Present status of sclerotherapy and surgical treatment for esophageal varices in Japan. Japanese Research Society for Portal Hypertension and Japanese Research Society for Sclerotherapy of Esophageal Varices.
A nationwide survey on the treatment for esophageal varices was performed in 1990 jointly by the Japanese Research Society for Portal Hypertension and the Japanese Research Society for Sclerotherapy of Esophageal Varices to clarify the present status and strategy of this treatment in Japan. A total of 12,675 cases, including 4,159 cases of nonshunting procedures and 7,612 cases of sclerotherapy, were collected from 101 institutions. The number of patients had greatly increased in the first half of the 1980s. With regard to the therapeutic strategy, surgical procedures were not recommended in either emergency or prophylactic cases in terms of the timing of the operation, or in Child C cases in terms of the degree of hepatic insufficiency. Endoscopic injection sclerotherapy became the leading method of treatment and in 1988 only 16% of 1,528 cases were treated by surgical procedures. The strategy for the same group of patients differed between medical and surgical institutions. With regard to sclerotherapy, repeated intravariceal injection and combined intra- and paravariceal injection were the two main techniques and 10-year cumulative survival rates were 62.8% in Child A cases, 47.7% in Child B cases, and 13.2% in Child C cases. With regard to surgical procedures, 10-year survival rates were 50.6% in esophageal transection, 42.5% in gastric transection, 53.1% in cardiectomy, and 43.0% in selective shunt procedures. We are quite convinced that this report will prove useful in determining the future strategy for treating esophageal varices.
