Abstract
: Minimally invasive approaches to segmentectomy have grown in popularity as sublobar resection has been increasingly offered as a parenchyma-sparing alternative to lobectomy for amenable lesions. Both video-assisted thoracic surgery and robotic surgery offer advantages over traditional thoracotomy, with fewer complications, shortened hospital stay, and less pain. While segmentectomy has been traditionally performed by video-assisted thoracic surgery, the robotic approach represents a growing subset of minimally invasive sublobar resections. Patient selection for robotic segmentectomy involves a standard preoperative evaluation including pulmonary function tests, cardiac evaluation, and complete staging. Preoperative axial imaging is essential in choosing patients with lesions amenable to segmentectomy, and evaluating the segmental anatomy. Safe robotic segmentectomy centers around thorough knowledge of the segmental vascular and bronchial anatomy and its variants, and preoperative imaging can help the surgeon anticipate variant anatomy intraoperatively. The operative technique generally involves a mediastinal lymph node dissection with frozen section of the N1 nodes and conversion to lobectomy if positive. The segmental resection then proceeds depending on the individual segment to be resected, but generally involves dissection and division of the vessels and bronchus, followed by division of the parenchyma along the intersegmental plane. For most patients, postoperative recovery is short and uncomplicated, with most patients being discharged on the first or second postoperative day.
