RESUMO
BACKGROUND & AIMS: Rebleeding after an initial oesophageal variceal haemorrhage remains a significant problem despite therapy with band ligation, non-selective ß-blockers or a combination of these. Carvedilol is a vasodilating non-selective ß-blocker with alpha-1 receptor and calcium channel antagonism. A recent study has suggested it is effective in the prevention of a first variceal bleed. Our aim was to compare oral carvedilol with variceal band ligation (VBL) in the prevention of rebleeding following a first variceal bleed. METHODS: Patients who were stable 5 days after presentation with a first oesophageal variceal haemorrhage and had not been taking ß-blockers were randomised to oral carvedilol or VBL. Patients were followed-up after one week, monthly, then every 3 months. The primary end point was variceal rebleeding on intention-to-treat analysis. RESULTS: 64 patients were randomised, 33 to carvedilol and 31 to VBL. 58 (90.6%) patients had alcohol related liver disease. Age and Child-Pugh score were similar in both groups at baseline. Median follow-up was 26.3 (interquartile range [IQR] 10.2-46.6)months. Compliance was 68% and 65% for carvedilol and VBL respectively (p=0.993) and serious adverse events between the two groups were similar (p=0.968). Variceal rebleeding occurred during follow-up in 12 (36.4%) and 11 (35.5%) patients in the carvedilol and VBL groups, respectively (p=0.857), with 9 (27.3%) and 16 (51.6%) deaths in each group, respectively (p=0.110). CONCLUSIONS: Carvedilol is not superior to VBL in the prevention of variceal rebleeding. The trend to a survival benefit for patients taking this drug compared with those undergoing banding requires further exploration.
