Aims: to evaluate the effectiveness of a novel up-steer method for laparoscopic ultrasound guidance of radiofrequency ablation for tumors located in hepatic segment VII and VIII.
Methods: all the cases of tumors located in hepatic segment VII and VIII which were treated using laparoscopic ultrasound guided radiofrequency in our department by a single surgeon from February 2015 to August 2017 were retrospectively reviewed. Whether the procedure was performed using an up-steered method, the first puncture duration, the puncture failure time, the complication rate, the ablation area, and the local recurrence rate in one year were all compared.
Results: a total of 64 tumors were enrolled in the present study, including 28 tumors ablated using a novel up-steered method. The overall puncture failure time was 8 times in the up-steered group, and the puncture failure time was 22 times in the conventional puncture group, with a puncture success rate of 77.8% Vs 62.1%, (p=0.086). The average puncture duration was 115.5 ± 114.7 min in the up-steered group, and 151.4 ± 159.9min in the conventional group. There was no significant difference between the complication rate and the ablation area of the two group, and there was no local recurrence in one year after ablation.
Conclusion: the up steered method was helpful when performing the laparoscopic ultrasound guided radiofrequency for tumors located in hepatic segment VII and VIII.
