The objective of this study was to determine the safety and efficacy of percutaneous endobiliary radiofrequency ablation (ERFA) and balloon dilation for the treatment of hepaticojejunostomy (HJ) strictures resistant to surgery and/or other interventions.

Eighteen patients who underwent percutaneous ERFA for HJ stricture were included. There were 10 men and 8 women with a mean age of 48.3±10.8 (SD) years (range: 33–69 years). The 18 patients had a total of 29 benign HJ strictures secondary to cholecystectomy (14 patients; 78.0%), Whipple procedure (3 patients; 16.6%) or blunt abdominal trauma (1 patient; 5.4%). The different end-points were technical success, clinical success, recurrence, procedure-related mortality, and morbidity.

Technical and clinical success rates were 100% and 83.3%, respectively. No mortality and major procedure-related complications were observed. One patient experienced minor complication (self-limited pleural effusion). Two patients did not show favorable response to ERFA whereas 10 patients had no stricture recurrence during a mean follow-up period of 7.3 months±1.0 (SD) (range: 4–10 months).

ERFA is a safe and effective treatment for benign HJ and biliary strictures. However, more studies involving more patients with a long-term follow-up period should be made to fully determine the long-term results of ERFA.
