Background: The use of a new enfire type laparoscopic US probe with a forward-viewing convex-array transducer allows the caudate lobe of the liver to be accessed. This study evaluated the preliminary results of treatment of hepatocel lular carcinoma in the caudate lobe by using this new instrument. Methods: Three patients with hepatocellular carcinoma in the caudate lobe were selected. A laparoscopic US probe, with a forward-viewing convex-array transducer at the tip and a guide groove for puncture on the back, was used to monitor the position of the radiofrequency ablation needle during the treatment. Results: Ablation was performed without complication in all cases. Complete necrosis of the tumor was confirmed by postoperative CT. At a mean follow-up of 30.3 months, no local recurrence was observed in any patient. Conclusions: Radiofrequency ablation of hep atocellular carcinoma in the caudate lobe of the liver by using a new laparoscop ic US probe with a forward-viewing convex-array transducer at the tip was safe and effective.
