Prevention of Recurrent Bleeding in Cirrhotics with Recent Variceal Hemorrhage: Prospective, Randomized Comparison of Propranolol and Sclerotherapy

To compare the efficacy of endoscopic paravariceal sclerotherapy and oral propranolol in the prevention of recurrent upper gastrointestinal bleeding, 78 cirrhotic patients were randomly assigned to either treatment after an endoscopically proven bleed from esophageal varices. After randomization, but before treatment had been started, a total of eight patients had to be withdrawn from the study due to early rebleeding (requiring emergency sclerotherapy) or violations of the protocol. Among the 70 patients analyzed (36 sclerotherapy, 34 propranolol), both treatment groups were comparable with respect to demographic, clinical and laboratory data. The groups also did not differ with respect to continued alcohol intake. Sclerotherapy was performed twice weekly using 1% polidocanol as the sclerosing agent until the varices were eradicated or well-covered by fibrous tissue. Propranolol was given twice daily at a dose reducing the resting heart rate by 25% (60 to 320 mg per day; mean +/- SD = 161 +/- 80 mg per day). Patients were followed for up to 2 years with visits at 3 monthly intervals (mean follow-up = sclerotherapy, 14 months; propranolol, 9.2 months). Life table analysis of patients without rebleeding from nonvariceal sites revealed a tendency in favor of propranolol; however, the difference did not reach statistical significance. No significant difference was observed between sclerotherapy and propranolol in the proportion of patients rebleeding from esophageal varices or from all sources of upper gastrointestinal bleeding. Furthermore, survival was similar in both treatment groups.(ABSTRACT TRUNCATED AT 250 WORDS)
