[Prevention of recurrent hemorrhage in patients with cirrhosis. Results of a controlled trial of propranolol versus endoscopic sclerotherapy].

Between July 1984 and March 1986, we conducted a prospective randomized trial comparing propranolol and endoscopic sclerotherapy in the prevention of recurrent variceal hemorrhage in a group of non selected alcoholic cirrhotics. Seventy-six patients with variceal hemorrhage were randomized to receive propranolol (P) (34 patients), or sclerotherapy (S) (42 patients) approximately 12 days after initial bleeding. The 2 groups were similar as concern age, sex, etiology of cirrhosis, severity of liver failure, the number of previous hemorrhages, and the severity of initial hemorrhage.

Rioprostil vs. ranitidine in duodenal ulcer healing: a double-blind multicentre trial.

A total of 156 patients with endoscopically proven duodenal ulcers are randomized in a double-blind, multicentre trial comparing rioprostil, 300 micrograms b.d., with ranitidine, 150 mg b.

Rioprostil and ranitidine in the prevention of duodenal ulcer relapse.

One hundred and ninety duodenal ulcer patients who had relief of pain and endoscopically proven ulcer healing after a short treatment period are allocated at random to double-blind maintenance treatment with a synthetic dehydroprostaglandin-E1, rioprostil, 300 micrograms, or ranitidine, 150 mg, at bedtime for 6 months. Patients are monitored every two months and examined by endoscopy after six months of treatment, or more often if warranted. The cumulative relapse rate in the rioprostil group at six months is 32% (25/78) vs.
