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.
完整的器官腹腔镜训练系统:一种新颖的离体腹腔镜模拟器。
背景:以前的体外腹腔镜模拟器在模拟胸部和腹部环境方面存在局限性,并且缺乏教学成分。因此,我们开发了一个完整的器官腹腔镜训练系统(COLTS)。方法:COLTS由代表腹、胸的完整活体器官群、训练平台、特定循环溶液和教学模块组成。12位专家使用李克特量表问卷评估COLTS对手术环境和干预的模拟。12名住院医生被随机分配到有或没有教学模块的小组。受训人员对COLTS进行评估,并根据手术时间、出血量、不良事件和运动经济性进行绩效评估。结果:专家证实了COLTS模拟手术环境和血管脉搏的能力。所有学员都积极评价COLTS的教育价值。在教学模块的帮助下,学员对仪器的使用更有信心(4.83±0.41 vs。(3.83±0.98,p = 0.044)和套管针定位(4.67±0.52 vs. (0.05);(3.50±0.84,p = 0.016)。此外,教学模块组在手术时间(p = 0.008)、出血量(p = 0.035)、不良事件(p = 0.019)、运动经济性(p = 0.040)方面均优于对照组。结论:COLTS是一种实用且有发展前景的模拟胸腹区域的腹腔镜训练系统。此外,教学模块可以显著提高学员的绩效和参与度。

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.
