Efficacy of inside metallic stent for benign biliary stricture which persisted after plastic stenting: Multicenter prospective observational study
- Conditions
- Benign biliary stricture
- Registration Number
- JPRN-UMIN000027599
- Lead Sponsor
- Okayama University Hospital Department of Gastroenterology
- Brief Summary
The technical success rate of intraductal FCSEMS placement was 100% The rate of successful stent removal at four months was 100% and stricture resolution was observed in 91% of patients. Bile leak due to guidewire injury occurred in one patient, but stent migration or stent-induced de novo stricture did not occur in any patient. The stricture recurrence rate was 16%, and the median(interquartile range)follow-up duration was 2.8(1.6-3.3)years. 1-year and 2-year recurrence free rate were 89% and 84%
