EUS-guided biliary drainage using a fully covered self-expandable metal stent for malignant obstructive jaundice / 中华肝胆外科杂志

ABSTRACT

Objective To study the therapeutic effects of EUS-guided biliary drainage (EUS-BD) using a nitinol fully covered self-expandable metal stents in patients with malignant obstructive jaundice after failed ERCP.Methods From January 2016 to January 2018,all patients with malignant obstructive jaundice who failed ERCP underwent EUS-guided biliary drainage using nitinol fully covered self-expandable metal stent at Affiliated Hangzhou First People' s Hospital,Zhejiang University School of Medicine.The operation success rate,liver functional recovery time,complication rate,length of hospital stay and survival time were observed.Results Of 36 patients who underwent EUS-guided biliary drainage,34 were successfully performed,with 19 through the stomach,and 15 through the duodenum.The operation success rate was 94.4％ (34/36).The liver functional recovery time of the 34 patients were 25.8 ±.6.5 days.One patient developed hemobilia and one cholangitis,both improved after conservative treatment.The total complication rate was 5.6％ (2/36).The hospital stay and survival time were 21.5 ± 4.7 days and 220.5 ± 54.8 days,respectively.Conclusion EUS-BD using nitinol fully covered self-expandable metal stents was a feasible and effective treatment in patients with malignant biliary obstruction after failed ERCP.
