Aims: The effect of ursodeoxycholic acid (UDCA) treatment on survival and liver histological progression of primary sclerosing cholangitis (PSC) remains uncertain. The aim of the present study was to evaluate the effect and safety of UDCA in PSC. Methods: Electronic databases including Medline, Embase, Cochrane controlled trials register, Web of Science and PubMed (updated to January 2009) and manual bibliographical searches were carried out. A meta‐analysis of all randomized controlled trials (RCT) comparing UDCA with placebo or no treatment was carried out. Results: Eight RCT including 465 patients were assessed. UDCA could significantly improve liver biochemistry, but had no effect on pruritus and fatigue. Meta‐analysis of the included RCT showed UDCA had no significant effect on the incidence of death, liver transplantation, and death and/or liver transplantation. However, a significant difference for the incidence of histological improvement was found between the two groups (odds ratio [OR], 9.19; 95% CI: 0.98, 86.15; P = 0.05). Meta‐analysis also indicated a reduction trend of histological deterioration and an improvement trend of cholangiographic changes. These trends were constant in the sensitivity analyses. Conclusion: The meta‐analysis found that UDCA can improve liver biochemistry and there is a trend towards improvement in liver histology and cholangiography, but has no effect on survival free of transplantation.
