Abstract

Surgical resection remains the curative procedure for liver tumors, but even with improvements in method it is still a major operation with significant morbidity and mortality in experts' hands, and a long learning curve for those surgeons who undertake it. Recently radiofrequency ablation has gained some credibility as an alternative method of dealing with liver tumors deemed unresectable. A novel technique of liver resection assisted by the application of radiofrequency is described here. A patient with colorectal liver metastases underwent a segment II/III liver resection with this technique. Following laparotomy, the tumor was identified with intraoperative ultrasound and a 'cooled-tipped' radiofrequency probe was used to ablate liver parenchyma 2cm away from the edge of the tumor. To achieve full thickness of radiofrequency ablation, several insertions were applied. The effect of radiofrequency on liver parenchyma was monitored with an intraoperative ultrasound by micro-bubbles generated by radiofrequency ablation. The length of the resection was 45 min with a blood loss of 30mL. The patient was discharged on the 6th postoperative day without complications. In this report we indicate how the use of radiofrequency ablation can be combined with standard surgical resection of liver cancers to provide a quick, and relatively bloodless operation that is likely to reduce morbidity and mortality and is easy for its practitioners to learn
