This study presents a modified thoracoscopic S9 segmentectomy technique that avoids dividing the intersegmental plane. This approach simplifies the procedure and is beneficial for cases with incomplete interlobar fissures.

Area of Science:

Thoracic Surgery
Surgical Techniques
Pulmonary Medicine

Background:

Conventional lateral basal (S9) segmentectomy involves dividing the intersegmental plane between superior and anterior segments.
This division can lead to additional parenchymal splitting, potentially complicating the procedure.

Purpose of the Study:

To introduce a modified thoracoscopic S9 segmentectomy technique.
To highlight the advantages of dissecting along intersegmental veins instead of dividing the intersegmental plane.

Main Methods:

A modified thoracoscopic S9 segmentectomy technique based on dissection along intersegmental veins.
The technique avoids division of the intersegmental plane between the superior and anterior segments.

Main Results:

The modified technique avoids additional parenchymal splitting from the superior segment.
This method is applicable even when an incomplete interlobar fissure is present.

Conclusions:

The modified thoracoscopic S9 segmentectomy offers a simpler and potentially safer approach.
This technique expands the applicability of S9 segmentectomy in challenging anatomical situations.
