Abstract:Objective: To investigate the feasibility and safety of radiofrequency ablation for percutaneous difficult liver cancer with enhanced-contrast ultrasound combined with real-time imaging virtual navigation system. Methods: Forty-one patients with 52 lesions in the experimental group were treated with radiofrequency ablation assisted by enhanced-contrast ultrasound combined with real time virtual imaging navigation system. In the control group of 40 patients with 54 lesions were treated with radiofrequency ablation guided by enhanced CT or guided by ultrasound after laparoscopic and open the abdomen, and the differences in operative and postoperative complications, residual and recurrence rates were compared between the two groups. Results: Fifty-two lesions in the experimental group successfully completed ultrasound and CT or MRI image fusion, the image fusion success rate was 100%, and the image alignment time was 10~30 min, with an average of 15.2 min. Three of the 81 patients in the two groups developed serious complications during and after treatment, including one case of ruptured tumor hemorrhage, one case of bloody chest water, and one case of liver abscess. No serious complications occurred in the remaining cases. There was a statistically significant difference between the two groups in pain score, bleeding and fever(P<0.05). The pain score, the probability of bleeding and postoperative fever of the experimental group were all lower than those of the control group. There was no significant difference in the recurrence rate between the two groups after treatment in three and six months. Conclusion: The radiofrequency ablation of percutaneous liver cancer treated with ultrasound combined with real time imaging virtual navigation system has low incidence of residual and recurrence rate, pain and hemorrhage complications, and is feasible and safe.
