Insights
Robotic surgery for patent ductus arteriosus (PDA) in children over six months is safe and effective. This minimally invasive approach offers good prospects for treating PDA in pediatric patients.
Area of Science:
- Pediatric Surgery
- Minimally Invasive Techniques
- Cardiovascular Surgery
Background:
- Limited experience exists for robotic-assisted surgery in pediatric patent ductus arteriosus (PDA) treatment.
- This study updates the experience with robotic PDA ligation in a larger pediatric cohort.
Purpose of the Study:
- To evaluate the safety and efficacy of robotic-assisted thoracoscopic surgery for PDA ligation in children.
- To assess the feasibility of robotic PDA treatment in a pediatric population.
Main Methods:
- Retrospective analysis of 425 children with PDA who underwent robot-assisted thoracoscopic surgery from August 2020 to March 2025.
- Data collected included demographic and perioperative clinical variables.
Main Results:
- The study included children aged 6 months to 13 years, with an average age of 34.2 months.
- Surgical times ranged from 12 to 90 minutes (median 26 min).
- A significant portion (61.9%) of patients were managed with day surgery.
Conclusions:
- Robotic-assisted surgery for PDA ligation in children over six months old is a safe and effective procedure.
- This minimally invasive approach presents a promising option for pediatric PDA treatment.
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.
