    【Abstract】 Objective To study the feasibility of evaluation of therapeutic efficacy of intraoperation ultrasound guided radiofoequency ablation(RFA) in patients with hepatic caudate lobe tumor using ultrasonograply.Methods 7 patients with hepatic caudate lobe tumor were submitted to intraoperation ultrasound guided RFA Ultrasonograply, were performed preoperatively, intraoperatively and postoperatively to detect the echo,size and blood supply of the lesions.Results Intraoperation ultrasound showed that the ablated lesions were smaller significantly than the preoperative lesions.Conclusion Ultrasonograply is a convenient,cost-effective and reliable modality for evaluation of therapeutic efficacy of intraoperation ultrasound guided RFA of hepatic caudate lobe tumor, and is recommended as a feasible method. ......
