Thoracoscopic left mediastinal lymph node dissection.

Area of Science:

• Thoracic Surgery
• Surgical Oncology

Background:

• Video-assisted thoracoscopic surgery (VATS) use for primary lung cancer is rising in Japan.
• Mediastinal lymph node dissection via VATS presents challenges compared to thoracotomy.

Purpose of the Study:

• To present novel VATS techniques for improved mediastinal lymph node dissection in lung cancer surgery.
• To address difficulties in subcarinal and left upper lymph node dissection using VATS.

Main Methods:

• Description of two techniques for left-sided subcarinal lymph node dissection.
• Technique involves specific retraction and dissection order to maintain surgical view.
• Method for left upper mediastinal lymph node dissection using recurrent laryngeal nerve traction.

Main Results:

• The described techniques facilitate effective subcarinal lymph node dissection from the left thoracic cavity.
• A specific maneuver allows for easier dissection of the #4L lymph node.
• No instances of recurrent nerve paralysis were observed with the described left upper mediastinal technique.

Conclusions:

• These VATS techniques enhance the efficacy and safety of mediastinal lymph node dissection for lung cancer.
• The presented methods offer solutions for challenging lymph node dissections in VATS procedures.
• Further adoption of these techniques could improve oncological outcomes in lung cancer surgery.
