Abstract
Background: Endoscopic variceal ligation is one of methods used as a prophylaxis or as a treatment in patients with active bleeding. One of the complications of endoscopic variceal ligation is ulcer developed at site of band with prevalence reported in few reports to be 3.6%-15% which can cause fatal bleeding. There are only limited reports of this serious complication, and the risk factors and the treatment methods are not well established. Aim of this study: Assessment of the prevalence and risk factors of post EVL-inducedulcer in cirrhotic patients undergone endoscopic variceal band ligation. Methods: Cross-sectional study included 200 cirrhotic patients for whom endoscopic variceal band ligation is indicated either for prophylaxis or for treatment of acute variceal bleeding at Kasr-Alaini university hospital, Internal Medicine department, Alebrashi endoscopy unit throughout period from April 2018 to April 2019. The patients were classified into 2 groups. group 1: included 100 patients undergoing prophylactic endoscopic variceal band ligation. group 2: included 100 patients undergoing endoscopic band ligation for treatment for active variceal bleeding. We needed to assess the prevalence and risk factors of post EVL-induced ulcer in cirrhotic patients undergone endoscopic variceal band ligation through follow up endoscopy that was done 14-21 days post banding. All patients undergone clinical and laboratory assessment to identify the risk factors for EVL-induced ulcer
