Immediate endoscopic injection therapy of bleeding oesophageal varices: a prospective comparative evaluation of injecting materials in Egyptian patients with portal hypertension.
The present study was conducted to compare usual sclerosants: polidocanol 1%, ethanolamine oleate 5% and the tissue adhesive: cyanoacrylate in the control of oesophageal variceal bleeding in Egyptian patients with portal hypertension in a prospective comparative trial. Sixty patients with portal hypertension due to schistosomal hepatic fibrosis and/or posthepatitic liver cirrhosis who had presented with acute oesophageal variceal bleeding were enrolled. Patients received balloon tamponade prior to injection were excluded. Resuscitation had been done before or during emergency endoscopy. Emergency endoscopy was conducted within 2 hours from the onset of hematemesis. Patients were immediately randomized during emergency endoscopy to receive polidocanol 1%, ethanolamine oleate 5% or tissue adhesive. Variceal rebleeding was managed by reinjection. The three groups were comparable for age, sex, etiology of portal hypertension, Child-Pugh class and findings at emergency endoscopy. No active bleeding was observed at the end of all injection sessions. Rebleeding had been occurred within the first 24 hours in 2 (10%) patients in polidocanol group and 3 (15%) patients in ethanolamine group (P > 0.05). Reinjection did control rebleeding in 2 (10%) patients in ethanolamine group with a total success rate of 95%. Exsanguinating rebleeding occurred in 2 (10%) patients in polidocanol group and one (5%) patient in ethanolamine group (P > 0.05). Postinjection large ulcers were diagnosed either in polidocanol (15%) or ethanolamine (10%) groups (P > 0.05). Other complications were minor and showed no significant differences between the three groups. In coclusion, polidocanol, ethanolamine and cyanoacrylate are equally safe and effective. For immediate endoscopic injection therapy an experienced team must be available.
