Thoracoscopic left upper division (S1/2/3) resection: alternative posterior approach

Area of Science:

• Thoracic Surgery
• Surgical Oncology

Background:

• Minimally invasive pulmonary segmentectomy offers oncological treatment with lung preservation and reduced morbidity.
• Left upper division resection (S1, S2, S3 trisegmentectomy) can be complex due to anatomical structures like the lingula obstructing visualization and instrument movement, particularly with an anterior approach.

Discussion:

• A posterior surgical approach provides superior access to the segmental artery and bronchus for S1, S2, S3 trisegmentectomy.
• This approach facilitates dissection away from critical structures, especially when enlarged lymph nodes are present between the bronchus and artery.
• The posterior approach aids in safely isolating and encircling the bronchus, with the artery already mobilized.

Key Insights:

• The posterior approach significantly enhances surgical maneuverability and visualization during left upper division trisegmentectomy.
• This technique is particularly advantageous in complex cases involving pathological nodes, simplifying dissection.
• Despite the approach, S1/S2/S3 trisegmentectomy requires meticulous surgical technique.

Outlook:

• Further evaluation of the posterior approach for complex trisegmentectomies may refine minimally invasive lung cancer treatment.
• Standardizing this technique could improve outcomes for patients requiring resection of the left upper division.
• Continued research into optimizing surgical strategies for segmentectomies is crucial for advancing thoracic surgery.
