ABSTRACT: To assess the feasibility and safety of radiofrequency ablation (RFA) with hand-assisted laparoscopic surgery (HALS) for hepatocellular carcinoma (HCC) in the caudate lobe with severe liver dysfunction.
HCC in the caudate lobe remains one of the most difficult locations where various treatments tend to pose problems regarding the optimal surgical approach. The technique of HALS has thus been proposed as a useful method for performing a safe RFA therapy. For this study, we assessed the feasibility and safety of RFA with HALS for the treatment of HCC in the caudate lobe with liver dysfunction.
Between July 1999 and February 2005, 5 patients who suffered from HCC in the caudate lobe were indicated for RFA. The percutaneous puncture was difficult and all patients have severe liver dysfunction with viral chronic hepatitis. Therefore, RFA was assisted by an inserted hand through a minimal skin incision under laparoscopic inspection. An intraoperative endoscopic ultrasound examination was performed before RFA to determine the tumor region. The hand-assisted minimal dissection around the caudate lobe was required to detect tumor and avoid injuries of other tissues. RFA for HCC was performed using a cooled-tip (Radionics Inc, Burligton, MA) connected to a RF generator under the programmed cyclic impedance.
The surgical procedures consisted of 5 RFA to tumors in the caudate lobe with HALS, which was performed safely, and a postoperative computed tomography scan revealed a sufficient ablation in all patients. There was no operative mortality but 1 patient had minor bile leakage, which was treated conservatively, and all patients recovered and thus were eventually discharged. One patient had local recurrence after 3 months, 3 patients had tumor recurrences in another segment after 6 months. At a mean follow-up 32.2 months, all patients were still alive.
RFA with HALS is considered to be a safe and feasible technique for HCC in the caudate lobe with liver dysfunction.
