研究目的:

根据直肠乙状结肠移行部体表定位,通过适时腹部按压,发现有效防止直肠乙状结肠移行部伸展、避免乙状结肠结襻的腹部压迫点,探索单人操作结肠镜无襻进镜抵达盲肠的规律。  

Objectives of Study:

Based on the surface localization of the rectosigmoid junction, timed abdominal compression was applied to identify effective abdominal pressure points that prevent the Stretching of the rectosigmoid junction and avoid sigmoid colon looping. This study explores the underlying principles for achieving cecal intubation using single-operator colonoscopy with loop-free insertion.

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:

(1)数据收集与录入:本研究所有患者信息和结肠镜操作数据均通过专用病例报告表(CRF)实时记录,包括患者基本信息、既往手术史、体型、年龄、性别、肠镜类型、无袢无伸展进镜情况及腹部按压使用情况等。所有数据在采集时由内镜医师及研究助理现场确认,确保准确、完整。 (2)数据存档与管理:研究数据将统一录入加密电子数据库,设立双重录入和逻辑校验机制,减少录入错误。原始纸质资料妥善保存在专用档案柜中,仅限研究团队成员查阅。电子数据定期备份至安全服务器,确保数据安全性和可追溯性。 (3)样本管理:无样本。 (4)统计分析:所有数据分析由独立统计师完成,使用标准统计软件(如SPSS 24.0)进行。主分析包括各组无袢无伸展进镜成功率比较、暴露因素相关分析及亚组探索性分析。统计分析过程中,将严格遵循预设分析计划,避免选择性报告。 (5)质量控制:内镜操作及数据记录均遵循标准化操作流程,确保一致性。研究团队定期召开质控会议,审查数据完整性和准确性,发现问题及时纠正。对关键变量(如进镜成功率、腹部按压记录)进行随机抽查复核,保证数据可靠性。 (6)监查与稽查:本研究为观察性前瞻性队列研究,不涉及药物或高风险干预,因此不设独立外部监查;研究团队内部定期进行自查,确保各项操作符合研究方案及伦理规范。

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

(1) Data collection and entry: All patient information and colonoscopy operation data in this study were recorded in real time through a dedicated case report form (CRF), including basic patient information, previous surgical history, body type, age, gender, colonoscopy type, no-loop and no-extension insertion situation, and abdominal compression usage, etc. All data were confirmed on-site by the endoscopist and research assistant during collection to ensure accuracy and completeness. (2) Data archiving and management: The research data will be uniformly entered into an encrypted electronic database, with a dual entry and logical verification mechanism to reduce entry errors. The original paper materials are properly stored in dedicated filing cabinets and are accessible only to the research team members. Electronic data are regularly backed up to a secure server to ensure data security and traceability. (3) Sample management: No samples. (4) Statistical analysis: All data analysis was completed by an independent statistician using standard statistical software (such as SPSS 24.0). The main analysis included comparisons of no-loop and no-extension insertion success rates in each group, analysis of exposure factors, and exploratory analysis of subgroups. During the statistical analysis process, the preset analysis plan will be strictly followed to avoid selective reporting. (5) Quality control: Endoscopic operations and data recording follow standardized operating procedures to ensure consistency. The research team holds regular quality control meetings to review the completeness and accuracy of the data, and promptly correct any problems. Random checks and re-examinations of key variables (such as insertion success rate, abdominal compression records) are conducted to ensure data reliability. (6) Monitoring and auditing: This study is an observational prospective cohort study and does not involve drugs or high-risk interventions, so there is no independent external monitoring. The research team conducts regular self-inspections to ensure that all operations comply with the research protocol and ethical guidelines.
