Novel 3D Custom-Made Silicone Tumor Model as a Support for Teaching Surgical Oncology Principles

Area of Science:

• Veterinary Medicine
• Medical Education
• Surgical Oncology

Background:

• Traditional animal-based surgical labs raise ethical concerns.
• Cadaveric models have limitations in pathology and availability.
• Need for effective, alternative surgical training methods in veterinary education.

Purpose of the Study:

• To develop and evaluate a novel 3D-printed silicone soft tissue tumor model for veterinary surgical training.
• To assess the model's efficacy in teaching surgical oncology principles and techniques.
• To determine the face and content validity of the model.

Main Methods:

• 3D-printed molds from canine soft tissue sarcoma CT images created a custom silicone tumor model.
• Veterinary students and professionals utilized the model for simulated surgical procedures.
• Qualitative surveys and Likert-style questionnaires assessed model validity and user experience.

Main Results:

• All participants successfully completed practical training using the 3D tumor model.
• The model facilitated error identification and understanding of clinical impacts in biopsy and excision.
• High average scores for face (3.8/5) and content validity (4.6/5 instructors, 4.4/5 students) were achieved.

Conclusions:

• The 3D-printed silicone tumor model is an effective, non-cadaveric alternative for veterinary surgical education.
• This novel teaching tool can improve surgical skill acquisition and error recognition.
• The model holds significant potential as a valuable resource in veterinary curricula.
