Posterior approach to thoracoscopic pulmonary segmentectomy of the dorsal basal segment: A single-institute retrospective review

The posterior approach for port-access thoracoscopic segmentectomy at S10 or S9+10 is technically challenging, but in our hands it has been feasible. It exposes the targeted bronchus (B10, B9+10) and artery (A10, A9+10) and enables anatomic S10 and S9+10 segmentectomy while avoiding inessential parenchymal splitting from the major fissure.
