The aim of the study was to document the nature and incidence of surgical errors enacted during laparoscopic surgery in order to direct future research and surgical training. A modified Human Reliability Analysis (HRA) approach, based on direct observation, was adopted to categorise and record errors encountered during the practice of laparoscopic cholecystectomy. This study confirmed the applicability and usefulness of an observational methodology in the assessment of human error in endoscopic surgical performance. The study identified aspects of the design and usage of instruments, surgical training and the differences between tasks which needed further directed research in order to identify underlying performance shaping factors (PSFs) and so reduce error rates.
该研究的目的是记录腹腔镜手术过程中发生的手术失误的性质和发生率，以便指导未来的研究和外科培训。采用一种基于直接观察的改良人因可靠性分析（HRA）方法，对腹腔镜胆囊切除术实践中遇到的失误进行分类和记录。本研究证实了观察方法在评估内镜手术操作中的人为失误方面的适用性和实用性。该研究确定了器械的设计和使用、外科培训以及不同任务之间的差异等方面，需要进一步针对性研究，以识别潜在的绩效塑造因素（PSF），从而降低错误率。
