Use of Simulation For Training Advanced Colorectal Procedures

Area of Science:

• Minimally invasive surgery
• Surgical simulation
• Colorectal surgery training

Background:

• Minimally invasive colorectal procedures require specialized training.
• Simulation is an emerging tool for surgical education.
• Assessing simulation's impact on resident learning is crucial.

Purpose of the Study:

• To evaluate the effect of simulation on procedural knowledge.
• To assess the impact of simulation on simulated surgical performance.
• To analyze resident confidence and skill acquisition in laparoscopic low anterior resection (LLAR) and robotic right colectomy (RRC).

Main Methods:

• Simulation models were developed using human cadavers for LLAR and RRC.
• Resident knowledge and confidence were self-assessed pre- and post-simulation.
• Faculty used validated scales (OSATS-GRS, GEARS) to evaluate performance.
• Statistical analyses included paired t-tests, correlation, and descriptive statistics.

Main Results:

• Procedural knowledge scores significantly increased for both LLAR and RRC.
• Resident confidence in performing LLAR and RRC improved significantly.
• Higher scores on OSATS GRS correlated with prior laparoscopic colorectal experience.
• Knowledge gains were most significant in the PGY4 resident cohort.

Conclusions:

• Simulation training enhances procedural knowledge and resident confidence.
• This simulation method serves as a safe adjunct to live surgical experience.
• Future simulations will focus on earlier learning curves and integrate with operative assessments.
