The Complete Organ Laparoscopic Training System (COLTS) effectively simulates the surgical environment for training. Incorporating a teaching module significantly enhances trainee confidence and surgical performance.
Area of Science:
- Surgical Simulation
- Medical Education Technology
- Laparoscopic Surgery Training
Background:
- Existing ex vivo laparoscopic simulators have limitations in replicating thoracic and abdominal environments.
- These simulators often lack integrated teaching components, hindering comprehensive skill development.
Purpose of the Study:
- To introduce the Complete Organ Laparoscopic Training System (COLTS), a novel simulation system.
- To evaluate the effectiveness of COLTS in simulating the surgical environment and assess the impact of an integrated teaching module on trainee performance.
Main Methods:
- COLTS comprises living organ clusters, a training platform, circulation solution, and a teaching module.
- Experts assessed COLTS realism; residents were divided into groups with or without the teaching module for performance evaluation.
- Performance metrics included operating time, blood loss, adverse events, and economy of movement.
Main Results:
- Experts validated COLTS's ability to simulate the surgical environment and vessel pulse.
- Trainees with the teaching module showed increased confidence in instrument use and trocar positioning.
- The teaching module group demonstrated significantly improved performance in operation time, blood loss, adverse events, and economy of movement.
Conclusions:
- COLTS provides a realistic simulation of the thoracic and abdominal regions for laparoscopic training.
- The integrated teaching module demonstrably enhances trainee performance and engagement in laparoscopic surgery.
