OBJECTIVES: To assess the safety and effectiveness of percutaneous endobiliary radiofrequency ablation (EB-RFA) in the management of refractory benign biliary strictures.
METHODS: Percutaneous EB-RFA was performed in 15 individuals (M/F = 8/7; median age: 57 [33-84]) for benign biliary strictures resistant to traditional methods (transhepatic cholangioplasty and biliary drains). All patients underwent ≥1 unsuccessful cholangioplasty session and upsizing of their transhepatic biliary drains pre-procedure. Technical and clinical success were defined as luminal gain with enhanced flow and a lack of clinically evident recurrent stricture on follow-up after drain/stent removal, respectively.
RESULTS: A total of 16 EB-RFA procedures were performed. 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 = .003) and drain insertion/exchange procedures (5 [1-45] to 0 [0-6]; P = .003) pre- and post-EB-RFA with a median follow-up of 18 (0-26) months.
CONCLUSION: Percutaneous EB-RFA can safely and effectively treat refractory benign biliary strictures. However, larger prospective studies with extended follow-ups are needed to gather more robust data.
ADVANCES IN KNOWLEDGE: This study contributes to the limited evidence on the role of EB-RFA in addressing refractory benign biliary strictures, enhancing the understanding of its clinical utility.
