Abstract

Background: Endoscopic measures such as balloon dilation can relieve obstruction and improve symptoms in patients with primary sclerosing cholangitis (PSC). However, the influence of repeated endoscopy to maintain biliary patency on the survival of patients with PSC is unclear. Methods: This study evaluated the impact of endoscopic therapy on the survival of consecutive patients with PSC undergoing endoscopic therapy. During a 6-year period 63 patients underwent endoscopic therapy. After initial therapy, patients were followed for a median of 34 months. Endoscopic therapy primarily consisted of repeated balloon dilation of dominant biliary strictures. The observed survival of this cohort was estimated (Kaplan-Meier). The predicted survival of the cohort was estimated by using the Mayo Clinic survival model based on clinical information obtained within 3 months before first endoscopic therapy. The Mayo Risk Score was calculated by using the equation R = (0.03 Age, years) + (0.54 loge Bilirubin mg/dL) + (0.54 loge Aspartate aminotransferase U/mL) + (1.24 Bleed history) - (0.84 Albumin gm/dL). Results: The observed survival over 5 years was significantly higher than the predicted 5-year survival (83% vs. 65%, respectively; p = 0.027). Conclusion: These data suggest that repeated endoscopic attempts to maintain biliary patency may improve the survival of patients with PSC and dominant strictures.
