Background:
The aim of this study was to assess the feasibility, efficacy, and safety of video-assisted lingula resection using radiofrequency ablation (RFA) with internally cooled electrodes in a porcine model.
Materials And Methods:
Six domestic pigs underwent RFA-assisted thoracoscopic lingulectomy. RFA was the only aerostatic and hemostatic method applied throughout the operation. After 30 d, the animals were sacrificed for the study of the macroscopic and microscopic effects of the technique.
Results:
No signs of pneumothorax, blood loss, or infection were observed up to 1 mo postoperatively. There was no mortality either during or after surgery. The histopathology of the lung revealed three clearly demarcated zone lesions.
Conclusions:
Our study demonstrates that thoracoscopic lingulectomy using RFA energy is technically feasible. RFA energy is an effective and safe aerostatic and hemostatic method in the porcine model.
