Mastering laparoscopic suturing, a critical aspect of minimally invasive surgery, remains a challenge. Self-assessment and 'reflection before practice' may enhance the learning curve of laparoscopic suturing. This study investigates the optimal frequency of self-assessment and reflection before practice in laparoscopic suturing training.
Participants (medical students, surgical residents, and medical PhD students) underwent laparoscopic suturing training at home using a laparoscopic simulator (LaparoscopyBoxx). Three groups were formed: a 'control group' without self-assessment, a 'periodic self-assessment group', and a 'continuous self-assessment group'. The validated Laparoscopic Suturing Competency Assessment Tool (LS-CAT) served as self-assessment form. Participant's performance was quantified by objective parameters (time, distance, handedness, off-screen time, speed, acceleration, smoothness and distance between the instruments) measured by SurgTrac software.
No significant differences were observed between groups for primary outcome parameters time and distance across tests. However, significant differences emerged in secondary outcome parameters off-screen (baseline-test, p = 0.018), acceleration (baseline-test, p = 0.007), smoothness (baseline-test, p = 0.004; after-test, p = 0.038) and speed (after-test, p = 0.033) at various tests, favoring the self-assessment groups.
Self-assessment and reflection before practice may lead to more efficient instrument utilization and increased safety. A lower frequency of self-assessment and reflection before practice offered comparable benefits, which optimizes training efficiency, and is therefore recommended.
掌握腹腔镜缝合技术是微创手术的关键环节,但仍具挑战性。自我评估和“实践前反思”可能会优化腹腔镜缝合技术的学习曲线。本研究旨在探讨腹腔镜缝合训练中自我评估和实践前反思的最佳频率。
参与者(医学生、外科住院医师和医学博士生)使用腹腔镜模拟器(LaparoscopyBoxx)在家中进行腹腔镜缝合训练。分为三组:无自我评估的“对照组”、“定期自我评估组”和“持续自我评估组”。使用经过验证的腹腔镜缝合能力评估工具(LS-CAT)作为自我评估表。通过SurgTrac软件测量的客观参数(时间、距离、手的偏好、屏幕外时间、速度、加速度、平滑度和器械间距离)对参与者的表现进行量化。
在各项测试中,主要结局参数时间和距离在各组之间未观察到显著差异。然而,在次要结局参数屏幕外时间(基线-测试,p = 0.018)、加速度(基线-测试,p = 0.007)、平滑度(基线-测试,p = 0.004;测试后,p = 0.038)和速度(测试后,p = 0.033)方面,不同测试中出现了显著差异,自我评估组表现更佳。
实践前的自我评估和反思可能会提高器械使用效率并增加安全性。较低频率的实践前自我评估和反思也能带来类似益处,可优化训练效率,因此推荐采用。
