Cyanoacrylate is well recognized for its effect in the treatment of the gastric variceal bleeding rather than the esopahgeal variceal bleeding. We used endoscopic injection sclerotherapy (EIS) with cyanoacrylate for the control of esophageal variceal bleeding in which endoscopic variceal ligation (EVL) was difficult due to severe post-EVL scar changes of the esophageal mucosa. The hemostasis by EIS with cyanoacrylate was successfully achieved despite the massive bleeding. However, esophageal obstruction occurred after the EIS treatment. Later, the obstruction resolved spontaneously as the polymer was expelled into the esophageal lumen. We report this case with a brief review of the literatures.
