Simultaneous Uniportal video-assisted thoracic surgery of bilateral pulmonary nodules

Surgical resection is an appropriate treatment option for synchronous bilateral pulmonary nodules with ground-glass opacities. The applicability of simultaneous uniportal video-assisted thoracic surgery is not fully understood. We evaluated the feasibility and safety of performing such surgeries at our hospital. Clinical data of 35 patients who underwent simultaneous bilateral pulmonary resection with uniportal video-assisted thoracic surgery at our hospital were reviewed retrospectively. Simultaneous bilateral pulmonary resection with uniportal video-assisted thoracic surgery was performed for 35 patients (15 men, 20 women); 97 nodules were operated on, and the average nodule diameter was 11.4 mm (range, 1-38 mm). Computerized tomography showed that most nodules had ground-glass opacity (52/97, 53.6%); solid nodules (24/97, 24.7%) and nodules with mixed ground-glass opacity (21/97, 21.7%) were noted. Surgical resection included lobar-sublobar resection (11/35, 31.4%) and sublobar-sublobar resection (24/35, 68.6%). Wound infection and postoperative 30-day mortality were not observed. Pneumonia was the major postoperative complication, with a higher incidence in the lobar-sublobar group (6/10, 60%) than in the sublobar-sublobar group (4/25, 16%; P = 0.016). Pneumonia did not correlate with operative time (mean, 262.3 ± 108.1 vs. 261.9 ± 87.5 min, P = 0.991), duration of chest drainage (mean, 7.0 ± 4.0 vs 5.4 ± 2.1 days, P = 0.124), and postoperative hospital stay (mean, 10.2 ± 3.6 vs 10.2 ± 6.4 days, P = 0.978). The mean follow-up time was 8 (range, 3-22) months. Recurrence of primary lung cancer or mortality was not noted at the final follow-up. Simultaneous bilateral pulmonary resection with uniportal video-assisted thoracic surgery is feasible and safe for appropriate patients. Simultaneous lobar-sublobar pulmonary resection for bilateral nodules can increase the risk of developing pneumonia.
