Meta Analysis Comparative StudyMeta-analysis of randomized trials comparing the patency of covered and uncovered self-expandable metal stents for palliation of distal malignant bile duct obstruction.
Self-expandable metal stents (SEMSs) are used for palliation of malignant biliary obstruction. ⋯ CSEMSs have a significantly longer duration of patency compared with USEMSs in patients with distal malignant biliary obstruction. Stent dysfunction occurs at a similar rate, although there is a trend toward later obstruction with CSEMSs.
