ABSTRACT
The incidence of peptic ulcer is increased in cirrhosis and is widely believed to be even greater in cirrhotic patients with portacaval anastomosis (PCA). Two prospective, controlled investigations of prophylactic PCA were evaluated to compare the frequency of peptic ulcer in two groups of cirrhotic patients with similar clinical and laboratory manifestations of cirrhosis randomly selected to be an unoperated Control Group (60 patients) or to have PCA (Shunt Group, 48 patients). In addition, nonrandomized groups of cirrhotic patients, 77 of whom were excluded from the randomized study and 44 of whom had therapeutic PCA, were studied. A diagnosis of chronic peptic ulcer was based on the demonstration of an ulcer crater by X-ray, endoscopy, surgery, or autopsy. Prior to inclusion in these studies, approximately 10% of patients had had peptic ulcer. After inclusion, during a mean follow-up period of 45 months, 12% of both the Control and Shunt Groups developed peptic ulcers. The frequency of complications of peptic ulcer, of recurrence of peptic ulcer, or of acute or symptomatic (unproved) ulcer were similar in both groups. Ulcers tended to develop later in shunted than in unshunted patients. Similar data were obtained from three of four other controlled investigations of PCA. This investigation does not find an increased occurrence of peptic ulcer after PCA. The frequency of ulcer in cirrhosis appears to increase with the duration of the disease independent of the presence or absence of PCA.
