随机方法(请说明由何人用什么方法产生随机序列):

本研究采用简单随机化方法生成随机序列,不进行分层。 随机序列由统计师使用R语言的Blockrand包运行生成,将符合入组标准的所有受试者按 1:1比例随机分配至干预组或对照组。 为保证两组病例数均衡,采用区组随机化设计,区组长度设为6(即每6例受试者为一个区组,内部分配3例至干预组、3例至对照组),区组长度对研究团队设盲。

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

The study used a simple randomization method to generate a random sequence without stratification. The random sequence was generated by a statistician using the R language' "Blockrand" package, assigning all subjects who met the inclusion criteria to the intervention group or the control group at a 1:1 ratio. To ensure a balanced of cases in both groups, a block randomization design was used, with the block length set to 6 (i.e., every 6 subjects formed a block, with3 subjects assigned to the intervention group and 3 subjects to the control group within each block), and the block length was blinded to the research team

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:

本研究将采用专门为本研究自主开发的网站系统进行电子数据采集与管理。所有结局指标、基线数据及其他试验数据将通过电子病例报告表(eCRF)的形式在该系统中进行记录和评估。 (1)数据收集计划:a.基线数据:在患者入组时,于系统中录入人口统计学信息、疾病史、肿瘤临床分期(基于影像学)、术前实验室检查结果、ASA分级、肛门功能评分(Wexner, LARS)及生活质量评分(EORTC QLQ-C30)。b.术中数据:在手术结束后72小时内,由参与手术的研究者录入手术时间、出血量、输液量、尿量、手术方式、吻合情况等。c.术后住院数据:每日记录患者恢复情况,包括疼痛VAS评分、首次下床活动时间、首次排气时间、首次进食时间等,直至出院。并发症情况将实时记录。d.随访数据:在预设的随访时间点(术后第12个月、1/3/6//12/个月),由指定研究者根据门诊复查、影像学报告、实验室检查及问卷结果,在系统中完成相应的eCRF模块,内容包括并发症评估(Clavien-Dindo分级)、肛门功能评分、生活质量评分。 (2)录入工具的可靠性:自主开发网站将部署在安全的云服务器或医院内部服务器上,确保高可用性和持续稳定运行。系统将提供定期数据备份与灾难恢复机制,以保障数据安全。 (3)数据准确性保障:a.界面设计:eCRF界面设计将模拟研究流程,逻辑清晰,减少录入错误。b.预设逻辑校验:系统内嵌实时逻辑核查功能,对录入数据进行即时验证。例如,对数值范围(如年龄18-75岁)、日期逻辑(随访日期不早于手术日期)、必填字段等进行强制校验,对异常值或逻辑冲突数据发出提示,阻止不合规数据提交。c.标准术语编码:对分类变量(如肿瘤分期、并发症类型)采用标准化下拉菜单选择,避免自由文本输入带来的歧义和不一致性。 本研究的电子数据管理将遵循ALCOA+原则(可归因、易读、同时、原始、准确、完整、一致、持久、可用),并实施以下方案以确保数据质量、保密及安全: (1)数据录入与编码:a.权限控制:研究人员将获得专属账号与密码。系统将记录所有用户操作日志,确保数据操作的“可归因性”。b.数据编码:所有受试者将以唯一研究编号进行标识,eCRF中不直接记录患者姓名、身份证号等个人敏感信息。分类变量在录入时即采用预设编码,确保数据标准化。 (2)数据质量控制措施:a.双重录入与核查:对于所有关键数据(如主要终点、次要终点、SAE等),将采用“双人独立录入”模式。即由两名经过培训的研究人员分别独立录入同一份数据,系统自动比对结果,任何不一致之处将生成“数据质疑”,反馈给研究者核对原始病历后确认修正。b.自动范围与逻辑检查:如10.1所述,系统在录入时即进行实时检查。c.人工数据审核:数据管理员将定期(如每周)从系统后台生成数据质疑报告,针对缺失数据、异常值、逻辑错误等,通过系统内部消息功能向中心研究者发出质询。研究者需在收到质询后72小时内核查原始医疗记录并在线回复或修正。d.源数据核查:研究监查员将定期根据预设的风险评估计划,将eCRF中的数据与患者的原始医疗记录(源数据)进行比对,以验证数据的一致性。 (3)数据保密与储存:a.保密性:研究网站将采用HTTPS加密协议进行数据传输。存储敏感信息的数据库将进行加密处理。访问权限严格按角色分配。b.数据储存:所有电子数据将储存在符合中国网络安全与个人信息保护法规的安全服务器上。研究结束后,数据库将被最终锁定。锁定后的分析数据库及所有源文件将按规定保存至研究结束后至少15年。c.归档:研究结束后,系统操作日志、权限管理记录、数据库变更记录等所有相关电子文档将一并归档,确保整个数据生命周期的可追溯性。

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

Electronic data management in this study will follow the ALCOA principles (attributable, legible, contemaneous, original, accurate, complete, consistent, enduring, and available) and implement the following procedures to ensure data quality, confidentiality, and security:(1) Data entry coding: a. Access control: Researchers will be provided with dedicated accounts and passwords. The system will record all user operation logs to ensure the “attributable” of data operations b. Data coding: All subjects will be identified with unique study numbers, and personal sensitive information such as patient names, ID numbers will not be directly recorded in the eCRF Categorical variables will be coded using preset codes during entry to ensure data standardization.(2) Data quality control measures: a. Double entry and verification: For key data (e.g., primary endpoints, secondary endpoints, SAEs, etc.), “double independent entry” mode will be applied. That is, the data will be independently entered by two trained researchers, and the system will automatically compare the results. Any discrepancies will generate “data queries,” which will be fed back to the investigator verify the original medical records and then confirm and modify. b. Automatic range and logic checks: As described in 10.1, the system will perform real-time checks entry. c. Manual data auditing: The data manager will regularly (e.g., weekly) generate data query reports from the system backend, addressing missing data, abnormal, logic errors, etc., and send them to the central investigator through the internal message function of the system. The investigator is required to verify the original medical records and reply or online within 72 hours after receiving the query. d. Source data verification: The study monitor will regularly compare the data in the eCRF with the patients’ original medical (source data) according to the preset risk assessment plan to verify data consistency.(3) Data confidentiality and storage: a. Confidentiality: The study website will HTTPS encryption protocol for data transmission. Databases storing sensitive information will be encrypted. Access rights will be strictly role-assigned. b. Data storage: All electronic data be stored in secure servers that comply with Chinese laws and regulations on network security and personal information protection. After the completion of the study, the database will be finally locked. The locked database and all source files will be kept for at least 15 years after the end of the study according to regulations. c. Archiving: After the completion of the study all relevant electronic documents such as system operation logs, access management records, database change records, etc., will be archived together to ensure traceability throughout the entire data lifecycle
