Area of Science:

Thoracic Surgery
Surgical Oncology
Minimally Invasive Procedures

Background:

Thoracoscopic anatomic segmentectomy of basal lung segments presents technical challenges due to deep and variable vasculature and bronchi.
Existing methods may require complex dissection or fissure manipulation.

Purpose of the Study:

To describe and evaluate a novel single-direction method for thoracoscopic basal segmentectomy.
To assess the feasibility, safety, and efficacy of this technique for single or combined basal segment resections.

Main Methods:

Retrospective analysis of 137 patients undergoing thoracoscopic basal segmentectomy between April 2015 and August 2019.
Procedures utilized either an inferior pulmonary ligament approach or an interlobar fissure approach, guided by the single-direction strategy.
The single-direction method involves exposing vessels and bronchi sequentially from superficial to deep.

Main Results:

Ninety patients had single basal segmentectomy, and 47 had combined procedures.
Median operative time was 125 minutes, with median blood loss of 30 mL.
Postoperative morbidity was low at 5.1%, with no perioperative deaths. Median follow-up was 15 months with no recurrence or mortality.

Conclusions:

The single-direction method for thoracoscopic basal segmentectomy is a feasible and safe technique.
This approach simplifies the resection of basal segments by a systematic, superficial-to-deep dissection.
It effectively avoids unnecessary lung splitting and dissection of hypoplastic fissures, facilitating anatomic resection.
