Current consensus on the management of primary sclerosing cholangitis.

Guidelines for the management of primary sclerosing cholangitis (PSC) have recently been published by both the European Association for the Study of the Liver (EASL) and the American Association for the Study of Liver Diseases (AASLD). The current review focuses on the management of PSC, based on these guidelines. There is no established medical therapy for PSC. The role for UDCA in slowing the disease progression and improving survival is as yet unclear, and there are no specific recommendations for the general use of UDCA in this condition. Guidelines recommend that dominant bile duct strictures with significant cholestasis should be treated with biliary dilatation, with or without stenting. Prospective studies to define type, duration, optimal frequency and long-term effects of endoscopic therapy are needed. Liver transplantation is recommended for end stage disease and has excellent results. PSC patients with dysplasia in biliary brush cytology specimens should also be considered for transplantation. There is no evidence-based algorithm for the follow-up of PSC patients, but some regular investigations are recommended (surveillance colonoscopies in patients with IBD and ultrasound to detect gallbladder mass lesions).
