To evaluate the efficacy and safety of Da Vinci robot assisted endoscopic technique in the treatment of patent ductus arteriosus (PDA) in children.

From August 2020 to March 2021, clinical data were retrospectively reviewed for 35 PDA children undergoing Da Vinci robot assisted endoscopy.Age, weight, diameter of ductus arteriosus, operative duration, postoperative hospital stay, postoperative complications and operative cost were recorded.During operations with right supine 90 degrees position, one observation hole and two operation holes were placed in Ⅴ intercostal space of axillary midline, Ⅳ intercostal space of axillary front line and Ⅵ intercostal space of subscapular line.And one auxiliary hole was placed in Ⅶ intercostal space of anterior axillary line.PDA was ligated by silk Ⅶ thread with double or three folds during operation.Then they were withdrawn from a ventilator and returned to general ward.

All procedures were completed with the assistance of robot.There was no intraoperative conversion into thoracotomy.The average operative duration was 50.5(20-84) min.There was no obvious intraoperative hemorrhage.The average postoperative hospital stay was 1.8(1-6) days.There was one case of residual ductus arteriosus.And another case of recurrent laryngeal nerve injury improved after 3-month follow-ups.The average cost of hospitalization was 54, 000 yuan RMB.No other immediate complications occurred during a follow-up period of 1-6 months.

Da Vinci robotic surgery for pediatric PDA is safe, effective and reliable with minimal trauma, faster recovery and fewer surgical risks.
