研究目的:

开发一种基于AI的结直肠息肉诊断辅助系统,能够通过术中动态视频自动判断息肉的良恶性,并提高结直肠癌的早期筛查效果。具体目标包括: 构建高质量的术中动态视频数据集:收集来自多个医疗中心的结直肠息肉术中视频数据,并进行详尽的标注工作,为AI模型的训练提供足够的样本和标注信息。该数据集将包括不同形态、大小、位置的息肉,以及这些息肉的良恶性标签。 开发并验证AI模型的精确度和临床适应性:开发能够从术中动态视频中提取病变信息的AI模型,并在临床中验证其准确性。特别是在动态视频分析的背景下,利用时序建模技术提升对病灶的理解和判断能力,力求提高AI诊断的准确率、灵敏度和特异性。 评估AI系统对诊断效率和一致性的影响:通过与内镜医生的诊断结果对比,评估AI系统在实际操作中的表现,分析其对医生诊断效率和一致性的提升,特别是在多中心、多病例场景下的效果。 建立AI辅助诊断的临床标准与指南:根据研究结果,制定AI辅助诊断系统的应用指南,帮助医生有效利用该系统进行息肉的早期筛查与评估。同时,将该技术推广至基层医院,推动AI在结直肠癌筛查中的应用。  

Objectives of Study:

To develop an AI-based colorectal polyp diagnosis assistant system, which can automatically determine the benign and malignant of polyps through intraoperative dynamic video, and improve the early screening effect of colorectal cancer. Targets include: Construction of a high-quality intraoperative dynamic video dataset: the intraoperative video data of colorectal polyps from multiple medical centers were collected and annotated in detail to provide sufficient samples and annotation information for the training of AI models. This dataset will include polyps of different shapes, sizes, locations, and the benign and malignant signatures of these polyps. Develop and validate AI models for accuracy and clinical adaptation: Develop an AI model that can extract lesion information from intraoperative dynamic videos, and validate its accuracy in the clinic. Especially in the context of dynamic video analysis, time series modeling technology is used to improve the understanding and judgment ability of lesions, and strive to improve the accuracy, sensitivity and specificity of AI diagnosis. To evaluate the effect of the AI system on the diagnostic efficiency and consistency: By comparing the diagnostic results of the AI system with those of the endoscopists, the performance of the AI system in actual operation was evaluated, and the improvement of the diagnostic efficiency and consistency of the doctors was analyzed, especially in the multi-center and multi-case scenario.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据采集:通过CRF表格采集患者信息。 数据管理:为每一位签署知情同意书的患者分配一个唯一的、不重复的研究编号。所有采集的数据(eCRF、视频文件)均仅使用此研究编号进行标识,严格去除患者姓名、身份证号、住院号、电话号码、住址等个人身份信息。创建并严格保管一个独立的“研究编号-患者身份信息”的关联文件。该文件必须加密存储,访问权限仅限于极少数核心研究人员。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection: Patient information was collected through a CRF form. Data management: A unique, non-duplicate study number was assigned to each patient who signed an informed consent form. All collected data (eCRF, video files) were identified only with this study number, and personal identity information such as patient name, identification number, hospitalization number, telephone number, and address were strictly removed. Create and maintain a separate "Study Number-Patient Identification" linkage file. The file must be stored encrypted, and access is limited to a very small number of core researchers.
