Abstract

BackgroundOur study aims to explore the feasibility of uniportal video-assisted complex sleeve lung resection and summarize the surgical techniques and clinical outcomes.MethodsFrom June 2016 to April 2020, a total of 20 complex sleeve pulmonary and distal tracheal resections were performed by the single surgical team at the Thoracic Surgery Department of the Shanghai Pulmonary Hospital. We defined cases as complex sleeve pulmonary resections if they required pulmonary segment sleeve resection, extended sleeve resection (lobectomy plus segmentectomy of the remaining lobe), sleeve pneumonectomy, lobectomy plus carinoplasty or neo-carina construction, pulmonary-sparing main bronchus resection plus carina reconstruction, and distal trachea resection with end to end anastomosis.ResultsThe 20 cases comprised lung squamous cell carcinoma (n=11), lung adenocarcinoma (n=2), hamartoma (n=3), adenoid cystic carcinoma (n=2), carcinoid tumor (n=1), and pleomorphic carcinoma (n=1). The average blood loss during the operation was 250±126.17 mL (50–800 mL). The average operation time was 192.0±61.1 minutes. The average number of lymph node stations removed was 5.82±1.33, including station seven in all cases, and the median number of lymph nodes removed was 4.18±5.89. On the day of surgery, the drainage volume was 266±192.01 mL. The mean postoperative hospital stay was 5.37±1.86 days. Twelve of the 16 patients diagnosed with malignancy received postoperative chemotherapy. Granuloma formation at the anastomosis level led to stenosis in one case, and tumor recurrence occurred in one case. Broncho-esophageal fistula occurred in one patient after radiochemotherapy. The postoperative follow-up time was 15.6±10.7 months. The 30-day mortality was zero, and at one-year follow-up, only one patient had died of metastatic disease after the operation.ConclusionsUniportal video-assisted complex sleeve pulmonary resections are feasible when conducted by experienced teams.
