摘      要：Background:Endoscopic treatment is recommended for the management of esophageal ***,variceal recurrence or rebleeding is common after endoscopic variceal *** 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 ***:We searched the relevant literature through the PubMed,EMBASE,and Cochrane Library *** of paraesophageal veins(para-EVs),periesophageal veins(peri-EVs),and perforating veins(PVs)were *** ratio(RR)and odds ratio(OR)with 95%confidence intervals(CIs)were calculated for cohort studies and case-control studies,respectively.A random-effects model was *** among studies was ***:Among the 532 retrieved papers,28 were *** pooled prevalence of para-EVs,peri-EVs,and PVs in patients with esophageal varices was 73%,88%,and 54%,*** pooled prevalence of para-EVs and PVs in patients with recurrence of esophageal varices was 87%and 62%,*** risk for recurrence of esophageal varices was significantly increased in patients with PVs(OR=9.79,95%CI:1.95-49.22,P=0.006 for eight case-control studies),but not in those with para-EVs(OR=4.26,95%CI:0.38-38.35,P=0.24 for four case-control studies;RR=1.81,95%CI:0.83-3.97,P=0.14 for three cohort studies).Patients with para-EVs had a significantly higher incidence of rebleeding from esophageal varices(RR=13.00,95%CI:2.43-69.56,P=0.003 for two cohort studies).Statistically significant heterogeneity was notable across the ***:ECVs are common in patients with esophageal *** of ECVs could be helpful for predicting the recurrence of esophageal varices or rebleeding from esophageal varices after endoscopic treatment.
