Northwestern MedicineA 3D Simulation Retroperitoneal Dissection Model to Improve Training

Northwestern Medicine researchers have developed an innovative 3D low-fidelity retroperitoneal dissection model to enhance surgical training for complex gynecologic procedures. The model addresses the need for accessible, cost-effective training solutions while maintaining anatomical accuracy through 3D-printed structures and realistic tissue simulation. This development represents a significant step forward in surgical education, particularly for procedures involving endometriosis and large fibroid pathology.

Key Points:

• The model focuses on advanced laparoscopic surgical skills, specifically designed for retroperitoneal dissection, uterine artery ligation, and ureter dissection – critical techniques required for managing complex pathologies with higher bleeding risks.
• Materials include 3D-printed blood vessels and ureters covered by a lifelike peritoneal layer, providing accurate anatomical relationships and tactile feedback within a bowl-like structure that mimics the bony pelvis.
• Development involved multiple phases, including needs assessment, prototype design in collaboration with Northwestern’s Innovations Lab, and validation through a pilot study with attending gynecologic surgeons and fellows.
• The simulation model enables repetitive practice of delicate surgical techniques without ethical considerations or patient risk, making it particularly valuable for training in high-stakes procedures.
• Pilot study feedback confirmed the model’s accuracy and educational value while identifying areas for improvement in tactile feedback and material properties.

“As a surgeon and an educator, it allows me to promote patient safety and better patient outcomes by enabling our learners to develop these advanced skills that they ordinarily wouldn’t be able to do without access to simulation environments like this.”
