title: Ethanolamine oleate is superior to polidocanol (aethoxysklerol) for endoscopic injection sclerotherapy of esophageal varices: a prospective randomized trial.
abstract: Thirty-four consecutive patients with liver cirrhosis and esophageal varices were included in a prospective randomized trial done to investigate the efficacy and safety of two sclerosants 5% ethanolamine oleate (EO) and polidocanol (1% Aethoxysklerol [AS]) for use in endoscopic injection sclerotherapy (EIS). Eighteen patients were randomly allocated to the group given EO and 16 to the AS group. These two groups were comparable with regard to age, sex, etiology and severity of the liver disease. The bleeding rate from esophageal ulcers which developed during the course of repeated EIS was significantly (P less than 0.05) higher in the AS group (31.3%, 5/16) than in the EO group (0%, 0/18). In 4 occasions bleeding from the esophageal ulcer could not be controlled with AS. In 3 of these 4 bleeding episodes, EO successfully halted bleeding from esophageal ulcer. In the other patient, a Sengstaken-Blakemore tube was inserted to stop the hemorrhage. The period and number of sessions of EIS for eradication of esophageal varices were significantly (P less than 0.05) shorter in the EO group than the AS group (EO: 4.0 +/- 0.8 [means +/- SD] sessions during 4.7 +/- 1.5 weeks versus AS: 4.8 +/- 1.2 sessions during 5.4 +/- 1.6 weeks). The rate of early mortality did not differ between the two groups. We conclude that 5% ethanolamine oleate seems to be superior to 1% Aethoxysklerol when used for sclerosing esophageal varices.
