Novel Pelvic and Retroperitoneal Anatomical Model for OBGYN Resident Education
Purpose: To create an anatomically accurate benchtop, low-cost
model to teach Obstetrics and Gynecology (OBGYN) residents pelvic and
Background: Medical simulation is a useful tool to help healthcare
providers practice procedures and identify anatomy. Our goal was to create a
low-cost, anatomically accurate pelvic model with anatomical structures
pertinent to gynecologic surgery.
Methods: The custom pelvic anatomy model was developed as a
clay moquette using anatomy textbooks for reference and included commonly
encountered anatomical features during gynecologic surgery. Volumetric
visualization of a pelvic CT was used to confirm anatomy. The final model was
created using 3D design software and 3D printed without didactic color. The
spaces, vessels, and nerves were tagged on the model for testing with
residents. The model was used to teach and help visualize pelvic and
retroperitoneal anatomy for OBGYN residents from PGY1 to PGY4. A survey was
given to 13 OBGYN residents before and after anatomy didactic.
Results: All residents (n=13) from PGY1 to PGY4 had zero to
limited procedural experience identifying retroperitoneal anatomy as a primary
surgeon. Residents’ ability to identify pelvic anatomy on the model increased
significantly post-lecture (p=< 0.001). Additionally, the resident’s
confidence with retroperitoneal pelvic anatomy increased (p=0.005). Residents
strongly agreed the model was accurate for intraperitoneal (mean 4.769/5) and
retroperitoneal anatomy (mean 4.769/5) and strongly agreed practice with the
model could improve technique (mean 4.7/5).
Discussions: The novel model shows promise in teaching residents to
identify pelvic and retroperitoneal anatomy without the cues of didactic color.
