Abstract
The endoscopic variceal sclerosis (EVS) was employed in 24 patients with esophageal varices. In 15 patients, ethanolamine oleate was injected intravariceally (EAO, emergent : 2, elective : 4, prophylactic : 9). On the other hand, polidocanol was injected extra or intravariceally in another 9 patients (emergent : 0, elective : 4, prophylactic : 5). The effects and complications were compared between these two methods. 1. The mean number of times that sclerotherapy was performed for apparent decreasement of varices and red color sign were 1.5 times with EAO and 2.3 times with polidocanol. Therefore, the intravariceal injection with EAO was much more effective than that with polidocanol. 2. The complications were seen more often in the EVS using EAO than using polidocanol. 3. EAO should be injected intravenouslly by fluoloscopy because extravariceal injection of EAO formed large ulcer. Therefore, EVS using EAO is more complicated than that using polidocanol.
