Abstract

Objective. Variceal recurrence following endoscopic band ligation (EBL) is common. Esophageal collateral veins (ECV) are observed by endoscopic ultrasound (EUS) in patients with portal hypertension. The aim of the present study was to assess the role of EUS in predicting the recurrence of esophageal varices following EBL. Material and methods. Forty patients who had undergone EBL for eradication of varices were examined over a 12-month period to detect variceal recurrence. EUS was performed before ligation to detect and describe the type, grade, and the number of ECV. EUS findings obtained prior to EBL were compared in the variceal recurrence and non-recurrence groups. Results. Of the 40 patients, 19 (47.5%) had variceal recurrence within 12 months of EBL. Univariate logistic regression analysis showed that severe peri-ECV (p < 0.001), multiple peri-ECV (p < 0.001), and the presence of perforating veins (p < 0.014) were statistically significantly related to the variceal recurrence after EBL. Multivariate logistic regression model found that only severe peri-ECV (odds ratio [OR] = 24.39; 95% confidence interval [CI]: 2.34–253.78) and multiple peri-ECV (OR = 24.39; 95% CI: 2.34–253.78) remained as independent prognostic factors for variceal recurrence. The sensitivity and specificity of multivariate logistic regression model in predicting variceal recurrence was 89.2% and 90.5%, respectively (prognostic value (AUC) = 0.946). Conclusion.Recurrence rate of esophageal varices after EBL is high (47.5%). EUS can clearly depict ECV and has a value in predicting variceal recurrence after EBL; severe peri-ECV and multiple peri-ECV were significant and independent prognostic factors associated with variceal recurrence risk.
