Robotic-Assisted Patent Ductus Arteriosus Ligation in Children.

BACKGROUND

There is limited experience of robotic-assisted surgery for patent ductus arteriosus (PDA) treatment in children. In the present study, we update the experience of robotic PDA ligation in a larger number of pediatric populations.

METHODS

From August 2020 to March 2025, 425 children with PDA who underwent robot-assisted thoracoscopic surgery were enrolled in Children's Hospital of Zhejiang University School of Medicine. The patients' demographic data together with their perioperative clinical variables were retrospectively analyzed.

RESULTS

The average age of the patients was 34.2 ± 26.2 months which ranged from 6 months to 13 years with a median age of 24 months. The average weight was 14.8 ± 7.1 kg (kg) which ranged from 6 kg to 66 kg with a median weight of 13.2 kg. There were 160 (37.6 %) boys and 265 (62.4 %) girls respectively. In addition, the PDA diameter was between 0.2 cm (cm) and 0.8 cm, with a median diameter of 0.3 cm (average was 0.38 ± 0.25 cm). The robot system operation surgery time ranged from 12 min (min) to 90 min, with a median 26 min (average was 45.6 ± 31.9 min). The length of hospital stay ranged from 1 day to 5 days over all. Notably, 263 patients (61.9 % in all patients) underwent day surgery management.

CONCLUSIONS

Robotic assisted surgery for PDA ligation in children older than 6 months old is safe and effective procedure with good prospects. As a minimally invasive approach, it should be considered as an option for PDA treatment in children with age older than 6 months.
