Anatomic Segmental Resection
The operative modes for pulmonary parenchymal resection include pneumonectomy, bilobectomy, lobectomy, segmental resection (segmentectomy), and wedge resection, according to the extent of lung parenchyma to be resected. From the perspective of the technical features at the pulmonary hilum, these may be divided into anatomic (pneumonectomy, bilobectomy, lobectomy, and segmentectomy) and nonanatomic (wedge) resections. In anatomic resection, the extent of pulmonary parenchyma for resection is determined according to the extent of perfusion of pulmonary vessels as well as by the extent of aeration of the bronchi, which are divided at the hilum. On the other hand, in nonanatomic resection, the extent of parenchymal resection is determined solely according to the location of the target lesion. Although segmentectomy and wedge resection are both referred to as sublobar resection, their technical characteristics are quite different.
