BackgroundThe detection rate of bilateral multiple pulmonary nodules (BMPNs) is increasing due to widespread use of chest computed tomography (CT) screening. However, there is no consensus on the treatment options for BMPNs and whether simultaneous bilateral pulmonary resection is safe remains controversial. The purpose of this study was to evaluate the feasibility and safety of simultaneous bilateral pulmonary resection for BMPNs.MethodsA total of 16 consecutive patients with BMPNs who underwent simultaneous bilateral pulmonary resection in Beijing Hospital from June 2013 to July 2020 were enrolled in this study. Clinical characteristics, imaging and pathological features, and perioperative outcomes were retrospectively reviewed.ResultsThere were 10 males and six females included in the study with a mean age of 61.9 (range: 39–78) years. A total of 35 nodules were resected in 16 patients including 12 patients with bilateral primary lung cancer, three patients with primary lung cancer on one side and a benign nodule on the contralateral side, and one patient with bilateral benign nodules. All patients underwent bilateral pulmonary resection via single‐utility port video‐assisted thoracoscopic surgery (VATS). Nine, four, two, and one patients underwent lobectomy with contralateral segmentectomy or wedge resection, segmentectomy with contralateral wedge resection, bilateral segmentectomy and bilateral wedge resection, respectively. All operations were accomplished successfully without intraoperative blood transfusion, conversion to thoracotomy, major complication and postoperative 90‐day death. The mean operation time was 220.1 ± 65.6 minutes, median thoracic drainage duration was four days (range: 2–8 days), mean pleural drainage was 1387.5 ± 694.7 mL, and median postoperative hospital stay was seven days (range: 5–18 days). There were three cases (18.8%) of minor complications, including one case of pulmonary air leakage, one case of atrial fibrillation, and one case of poor healing of surgical site. A total of 50% (8/16) of the patients had severe postoperative pain and required additional analgesia.ConclusionsFor selected patients, simultaneous bilateral pulmonary resection via single‐utility port VATS is a safe and feasible minimally invasive procedure for BMPNs. Adequate postoperative analgesia via a multimodal analgesia strategy should be used to prevent postoperative pain.Key pointsSignificant findings of the studyThe incidence of major complication after minimally invasive bilateral pulmonary resection is low for patients with good pulmonary function, but there is a relatively high incidence of minor complications and pain at the surgical site. Adequate postoperative analgesia via multimodal analgesia strategy should be used to prevent postoperative pain.What this study addsFor the treatment of bilateral multiple pulmonary nodules, simultaneous bilateral pulmonary resection via single‐utility port video‐assisted thoracoscopic surgery is safe and feasible for selected patients.
