Microwave coagulation versus sclerotherapy after band ligation to prevent recurrence of high risk of bleeding esophageal varices in Child-Pugh’s A and B patients

摘要

Background The combination of endoscopic band ligation (EBL) with either endoscopic injection sclerotherapy (EIS) or thermal therapy has been shown to reduce recurrence of esophageal varices compared to EBL alone. The aim of this prospective trial was twofold: 1) to evaluate the safety and efficacy of EBL used in association with microwave coagulation (MC), a thermal endoscopic therapy method, for treating esophageal varices and preventing recurrence; and 2) to compare these results to the joint application of EBL and EIS.
