Long‐term observation in patients with esophageal varices after endoscopic variceal ligation accompanied with 24‐hour pH monitoring

Esophageal variceal ligation (EVL) is usually carried out to decrease the risk of hemorrhage. Several complications have been reported with the procedure, including bleeding from ligation‐induced esophageal ulcers or heartburn. However, there is scant evidence for gastroesophageal reflux caused by EVL. The aim of this study was to assess 24‐h pH monitoring in the esophagogastric junction before and after EVL and the bleeding rate for 18 months.
