Background: Minimal invasive surgery is current choice of treatment for lung cancer. Combined nonintubated anesthesia with uniportal thoracoscopic surgery is not well understood. Here, we report the experience of nonintubated uniportal thoracoscopic surgery in the treatment of primary non-small cell lung cancer (NSCLC).
Methods: From January 2014 to December 2015, we retrospectively reviewed 131 consecutive patients with primary NSCLC who underwent nonintubated uniportal thoracoscopic wedge resection and mediastinal lymph node dissection at a single medical center.
Results: Of the 131 patients, 110 (84%) received preoperative computed tomography-guided dye localization. Most of them were diagnosed with early stage invasive adenocarcinoma (N=112, 85.5%; pathological stage IA: 84.7%, N=111), and the mean size of the nodule was small (diameter: 0.85±0.40 cm). All section margins were free of malignancy. In total, 7 of the 131 patients (5.3%) had their treatment converted from uniportal to multi-portal video-assisted thoracoscopic surgery (VATS), and 1 (0.8%) had his treatment converted to endotracheal intubation with general anesthesia. The mean operation time was 91.1±32.6 minutes, and the postoperative complications included pneumonia (0.8%), prolonged air leaks (0.8%), and subcutaneous emphysema (1.5%).
Conclusions: Overall, nonintubated uniportal VATS is a feasible, effective and safe procedure for the treatment of early primary lung cancer.
