20 cases of robotic assisted thoracoscopic surgery for the treatment of pulmonary sequestration in children / 中华胸心血管外科杂志

ABSTRACT

Objective:To analyze the application of robot-assisted thoracoscopic surgery in the treatment of pulmonary sequestration in children.Methods:The clinical data of 20 children with pulmonary sequestration admitted to the Children's Hospital Zhejiang University School of Medicine from May to November 2020 were analyzed retrospectively. There were 13 males and 7 females, ages ranged from 6 months to 5 years old, with median age of 10 months. Body weight ranged from 7.5 to 18.0 kg, with mean weight of(9.95±2.46)kg. Abnormal blood supply vessels in pulmonary sequestration were found by chest enhanced CT and were further confirmed during surgery. All the other 19 cases were found to have pulmonary lesions by prenatal ultrasound except 1 case due to repeated infection. The lesions were located in left lung in 15 cases and right lung in 5 cases.Results:1 case was converted to thoracotomy due to failure of intraoperative single lung ventilation and inability of artificial pneumothorax to collapse the lung lobe, and other 19 cases were successfully completed by robot-assisted thoracoscopic surgery. The operation time ranged from 40 to 270 min, mean(88.25±55.68) min. All 10 patients with extralobar sequestration underwent simple pneumonectomy, including 2 patients with intra-diaphragmatic pulmonary sequestration. In 10 cases of intralobar sequestration, 2 cases underwent wedge resection, 2 cases underwent segmental resection, and 6 cases underwent lobectomy. No operative death occurred. The postoperative hospital time ranged from 3 to 10 days, mean(5.00±1.89) days. All patients recovered well and no complications such as pleural effusion and atelectasis were observed during 1-6 months follow-up.Conclusion:The robotic surgical system is safe and effective for the treatment of pulmonary sequestration in children.
