Summary
A novel porcine model using liquid plastic effectively teaches laparoscopic partial nephrectomy (LPN) skills. Most participants found this surgical simulation enhanced their LPN learning experience.
Area of Science:
- Urology
- Surgical Education
- Medical Simulation
Background:
- Laparoscopic partial nephrectomy (LPN) is a complex surgical procedure.
- Transferring reconstructive skills for LPN is challenging.
- A need exists for effective training models for LPN.
Purpose of the Study:
- To develop and validate a porcine kidney model for teaching LPN.
- To assess the efficacy of this model in a surgical training course.
Main Methods:
- A tumor model was created in pig kidneys using percutaneous injection of liquid plastic.
- Five urologists initially evaluated the model.
- Twenty-eight participants in an advanced surgical course used the model for LPN training.
- Participant feedback was collected via questionnaires.
Main Results:
- The porcine tumor model was successfully created and maintained during LPN procedures.
- The model demonstrated realistic tumor characteristics visible and via ultrasonography.
- 96% of participants reported an enhanced learning experience with the model.
- Minor complications included hemostasis, ultrasonography, and instrumentation issues; two model-related complications occurred.
Conclusions:
- The Smooth-Cast liquid plastic model is an effective tool for surgical education in LPN.
- The model significantly improved the learning experience for most participating surgeons.
- Further refinement may address minor complications and enhance model reliability.
