Endoscopic radiofrequency ablation may be preferable in the management of malignant biliary obstruction: A systematic review and meta-analysis.

Objective: Endoscopic biliary radiofrequency ablation (RFA) has been increasingly used to treat unresectable malignant biliary obstruction (MBO). We aimed to perform this systematic review and meta-analysis to evaluate the efficacy and safety for the treatment of malignant biliary obstruction (MBO) and its impact on patient's survival.

Methods: A comprehensive search of the Cochrane Library, PubMed and EMBASE databases was conducted.

Clinical outcome of endoscopic covered metal stenting for resolution of benign biliary stricture: Systematic review and meta-analysis.

Background And Aim: Management of benign biliary stricture is challenging. Endoscopic therapy has evolved as the first-line treatment for various benign biliary strictures. However, covered self-expandable metal stents (CSEMS) have not been approved by the United States Food and Drug Administration for the treatment of benign biliary stricture.
