Anatomic Segmentectomy in Nonintubated Video-Assisted Thoracoscopic Surgery.

Thoracic surgery has evolved into minimally invasive surgery, in terms of not only surgical approach but also less aggressive anesthesia protocols and lung-sparing resections. Nonintubated anatomic segmentectomies are challenging procedures but can be safely performed if some essentials are considered. Strict selection criteria, previous experience in minor procedures, multidisciplinary cooperation, and the 4 cornerstones (deep sedation, regional analgesia, oxygenation support and vagal blockade) should be followed. Better outcomes in postoperative recovery, including resumption of oral intake, chest tube duration, and hospital stay, and low complication and conversion rates, are encouraging but should be checked in larger multicenter prospective randomized trials.
