Injection sclerotherapy for gastric varices using N-butyl-2-cyanoacrylate and ethanolamine oleate



Injection sclerotherapy for gastric varices using N-butyl-2-cyanoacrylate and ethanolamine oleate



Hepato-Gastroenterology 45(22): 1155-1158



BACKGROUND/AIMS: Tissue adhesive agents, such as the cyanoacrylates, have been used as an alternative to conventional sclerotherapy to treat gastric varices, but the long-term efficacy of this approach has not been determined. We evaluated the efficacy and long-term outcome of injection sclerotherapy with n-butyl-2-cyanoacrylate and ethanolamine oleate in 16 patients with gastric varices. METHODOLOGY: We evaluated the effect of injection sclerotherapy in 16 Japanese patients with gastric varices. Injection sclerotherapy was performed on an emergency basis in 6 patients, an elective basis in 5 patients, and as prophylaxis in 5 patients. RESULTS: No bleeding was observed in the 7 patients in whom gastric varices disappeared during the 51 month follow-up period. The non-bleeding rate after treatment was significantly higher in this group than in the 9 patients in whom gastric varices did not disappear (p<0.05). Acute bleeding was stopped in 5 (83.3%) of 6 patients. The single failure was a patient in whom the sclerosant could not be injected into the gastric varices. No serious complications, such as emboli in other organs, were observed. CONCLUSION: The results suggest that this therapy is A safe and useful treatment for gastric varices and that the goal of injection sclerotherapy should be the disappearance of gastric varices.
