One hundred and fifteen cases of endoscopically proven esophageal varices were treated with EIS involving 375 sessions at Taipei Municipal Jen-Ai Hospital from September 1983 to June 1986. The patients were treated with 5% ethanolamine oleate 6-8 ml (30 cases) or 2% sodium tetradecyl sulfate 2 ml (85 cases) in each varix. The technique we employed was the Takase's modified intravascular injection method.
