Open versus Thoracoscopic RFA-Assisted Lung Resection

Area of Science:

• Thoracic Surgery
• Minimally Invasive Procedures
• Radiofrequency Ablation Technology

Background:

• Lung parenchymal transection is a critical step in surgical resection.
• Traditional methods can lead to complications such as bleeding and air leaks.
• Radiofrequency Ablation (RFA) offers a potential alternative for tissue cutting and sealing.

Purpose of the Study:

• To evaluate the safety and efficacy of Radio Frequency Ablation (RFA)-assisted lung parenchymal transection.
• To compare RFA-assisted lung resection via thoracotomy versus thoracoscopy.

Main Methods:

• Twelve domestic pigs underwent RFA-assisted lingulectomy.
• Six pigs in Group A underwent thoracotomy, while six in Group B underwent thoracoscopy.
• Intraoperative and postoperative outcomes were monitored, including bleeding, air leaks, and complications.

Main Results:

• No mortality, bleeding, or air leaks occurred in either group.
• Thoracoscopic RFA (Group B) showed no conversions to open surgery and fewer complications.
• Histopathology confirmed precise coagulation necrosis without adjacent tissue damage.
• Thoracotomy (Group A) was associated with longer operating times, pleural adhesions, barotrauma, skin burns, and infection.

Conclusions:

• RFA-assisted lung resection is a safe and effective technique.
• Thoracoscopic RFA maintains the benefits of minimally invasive surgery.
• RFA-assisted thoracoscopic lung resection is a viable and safe option for experienced surgeons.
