This study developed an affordable laparoscopic camera navigation (LCN) simulator and curriculum. Training on the simulator significantly improved surgical skills and view optimization in medical students.

Area of Science:

Medical Simulation
Surgical Education
Laparoscopic Surgery

Background:

Laparoscopic camera navigation (LCN) is crucial for laparoscopic surgery but lacks sufficient training.
Developing cost-effective training tools is essential for surgical education.

Purpose of the Study:

To develop an inexpensive LCN simulator and structured curriculum.
To assess the transferability of skills acquired through simulator training to a porcine model.

Main Methods:

Developed 0- and 30-degree LCN simulators for a videotrainer platform.
A randomized controlled trial with 20 medical students assessed skill transferability.
Performance was evaluated using verbal cues, percentage of optimal surgical view (%OSV), and procedure time.

Main Results:

The LCN simulator was inexpensive ($25/board) and durable, requiring 35 man-hours to develop.
The trained group showed significant improvements in verbal cues, %OSV, and procedure time compared to the control group.
Posttesting revealed significantly better verbal cue scores and %OSV in the trained group.

Conclusions:

The developed LCN simulator is a cost-effective tool for surgical training.
Skills acquired using the simulator effectively translate to improved performance in a simulated operating room environment.
