Clinical effect of radiofrequency ablation in treatment of hepatic hemangioma

Objective To investigate the clinical effect and application experience of radiofrequency ablation in the treatment of hepatic hemangioma. Methods A retrospective analysis was performed for the clinical data of 34 patients with hepatic hemangioma who underwent radiofrequency ablation in Beijing You'an Hospital from January 2011 to June 2015. Among these patients,22 underwent ultrasound- guided percutaneous transhepatic radiofrequency ablation( PRFA),10 underwent laparoscopic radiofrequency ablation( LRFA),and 2 underwent open hepatectomy combined with hepatic hemangioma radiofrequency ablation( OHRFA). The intraoperative and postoperative conditions were compared between patients undergoing different methods of radiofrequency ablation. Results All the patients underwent successful radiofrequency ablation. The mean time of operation in PRFA group,LRFA group,and OHRFA group was 75. 45 ± 27. 33 min,97. 90 ±32. 37 min,and 192. 5 min,respectively,and the median hospital stay in these groups was 3 d,3 d,and 10. 5 d,respectively. There were no serious complications during and after surgery. The complete remission rate at 1 month after surgery was 94. 1%( 32 /34). The patients were followed up for 6- 24 months and no recurrence was observed. Conclusion Radiofrequency ablation is a safe and effective procedure for the treatment of hepatic hemangioma. Strict control of surgical indications and selection of proper radiofrequency ablation approach are of great importance.
