Objective: To compare the efficacy and safety of 12-24 hours versus 72 hours of intravenous terlipressin therapy in patients with acute esophageal variceal bleeding (AVB). Data sources: A systematic search was conducted using PubMed, Scopus, Cochrane Library, Google Scholar, Web of Science, VHL, and ClinicalTrials.gov for studies published up to February 24, 2024. The search terms included "terlipressin," "variceal bleeding," "short-course," and "72-hour treatment." Study selection and data extraction: Randomized controlled trials (RCTs) comparing 12 to 24 hours with 72 hours of terlipressin therapy in patients with AVB were included. Studies not meeting these criteria or focusing on unrelated outcomes were excluded. Two authors conducted data extraction and bias assessment independently, with discrepancies resolved by a third reviewer. Baseline characteristics and outcomes (rebleeding and mortality within 5 days) were recorded. Results: Four RCTs with 469 patients were included in the analysis. There were no significant differences observed in 5-day rebleeding rates (OR = 0.943; 95% CI [0.384, 2.317]; P = 0.898) or mortality rates (OR = 0.386; 95% CI [0.066, 2.260]; P = 0.291) between terlipressin treatment durations of 12 to 24 hours and 72 hours within the first 5 days posttreatment. In addition, no heterogeneity was found in both variables (P > 0.1). Conclusion: This meta-analysis indicates that there is no significant difference in rebleeding rates or mortality between 12 to 24 hours and 72 hours of terlipressin therapy for AVB within 5 days posttreatment. Shorter treatment durations may offer advantages in terms of resource utilization and adverse event risk but require further validation through studies involving larger patient populations.
