To support the improvement of advanced laparoscopic surgical procedures, we designed a quantitative analysis method to monitor surgical activities. The emphasis lies on the time spent on these activities and on the instruments controlled by the hands of the surgeon. Our method uses combined video images originating from the laparoscope, an overview CCD camera placed in the operating theatre and, when available, a video colonoscope. After the operation is finished, the images are evaluated by means of a standardised analysis routine based on a spreadsheet program and a set of standard terms (thesaurus), to minimise subjectivity of the analysis. After calculations, the data are presented in tables and graphs, resulting in objective information for research on the operation. Seven advanced laparoscopic procedures, in this case colon resections, have been analysed, and it was demonstrated that the analysis method is capable of describing different laparoscopic procedures using the limited thesaurus. Possible areas of application of the method are the evaluation of time-consuming parts of the operation, of surgical tasks and measurement of the surgeon's learning curve. Other applications are the prediction and measurement of the impact of new instruments and techniques.
为支持先进腹腔镜手术操作的改进，我们设计了一种定量分析方法来监测手术活动。重点在于这些活动所花费的时间以及外科医生手中控制的器械。我们的方法使用来自腹腔镜、放置在手术室的全景CCD摄像机以及（如有）视频结肠镜的组合视频图像。手术结束后，通过基于电子表格程序和一组标准术语（同义词库）的标准化分析程序对图像进行评估，以尽量减少分析的主观性。经过计算后，数据以表格和图表形式呈现，从而为手术研究提供客观信息。我们已经分析了七例先进的腹腔镜手术，在这种情况下是结肠切除术，结果表明该分析方法能够使用有限的同义词库描述不同的腹腔镜手术。该方法可能的应用领域包括评估手术中耗时的部分、外科手术任务以及测量外科医生的学习曲线。其他应用包括预测和测量新器械和技术的影响。
