Esophageal collateral veins in predicting esophageal variceal recurrence and rebleeding after endoscopic treatment: a systematic review and meta-analysis

摘要

Endoscopic treatment is recommended for the management of esophageal varices. However, variceal recurrence or rebleeding is common after endoscopic variceal eradication. Our study aimed to systematically evaluate the prevalence of esophageal collateral veins (ECVs) and the association of ECVs with recurrence of esophageal varices or rebleeding from esophageal varices after endoscopic treatment.
