Individualized dorsal basal segment (S10) resection using intersegmental veins as the landmark

Area of Science:

• Thoracic surgery
• Pulmonary medicine
• Surgical oncology

Background:

• Individualized thoracoscopic dorsal basal (S10) resection is a complex surgical procedure.
• Identifying anatomical landmarks is crucial for successful S10 segmentectomy.

Purpose of the Study:

• To detail the role of intersegmental veins (inter-SVs) in facilitating S10 resection.
• To evaluate the safety and efficacy of using inter-SVs as a landmark for S10 segmentectomy.

Main Methods:

• Retrospective review of patients undergoing individualized S10 resection from January 2015 to September 2020.
• Utilized inter-SVs as a landmark for surgical planning and segmentectomy.
• Compared outcomes with lower lobectomy.

Main Results:

• 46 patients underwent individualized S10 resection with R0 resection and a mean margin of 22.45 mm.
• No conversions to extended resection were necessary.
• Comparable blood loss, hospital stay, and air leak rates were observed between segmental and lobar resections.

Conclusions:

• Inter-SV-guided strategy facilitates S10 nodule resection planning and execution.
• This approach aids bronchial recognition and intersegmental plane division.
• Further long-term studies are needed to confirm clinical benefits.
