Nonintubated uniportal video-assisted thoracoscopic surgery for primary spontaneous pneumothorax

The objective of the current study was to evaluate the feasibility and safety of nonintubated uniportal video-assisted thoracoscopic surgery (VATS) for the management of primary spontaneous pneumothorax (PSP).

From November 2011 to June 2013, 32 consecutive patients with PSP were treated by nonintubated uniportal thoracoscopic bullectomy using epidural anaesthesia and sedation without endotracheal intubation. An incision 2 cm in length was made at the 6(th) intercostal space in the median axillary line. The pleural space was entered by blunt dissection for placement of a soft incision protector. Instruments were then inserted through the incision protector to perform thoracoscopic bullectomy. Data were collected within a minimum follow-up period of 10 months.

The average time of surgery was 49.0 min (range, 33-65 min). No complications were recorded. The postoperative feeding time was 6 h. The mean postoperative chest tube drainage and hospital stay were 19.3 h and 41.6 h, respectively. The postoperative pain was mild for 30 patients (93.75%) and moderate for two patients (6.25%). No recurrences of pneumothorax were observed at follow-up.

The initial results indicated that nonintubated uniportal video-assisted thoracoscopic operations are not only technically feasible, but may also be a safe and less invasive alternative for select patients in the management of PSP. This is the first report to include the use of a nonintubated uniportal technique in VATS for such a large number of PSP cases. Further work and development of instruments are needed to define the applications and advantages of this technique.
