[Fiberendoscopic sclerotherapy of esophageal varices: relationship of varices size, quantity of sclerosing agent used and number of sessions].

By means of fiberendoscopic injection sclerotherapy, it was possible to achieve eradication of esophageal varices in 18 patients. At the onset of treatment 9 patients had small varices (grade II) and other 9 had big varices (grade III). It was found in the big varices group there was needed more courses (p less than 0.01) and a greater amount of sclerosing agent (p less than 0.001) than in the group with small varices. Since those patients with big varices required more courses and more volume of sclerosing agent, and in fact they have more risk to rebleed during the pre-eradication period. It is proposed as a solution during this period, the use of a B receptor blocking agent (Propranolol) simultaneously with sclerotherapy.
