All patients underwent \u22651 unsuccessful cholangioplasty session and upsizing of their transhepatic biliary drains pre-procedure.

Technical success rate was 100% (16\/16). Procedure-related complications occurred in 1\/16 cases (drain leakage with subsequent cellulitis). Clinical success rate was 87% (13\/15) with a median follow-up of 17 (2-24) months. Drain\/stent was not removed in one case (1\/16) as the patient was lost to follow-up immediately post-procedure. The one-year patency rate was 100%. A significant reduction was observed in the median number of IR visits (8 [1-51] to 1 [0-9]; P\u2009=\u2009.003) and drain insertion\/exchange procedures (5 [1-45] to 0 [0-6]; P\u2009=\u2009.003) pre- and post-EB-RFA with a median follow-up of 18 (0-26) months.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Percutaneous EB-RFA can safely and effectively treat refractory benign biliary strictures.
