Abstract: Objective To summarize the clinical experience of single - port thoracoscopic surgery in the treatment of pulmonary sequestration, and to evaluate the safety and effectiveness. Methods A total of 21 patients with pulmonary sequestration treated by single-port thoracoscopic surgery from January 2015 to May 2019 were retrospectively analyzed,including 10 males and 11 females, aged from 21 to 57 （39.5±9.2） years. The lesions of patients all located in the lower lung, including 13 cases in left lower lung and 8 cases in right lower lung. All cases were intrapulmonary sequestration except one were extrapulmonary sequestration. Lobectomy or segmental pulmonary resection was performed by thoracoscopy in 20 cases under general anesthesia with double lumen endotracheal intubation. One case was transferred to thoracotomy. Enhanced CT scan and 3D reconstruction were performed before operation. Results All operations were performed successfully, including 8 cases of severe adhesion of chest cavity. There were 20 patients underwent inferior lobectomy and 1 patient underwent posterior basal segment resection of the lower lung. The median operative time was （167.3±61.5） minutes, and the median intraoperative blood loss was （157.3±30.2） mL, the median postoperative catheter duration was （5.3±1.6） days, and the median postoperative hospital stay was （6.2±1.5） days. There were none death or serious complications occurred during the perioperative period. The follow-up time was 7~59 months, and there was no loss of follow-up. Reexamination of chest radiographs or CT showed no recurrence in all patients. Conclusion Single-port thoracoscopic surgery is safe and feasible in the treatment of pulmonary sequestration. Proper examination and assessment preoperative, and proper management of the abnormal vessel are the keys to successful operation.
