Laparotomy and Cool-tip radiofrequency ablation for large liver tumors: short-term results / 中华肝胆外科杂志

ABSTRACT

Objective To study the results of laparotomy and Cool-tip radiofrequency ablation to treat large liver tumors.Methods Laparotomy and Cool-tip radiofrequency ablation were carried out on 64 patients with large hepatic cancer.To destroy the tumor completely,for tumors of 3.0～4.0 cm in diameter,7 ablations were required; for 4.0～5.0 cm in diameter 15 ablations; for 5.0～6.0 cm in diameter 19 ablations; for 6.0～7.0 cm in diameter 40 ablations.Result The complete necrosis rate of laparotomy and radiofrequency ablation was 93.75％ (60/64).The short-term results were good.Conclusions Laparotomy and Cool-tip multipoint overlapping radiofrequency ablation for large liver tumors (tumor diameter＞3 cm) could result in a high complete necrosis rate and a low complication rate.It is a good radical treatment for unresectable and large liver cancer.
