title: Portal hypertensive enteropathy.
abstract: The available data on the use of VCE in patients who have cirrhosis and portal hypertension are inadequate to reach a firm conclusion about the usefulness of this diagnostic tool in this patient population. In fact, only retrospective case series exist, in which the characteristics of the patients are heterogeneous in terms of severity of liver disease and of portal hypertension, etiology of cirrhosis, and indication for VCE. In addition, the controls included in the studies are heterogeneous or poorly described. In spite of this, it appears that in patients with portal hypertension, the small bowel frequently shows mucosal abnormalities. Such abnormalities appear to be particularly frequent in patients who have severe portal hypertension and in those with low hemoglobin levels. The clinical significance of these findings remains undefined, however, especially in view of the fact that small bowel lesions also have been found in about 10% of patients with arthritis not taking nonsteroidal anti-inflammatory drugs and in 13.8% of healthy subjects [41,42]. Therefore,large prospective studies are needed to evaluate the prevalence and clinical significance of small bowel mucosal changes in patients who have cirrhosis. Such studies should compare patients who have cirrhosis with healthy subjects. A comparison between cirrhotic patients with a history of intestinal bleeding and bleeding patients without cirrhosis also would be interesting.
