ABSTRACT
Objective To summarize the efficacy and safety of covered metal stents joint nasobiliary drainage in treated with ERCP-related Ⅲ Stapfer bile duct perforation. Method Covered metal stent were immediately placed with patients for ERCP-related III Stapfer bile duct perforation. Then, nasobiliary drainage were placed. The stents were removed after 2 ～ 4 weeks. Result 6 patients were all improved, and no surgical patients. The effective rate was 100.00％. No stent related complications occurred. The symptoms of abdominal infection occurred in 1 patient during hospitalization, the rate was 16.67％. Conclusion The method of treatment for ERCP-related III Stapfer bile duct perforation was safe and effective, it was worthy of clinical popularization and application.
ABSTRACT
Objective To compare the clinical efficacy of covered and uncovered metal stents in treatment of malignant biliary obstruction. Methods 123 cases of malignant biliary obstruction from May 2003 to May 2014. The survival time, the stent patency rates, the effective and biochemical indexes between the two groups were analyze and compared, follow-up period ended in March 2015. Results The level of bilirubin, transaminase, alkaline phosphatase (ALP) was declined after the covered and uncovered metal stents placed by ERCP, and the results of the two groups had no statistical significance (P > 0.05). Also there was no significant difference of the incidence of postoperative cholangitis and the cumulative survival rate between the two groups (P > 0.05). One year survival rates was related to tumor types (r = -1.55, P < 0.05). Conclusions Covered and uncovered metal stents for malignant biliary obstruction have no statistically significant about remission of liver function, stent occusion and the cumulative survival rate.
