Canine Upper Digestive Tract 3D Model: Assessing Its Utility for Anatomy and Upper Endoscopy Learning

Area of Science:

• Veterinary Anatomy Education
• Medical Simulation Technology

Background:

• Traditional teaching methods for canine upper digestive tract (UDT) anatomy and endoscopy can be limited.
• The use of 3D-printed models offers a novel approach to anatomical visualization and procedural training.

Purpose of the Study:

• To evaluate the effectiveness of 3D-printed canine UDT models in anatomy demonstration and endoscopy instruction.
• To compare student perceptions of 3D models versus traditional specimens.

Main Methods:

• 3D models of the canine UDT (esophagus-stomach-duodenum) were created using silicone casting from scanned data.
• First-year students used models for anatomy, while fifth-year students used them for endoscopy training.
• Anonymous surveys assessed student feedback on model effectiveness.

Main Results:

• Both first-year (n=93) and fifth-year (n=45) students found the 3D models effective for learning.
• First-year students reported improved understanding of size, volume, and topography.
• Fifth-year students valued the models for spatial vision and clinical training.

Conclusions:

• 3D-printed canine UDT models are effective tools for hands-on clinical endoscopy training.
• These models serve as valuable complementary resources for teaching anatomy and topography.
• While not a replacement for natural specimens, 3D models enhance veterinary education.
