Obliterated Posterior Cul-de-sac Laparoscopic Surgical Simulation

Area of Science:

• Surgical Education
• Minimally Invasive Surgery
• Gynecologic Surgery

Background:

• Obliteration of the posterior cul-de-sac presents a significant surgical challenge during gynecologic procedures.
• Laparoscopic dissection skills for this finding are crucial but training exposure is inconsistent.
• A need exists for effective simulation models to teach this technique.

Purpose of the Study:

• To design a low-cost, high-fidelity laparoscopic simulation model for the posterior cul-de-sac.
• To provide a training tool emphasizing skills for laparoscopic dissection of an obliterated cul-de-sac.

Main Methods:

• A novel three-dimensional simulation model was developed.
• Nine experts and 17 residents participated in a 30-minute simulation session.
• Face validity was assessed through participant feedback and blinded video grading.

Main Results:

• The simulation model was rated as highly realistic and useful by both experts and residents.
• Residents demonstrated a statistically significant increase in comfort with the dissection technique.
• Experts outperformed residents in blinded video assessments, indicating model effectiveness.

Conclusions:

• This low-cost, reproducible simulation model addresses a critical gap in gynecologic surgical education.
• The model enhances trainee confidence and proficiency in managing obliterated posterior cul-de-sacs.
• It serves as a valuable tool for improving surgical outcomes in procedures like hysterectomy and ovarian surgery.
