Abstract: Objective To explore the efficacy and safety of CT-guided radiofrequency ablation （CT-FRA） in the treatment of patients with recurrent small liver cancer at the top of the diaphragm. Methods Sixty-nine patients with recurrent small liver cancer at the top of the diaphragm from February 2013 to April 2015 in our hospital were selected, of which 36 cases were treated with CT-FRA as the CT-FRA group, and 33 cases were treated with laparoscopic radiofrequency ablation （L-FRA） as the L-FRA group. The average ablation time, active tumor residual rate, complications, hospitalization time, hospitalization cost, average survival time, and the local progression rate and overall survival rate of the tumor at 1, 3 years were compared between the two groups. Results There was no significant difference in average ablation time and active tumor residual rate between the two groups （P>0.05）; the hospital stay in the CT-FRA group was shorter than that in the L-FRA group, and the hospitalization cost was lower than that in the L-FRA group （P<0.05）; there was no significant difference in the local tumor progression rate and overall survival rate between the two groups at 1 and 3 years （P>0.05）. Conclusion CT-FRA and L-FRA are effective treatments for recurrent small hepatocellular carcinoma at the top of the diaphragm, but CT-FRA is relatively economical, simple, and safe.
