研究目的:

本研究通过人工智能(AI)辅助预测结肠镜进镜方向,完善对于进镜过程的质量监控,使结肠镜更安全有效的到达回肠末端,并且针对操作经验不足的青年内镜医师有效地构建结肠镜操作学习曲线。  

Objectives of Study:

By employing artificial intelligence (AI) to assist in predicting the direction of colonoscope advancement, this study enhances the quality monitoring of the insertion process. This approach facilitates safer and more effective passage of the colonoscope to the terminal ileum and supports the development of operational proficiency among young endoscopists with limited experience.

随机方法(请说明由何人用什么方法产生随机序列):

非随机对照研究,患者分组方法为:本研究为前瞻性队列研究。根据患者和操作医师共同做出的临床决策,将入组患者分为两组:AI辅助组(接受AI辅助进镜组)和对照组(常规进镜组)。为增强组间的可比性,我们将采用倾向评分匹配(PSM) 的方法,根据年龄、性别、BMI等基线变量来控制混杂因素的影响。

Randomization Procedure (please state who generates the random number sequence and by what method):

This was a non-randomized controlled, prospective cohort study. Patients were divided into two groups based on clinical decisions made jointly by the patient and the operating physician: the AI-assisted group (underwent AI-assisted colonoscope insertion) and the control group (underwent conventional colonoscope insertion). To enhance comparability between the groups, Propensity Score Matching (PSM) was employed to control for the effects of confounding factors based on baseline variables such as age, gender, and BMI.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

在结果评估和数据分析阶段实施盲法:本研究无法对患者和操作医师设盲。然而,为减少测量偏倚,我们对结局事件的判定医师和数据统计分析师实施了设盲。结局判定的专家在审阅病例资料时,不会知晓患者所属的分组。数据分析师将收到一组匿名的、用代码(如Group 1和Group 2)表示的数据,直至所有统计分析完成后才揭晓代码对应的实际分组。

Blinding:

Blinding of patients and operating physicians was not possible due to the nature of the intervention. However, to reduce measurement bias, blinding was implemented for the physicians assessing the outcomes and the data statisticians. Specifically, the experts determining the outcomes were blinded to patient group allocation when reviewing case materials. The data analyst received an anonymized dataset labeled with codes (e.g., Group 1 and Group 2), and the actual group assignments corresponding to these codes were not revealed until all statistical analyses were completed.

IPD sharing

是Yes

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

试验结束后,预计2026年12月份进行相关论文的投稿,原始数据会上传ResMan(http://www.medresman.org.cn/)或国家生物信息中心 (https://ngdc.cncb.ac.cn/gsub/)等网站

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Planned manuscript submission is scheduled for December 2026 following trial completion. All raw data will be uploaded to public repositories like ResMan (http://www.medresman.org.cn/) or China's National Genomics Data Center (NGDC, https://ngdc.cncb.ac.cn/gsub/).

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:

患者一般资料由科研人员建立档案进行记录,该档案对外保密,只有研究小组成员有权进行查阅,内镜特征及病理结果通过美迪康内镜临床研究数据管理与报告系统采集,研究过程中由计算机与助手协助记录进镜时间等相关结局指标,后交由研究小组中数据分析者进行统计分析。所有数据均采用去标识化处理,研究团队无法识别个体患者信息,隐私泄露风险极低。研究者将立即为每位受试者生成一个唯一的研究识别码(Study ID),所有包含个人身份标识的信息(如姓名、身份证号、电话号码、住院号等)将被完全删除或替换为该Study ID。

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

General Patient Data: Research personnel created confidential records for general patient data, accessible only to study team members. Endoscopic Characteristics and Pathological Results: These were collected via the Medicon Endoscopic Clinical Research Data Management and Reporting System. Outcome Indicator Recording: Outcome indicators such as insertion time during the study were recorded with the assistance of computer systems and research assistants, and were subsequently handed over to the data analyst within the research team for statistical analysis. Privacy Protection: All data were de-identified. The research team immediately generated a unique Study ID for each participant. All personally identifiable information (such as name, ID number, phone number, hospital admission number, etc.) was completely removed or replaced with this Study ID. Consequently, the research team could not identify individual patient information, resulting in a very low risk of privacy breach.
