Core Tip
Core tip: We performed a meta-analysis to evaluate risk ratio and 95% confidence interval (CI) of combined studies for the treatment of patients with esophageal variceal bleeding between endoscopic variceal ligation (EVL) and endoscopic injection sclerotherapy (EIS). Our meta-analysis has found that EVL is better than EIS in terms of the lower rates of rebleeding, complications, and the higher rate of variceal eradication. Therefore, EVL is the first choice for esophageal variceal bleeding.
