Background: To explore the clinical application of robotic-assisted surgery in paediatric solid tumours and to explore its feasibility.Methods: From 2015 to 2022, 53 children with solid tumours underwent roboticassisted surgery in our centre were retrospectively analysed.
Results:The mean weight of the patients was 27.7 kg, and the mean age was 6.7 years. The average tumour volume was 5.5*4.6*3.7 cm. Two procedures (3.8%) were converted. The mean total operative time was 198.5 min. The mean estimated blood loss was 27.1 ml, and no intraoperative complications occurred. Two (3.8%) patients had postoperative complications. At a median follow-up of 21.2 months, one (1.9%) patient with malignant tumours stopped treatment, and two (3.8%) patients developed tumour recurrence.Conclusions: Robotic-assisted tumour resection is feasible in highly selected cases of young age, light weight, huge tumour or malignant tumour.

Robotic-assisted surgery has been used in children in recent years, and many studies have shown its potential advantages of this surgery for patients compared to conventional minimally invasive surgery. Robotic-assisted surgery has also been introduced in the treatment of paediatric solid tumours. 1-3 In 2002, Gutt et al. reported early experiences of robotic-assisted surgery in a child with gonadoblastoma. 4 Cundy et al. published a systematic review of robot-assisted minimally invasive surgery for paediatric solid tumours in 2014. 5 Meignan et al. reported a retrospective analysis of robotic-assisted surgery for paediatric tumours in 2017. 6The current robotic surgery system is designed for adults; moreover, paediatric tumour resection must also abide by oncology principles such as complete tumour resection, the complete removal of tumour specimens and the avoidance of tumour metastasis and dissemination. Some scholars believe that robotic-assisted surgery is risky for children who are young, have a low weight, or have large tumours. In summary, the use of robotic-assisted surgery is limited due to the constraints of tumour surgery principles, age, weight, tumour size, etc. Consequently, the progress of minimally invasive surgery and robotic-assisted surgery for malignant solid tumours in children is proceeding slowly, and there are currently no adequate studies on robotic-assisted surgery in the treatment of paediatric solid tumours.Since the da Vinci robotic surgery system was introduced to our centre in 2015, we have performed robotic-assisted surgery in the treatment of congenital diseases such as choledochal cysts and Hirschsprung's disease, and we performed the first robotic-assisted thoracoscopic mediastinal tumour resection in mainland China in June 2015. As of August 2022, robot-assisted surgery has been completed for 53 paediatric solid tumours in our centre, and the objective of this study was to present our experi...
