Abstract
Background
Previous ex vivo laparoscopic simulators have presented limitations in mimicking the thoracic and abdominal environment and lacked a teaching component. Therefore, we developed a complete organ laparoscopic training system (COLTS).
Methods
The COLTS consists of complete clusters of living organs representing abdomen and thorax, a training platform, a specific circulation solution, and a teaching module. Twelve experts assessed the COLTS in terms of its simulation of the surgical environment and intervention using a Likert scale questionnaire. Twelve residents were randomly assigned groups with or without the teaching module. Trainees assessed COLTS and underwent performance evaluations based on operating time, blood loss, adverse events, and economy of movement.
Results
Experts confirmed the ability of the COLTS to simulate the surgical environment and vessel pulse. All trainees positively evaluated the educational value of the COLTS. With the help of the teaching module, the trainees were more confident in the use of instruments (4.83 ± 0.41 vs. 3.83±0.98, p = 0.044) and positioning of trocars (4.67 ± 0.52 vs. 3.50 ± 0.84, p = 0.016) than were the trainees in the control group. Additionally, the teaching module group obtained better performance scores in terms of operation time (p = 0.008), reduced blood loss (p = 0.035), adverse events (p = 0.019), and economy of movement (p = 0.040), compared with the control group.
Conclusions
The COLTS is a useful and promising laparoscopic training system that simulates the thoracic and abdominal region. Furthermore, the teaching module can significantly improve the performance and participation of trainees.
期刊介绍:
The Journal of Surgical Education (JSE) is dedicated to advancing the field of surgical education through original research. The journal publishes research articles in all surgical disciplines on topics relative to the education of surgical students, residents, and fellows, as well as practicing surgeons. Our readers look to JSE for timely, innovative research findings from the international surgical education community. As the official journal of the Association of Program Directors in Surgery (APDS), JSE publishes the proceedings of the annual APDS meeting held during Surgery Education Week.
