Background: Recent development in minimally invasive thoracic surgery for lung cancer includes a combination of nonintubated anesthetic management and sublobar resection in patients with compromised cardiopulmonary function or with early-stage lung cancer.
Methods: From August 2009 to December 2016, 89 patients with lung cancer underwent thoracoscopic anatomical segmentectomy without endotracheal intubation, using a combination of thoracic regional anesthesia and targeted sedation during surgery.
Results: There were 28 patients (31%) undergoing compromised nonintubated thoracoscopic anatomical segmentectomy due to advanced age or poor lung function reserve. Left upper apical trisegmentectomy was most commonly performed (n=21), followed by left upper lingulectomy (n=16) and right upper superior segmentectomy (n=15). Conversion to intubated general anesthesia was required in two patients because of vigorous mediastinal movement. No patient required conversion to a thoracotomy or lobectomy. Prolonged chest tube drainage was noted in three patients who had air leak (n=2) or chylothorax (n=1). The median chest drainage and hospital stay were 2 and 4 days, respectively. The median time of anesthetic induction and operation were 15 and 135 minutes, respectively.
Conclusions: Nonintubated thoracoscopic anatomical segmentectomy is safe and technically feasible using regional thoracic anesthesia and conscious sedation. In selective lung cancer patients, a less invasive nonintubated thoracoscopic segmentectomy can be an alternative to intubated one-lung ventilation or to a complete lobectomy.
