Efficacy of vasopressin/terlipressin and somatostatin/octreotide for the prevention of early variceal rebleeding after the initial control of bleeding: a systematic review and meta-analysis

摘要

PurposeOur purpose was to conduct a meta-analysis to compare the effectiveness of vasopressin/terlipressin and somatostatin/octreotide on variceal re-bleeding within and after 5?days of initial control bleeding.MethodsA search was conducted of PubMed, the Cochrane database, and Google Scholar until June 31, 2014 using combinations of the search terms: esophageal varices, variceal re-bleeding, recurrent variceal hemorrhage, early re-bleeding, vasopressin, somatostatin, terlipressin, octreotide. Inclusion criteria were: (1) randomized controlled trials, (2) patients with esophageal or esophageal and gastric varices confirmed by endoscopy, (3) re-bleeding control was evaluated, (4) treatment with somatostatin/vasopressin. Outcome measures were the re-bleeding rates within 5?days (≤5?days) or after 5?days (>5?days) after initial treatment.ResultsSix studies were included in the analysis. Five studies had complete data of re-bleeding rate within 5?days after initial treatment, and the combined odds ratio (OR) of 0.87 [95?% confidence interval (CI) 0.51, 1.50] indicated that there was no difference in the re-bleeding rate between patients treated with vasopressin/terlipressin or somatostatin/octreotide. Two studies had complete data of the re-bleeding rate 5?days after initial treatment, and the combined OR of 1.12 (95?% CI 0.64, 1.95) indicated there was no difference in the re-bleeding rate between patients who were treated with vasopressin/terlipressin or somatostatin/octreotide.ConclusionThere is no difference between vasopressin/terlipressin and somatostatin/octreotide in prevention of re-bleeding after the initial treatment of bleeding esophageal varices.
