All patients were followed up until death or at least one year after the procedure. Kaplan-Meieranalysis was used to compare the survival of the patients and the rates of stent patency.RESULTS: The 30-day mortality rate was lower in the MS group (6/61, 9.8%) than in the PS group(9/34, 26.5%, P【0.05). The 30-day reobstruction rate and the complication rate were 15.0%, 16.4%in the MS group and 32. 4%, 29. 4% in the PS group, respectively (P【0. 01). The median patencyperiod of stents and median survival period of the patients were 230 days, 224 days in the MS group and90 days, 94 days in the PS group, respectively (P【0. 01).CONCLUSION: Metal stent is clinically superior to plastic stent in the treatment of malignant biliaryobstruction.展开更多
