To summarize the application value and initial experience of CT-based 3D surgical model reconstruction technology(CT-3D surgical modeling technology) in pediatric robotic abdominal surgery.

For five pediatric patients from Oct. 2023 to Feb. 2025, we performed robotic surgery following the construction of surgical models and preoperative simulation via CT-3D surgical modeling technology. Among the surgeries, there was one case of robotic-assisted hepatic resection for hepatoblastoma; one case of robotic-assisted emergency surgery, including duodenal repair, central pancreatectomy, and pancreatic body-jejunal anastomosis; one case of robotic-assisted pancreaticoduodenectomy (Whipple procedure); one case of robotic-assisted intra-abdominal lymphangioma resection; and one case of robotic-assisted retroperitoneal lymphangioma resection. Subsequently, we summarized the application value and our initial experience of CT-3D surgical modeling technology in pediatric robotic abdominal surgery for complex anatomies.

A total of five patients (three males and two females) aged 10.0±2.45 years underwent the procedure. The mean surgical time was 475.6±280.03 minutes, and intraoperative bleeding: median 50 ml (range 10-300). These surgical models accurately reflected the intraoperative anatomy, and preoperative simulation with them reduced unnecessary intraoperative manipulations and significantly improved surgical efficiency.

CT-3D surgical modeling technology enhances the predictability of robotic surgical steps and holds positive implications for broadening the indications for pediatric robotic abdominal surgery.
