Anatomical video-assisted thoracoscopic surgery segmentectomies based on the three-dimensional reformation images.

Segmentectomy was first done in 1939 by Churchill and Belsey in 1939. Video-assisted thoracoscopic surgery (VATS) segmentectomies are still more technically challenging than VATS lobectomies. With the increasing rate of early stage lung carcinomas, the thoracoscopic segmentectomies may have a major role in a near future. Four anatomical VATS segmentectomy videos clips were shared in this study. CT three-dimensional reformation could exactly show the small pulmonary nodule's precise position, clarifies the surrounding structures' relationship like the pulmonary artery (PA), pulmonary vein (PV), bronchus (B), fissure, and lymph nodes. Besides, the resection margin, skin incision, surgical approach can also be designed preoperatively. This feasible technique could increase the confidence for thoracic surgeons. Unnecessary explore time waste for locating small pulmonary nodules during the operation can be avoid, so the surgical accuracy can be improved, complications can be prevented, the duration of chest tube and length of hospital stay can be shortened.
