| Summary: | Esophageal varices are expanded veins of the submucosa that develop in patients with portal hypertension. They develop as collaterals between the portal vein and the superior vena cava. Varices are seen when the HPVG rises >12mmHG and can lead to a life-threatening bleeding episode. Endoscopic band ligation (EBL) is the treatment of choice of acute variceal bleeding. It is also performed for primary and secondary prophylaxis of bleeding from esophageal varices. After EBL, patients are at risk of postinterventional bleeding. Therefore, patients are often hospitalized until endoscopy proves all applied ligation bands have dropped off. At present, there is no standardized algorithm for surveillance of patients after EBL. Furthermore, risk factors for bleeding complications after EBL are poorly evaluated. The available studies mostly investigated patient collectives .after endoscopic sclerotherapy. The aim of this study was to investigate bleeding behaviour after EBL, to make recommendations for in- and out-patient surveillance after EBL and to analyze independent risk factors for bleeding complications after EBL. |
