Two-Way: A Novel Method for Identifying the Anatomy During Uniportal Thoracoscopic Segmentectomy.

Because the segmental bronchi and vessels are commonly variable and complicated, it is difficult to correctly identify them. Misidentification of the segmental anatomy could result in the failure of segmentectomy and conversion to other surgical procedures such as bisegmentectomy or lobectomy. We describe a novel method to identify the target segmental vessels and bronchi by exposing the adjacent segmental anatomy during uniportal video-assisted thoracoscopic segmentectomy, which could help to reduce the chance of misidentification.
