Brief Summary
Effective preoperative planning and real-time intraoperative guidance are crucial for performing accurate liver resections. To address this need, the researchers have designed advanced 3D-printed liver models using a self-healing elastomer, created through the copolymerization of 4-acryloylmorpholine (ACMO) and methoxy poly(ethylene glycol) acrylate (mPEGA). These models demonstrate outstanding healing properties, swiftly restoring their structure within minutes at room temperature, and quickly recovering after incisions. In previous studies, Professor Yuhua Zhang, the project applicant, collaborated with a team from Zhejiang University to develop a 3D-printed liver model that is self-healing and reusable for repeated cutting. They preliminarily explored the feasibility of applying this model for preoperative planning and surgical training for liver surgeries. The results were published in Nature Communications (Lu et al., Nat Commun. Dec 19;14(1):8447). Building on this, the applicant intends to establish a personalized liver surgery planning system (Personalized Liver Surgery Planning System Based on High-Fidelity 3D Printed Self-Healing Liver Models, SH-LPS), which will assess, through a randomized controlled trial, the value of SH-LPS in improving liver surgery efficiency and safety.

Study Arms (2)
3D group
EXPERIMENTALA three-dimensional digital model is constructed based on the patient's CT/MRI data and a physical model is printed. Using the model's self-healing property after cutting, multiple simulated surgeries are performed to help plan the optimal surgical approach. The best surgical path derived from the model is combined with traditional CT/MRI data to determine the final surgical path, and the surgery is then performed according to this finalized path.
CT/MRI group
SHAM COMPARATORThe surgical approach is planned based on traditional two-dimensional CT/MRI images, and the surgery is performed according to this planned path.
Interventions
A three-dimensional digital model is constructed based on the patient's preoperative CT/MRI images, and a personalized physical model is created using 3D printing. This model has the ability to self-heal after being cut. Surgeons can perform multiple simulated surgeries on the model to plan the optimal surgical path before the authetic surgery
Obtain the patient's CT/MRI images and determine the definitive surgical path based on the two-dimensional images.
