourth of this group had an inflammatory bowel disease.
