Resumen

Background: Gastroesophageal variceal bleeding is a common complication of portal hypertension. Current guidelines recommend b-blockers for primary prophylaxis. However, evidence suggests that endoscopic variceal ligation (EVL) reduce bleeding episodes. Aims: To compare endoscopic EVL with propranolol (PPL) for primary prophylaxis of variceal bleeding. Methods: We conducted a randomized controlled trial. Over a 9-year period, 75 patients with cirrhosis and high-risk esophageal varices (HREV) were recruited and allocated to EVL (n = 39) or PPL (n = 36). Primary outcome was variceal bleeding. Secondary outcomes were survival, source of bleeding and serious adverse events. Analyses were made by intention-to-treat. Results: Baseline characteristics were similar. Medium follow-up was 1647 ± 1096 days. Complete follow-up was achieved in 85% of patients. Variceal bleeding occurred in 12% of EVL and in 25% of PPL group (p = 0.17). The actuarial risks of bleeding after 2 years were similar in both groups. Overall mortality was 51% in EVL and 33% in PPL group (p = 0.17). Patients in the EVL group showed a lower rate of esophageal variceal bleeding (5.1% v/s 25%, p=0.027) and a higher rate of subcardial variceal bleeding compared with PPL group (7.7% v/s 0%, p = 0.027). Serious adverse events related to EVL occurred in 2 patients, including 1 death. Conclusions: The present study supports that PPL should be considered the first choice in primary prophylaxis of variceal bleeding offering similar effects and lower severe adverse events compared with EVL.
