Endoscopic sclerotherapy with fibrin glue as compared with polidocanol to prevent early esophageal variceal rebleeding

Abstract Background/Aims: Endoscopic sclerotherapy is of proven benefit for patients after esophageal variceal bleeding, but is associated with substantial local and systemic complications. Since fibrin glue is a promising agent for endoscopic schlerotherapy of esophageal varices, we compared its safety and efficacy in patients after esophageal variceal bleeding. Patients and Methods: In a randomized, controlled trial, 36 patients with an acute episode on variceal bleeding were endoscopically treated with either polidocanol (18 patients) or fibrin glue (18 patients) by intravariceal injections within 12 h of admission. Tissue compatability, incidence of various complications, episodes of rebleeding and overall survival rates were investigated. Results: Rebleeding, especially from enrollment to day 28, was less common in the fibrin group ( p =0.046), and all patients treated with fibrin glue survived for more than 28 days, whereas five patients treated with polidocanol died within this period. The incidence of sclerotherapy-induced ulcers was significantly lower in the fibrin group than in the polidocanol group ( p =0.001), and major complications such as perforation or ulcer bleeding were observed only in the polidocanol group. There were no complications in any group due to activation of systemic coagulation, fibrinolysis or clinically relavant pulmonary embolization. Conclusions: We conclude that fibrin glue is an efficient and safe agent for endoscopic sclerotherapy of bleeding esophageal varices, especially in the immediate posthemorrhagic period.
