Background: The management of acute esophageal variceal bleeding remains a clinical challenge. Band ligation is the main therapeutic option, but it may be technically difficult to perform in active bleeders. This may necessitate an alternative therapy for this group of patients. This study was conducted to assess the safety and efficacy of sclerotherapy versus cyanoacrylate injection for management of actively bleeding esophageal varices in cirrhotic patients.
Methods: This prospective study included 113 cirrhotic patients with actively bleeding esophageal varices. They were randomly treated by endoscopic sclerotherapy or cyanoacrylate injection as banding was not suitable for those patients due to profuse bleeding making unclear endoscopic visual field. Primary outcome was incidence of active bleeding control and secondary outcomes were incidence of six weeks rebleeding, complications, and mortality among the studied patients.
Results: Initial bleeding control was significantly higher in cyanoacrylate versus sclerotherapy groups (98.25, 83.93% respectively, P = 0.007). No significant differences between sclerotherapy and cyanoacrylate groups regarding rebleeding (26.79, 19.30% respectively, P = 0.344), complications, hospital stay or mortality rate were observed.
Conclusions: Based on this single-center prospective study, both of these therapies appear to have relatively favorable outcomes, although cyanoacrylate injection may be superior to sclerotherapy for initial control of active bleeding.
