Percutaneous transhepatic metal versus plastic biliary stent in treating malignant biliary obstruction: a multiple center investigation.

摘要: OBJECTIVE To compare the efficacy of metal versus plastic biliary stent implantation in treatment malignant obstruction. METHODS Percutaneous transhepatic self-expandable (MS, n=61) and 10F (PS, n=34) were placed 95 patients with obstruction three hospitals Guangdong province. All followed up until death or at least one year after procedure. Kaplan-Meier analysis was used to survival rates patency. RESULTS The 30-day mortality rate lower MS group (6/61, 9.8%) than PS (9/34, 26.5%, P<0.05). reobstruction complication 15.0%, 16.4% 32.4%, 29.4% group, respectively (P<0.01). median patency period stents 230 days, 224 days 90 94 CONCLUSION Metal is clinically superior
