Clinical relevance of colonic lesions in cirrhotic patients with portal hypertension.
OBJECTIVE
This prospective study was conducted in order to evaluate whether the colonic lesions previously described in cirrhotic patients may be of clinical relevance.


METHODS
Eighty-five patients with cirrhosis of the liver, but without colonic or systemic diseases unrelated to the liver disease, underwent colonoscopy and were followed up for at least 2 years.


RESULTS
Colonic varices were observed in 31 % of the patients, portal hypertensive colopathy (PHC; defined as diffuse hyperemia, edema, spider angiomas, and spontaneous bleeding of the colonic mucosa) in 54 %, and normal colonic findings in 18 %. Colonic varices and PHC were present simultaneously in 27 % of the patients. Previous sclerotherapy or band ligation treatment for esophageal varices had been carried out in 27 % and 23 % of the patients, respectively. Portal hypertensive gastropathy was observed in 42 % of the patients. Polyps were found in 12 % of the cirrhotic patients and cancer in 3 %. All of the patients were followed up for at least 2 years; 34 % of them developed upper gastrointestinal hemorrhage (81 % from esophageal varices, 19 % from the stomach), while only 6 % developed lower gastrointestinal bleeding.


CONCLUSIONS
Colonic lesions are frequent in cirrhotic patients, but statistical analysis showed that these lesions are not specific for the disease and do not correlate with the etiology and degree of cirrhosis, with the endoscopic treatment of esophageal varices, or with the risk of bleeding from the lower gastrointestinal tract.
