The aim of this study is to evaluate the effectiveness of non-shunting operation on IPH. 43 patients with IPH who underwent non-shunting operation were investigated. Evaluation of the operative results included: Childs classification, endoscopic findings, operative procedure, cumulative recurrence rate of varices, cumulative survival rate and cause of death.Results: 36 patients were operated by transthoracic esophageal transection, 3 patients by transabdominal esophageal transection and 4 patients by Hassab operation. 74.4% of the patients were classified to A, 20.9% to B and 4.7% to C. Degree of esophageal varices, 44.2% of the patients were regarded as LsF3 by Japanese criteria (Japanese Society of Portal Hypertension) at pre-operation, postoperatively these were disappeared or improved without RC sign. The cumulative recurrence rate of varices and bleeding after 15 years were 10.0% and 5.5%, showing lower rate than those of LC and EHO. The cumulative survival rates (15 years) of patients with IPH showed 63.9%, better than 32.1% in LC.Conclusion: For patients with IPH, transthoracic esophageal transection was considered to be a excellent procedure because of low recurrence rate of varices, bleeding and good survival rate.
