Earlier recurrence of esophageal varices, following therapy, in patients with primary biliary cirrhosis (PBC) compared with non-PBC patients

摘要

Background. Variceal bleeding is a common, life-threatening complication of primary biliary cirrhosis (PBC). Recently, several reports have suggested that the existence of esophageal varices in patients with PBC is a significant factor in the assessment of disease prognosis. However, there have been no reports on the recurrence of esophageal varices following treatment in patients with PBC. In this study, we investigated the recurrence of esophageal varices in PBC patients and attempted to identify predictive factors for the recurrence of esophageal varices. Methods. Between April 1993 and August 2003, 138 patients with esophageal varices who had been treated by endoscopic variceal ligation (EVL; 96 men and 42 women; age, 33-83 years; mean, 62.6 +/- 10.1 years), were enrolled in the present study. The diagnosis of esophageal varices was made by upper gastrointestinal endoscopy, and the varices were graded according to the criteria of the Japanese Research Society for Portal Hypertension. The relationship between the recurrence of esophageal varices and factors such as biochemical and hematological parameters, as well as the etiology of the liver disease, was analyzed using the Kaplan-Meier method and the multivariate Weibull regression model. Results. PBC patients had an earlier recurrence of esophageal varices compared to non-PBC patients, and two factors, prothrombin time and etiology (PBCon-PBC), were indicative of significantly earlier recurrence of esophageal varices. Conclusions. We should be extra careful in the follow-up of patients with PBC after therapy for esophageal varices.
