Abstract

 

Purpose: To evaluate the feasibility and safety of long-term balloon indwelling technique for the treatment of single benign biliary stricture.

 

Methods: Five patients with single benign biliary stricture were included from December 2014 to November 2016. The patients were 3 men and 2 women with an average age of 50.0 years (30 to 65 years). A balloon catheter was inserted into the drainage catheter and emerged through the side hole of the catheter so that the balloon and drainage catheters could be placed together at the stricture site. Follow-up fluoroscopic examination was performed once within at least 2 weeks to evaluate the adequacy of expansion and location of the balloon. The balloon was reinflated at each session, and then removed after an approximately two-month indwelling period.

 

Results: The catheters used were 10 to 16-French and the diameter of indwelling balloons were 4 to 8 mm. The primary technical success rate and clinical success rate were 100%. Maintenance of the balloon location was achieved in 25 of 26 follow-up fluoroscopic examination (average 5.2 times per a patient) with a rate of 96.1%. The mean follow-up period after successful removal of the balloon was 542.2 days (93-1,042 days), and there were no recurrences in the 5 cases.

 

Conclusion: The long-term balloon indwelling technique is a good way to induce maximal dilatation at the stricture site without large diameter skin and subcutaneous tract dilatation and can be successfully used for single benign biliary stricture.
