研究目的:

本研究旨在阐明老年结直肠癌患者术后延迟性肠麻痹(PPOI)的关键影响因素,并构建个体化预测模型,为优化围手术期管理提供循证依据,最终降低老年患者术后并发症风险。  

Objectives of Study:

This study aims to elucidate the key factors influencing postoperative prolonged ileus (PPOI) in elderly patients with colorectal cancer and to develop an individualized predictive model, thereby providing evidence-based support for optimizing perioperative management and ultimately reducing the risk of postoperative complications in elderly patients.

De-identified data will be shared upon request after the paper is published. Raw data will not be made publicly available. Please contact the principal investigator via email at [yuliang0206099@163.com], submit a research proposal, and sign a data use agreement.

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:

通过医院电子病历系统连续筛选出2026年03月31日及以前年龄≥60岁结直肠癌根治术患者,通过回顾性研究,收集患者人口学资料、术前疾病特点、手术相关、麻醉相关等基线临床特点资料,由研究者及时填写至数据收集表,以保证内容准确,总结及时。数据收集表一般不应涂改,如果确有错误需要修改,应当在修改处签名签日期。资料的保存:研究者应当使资料保存完整。按照我国GCP原则,资料保存应在研究结束后10年。

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

Consecutive screening was conducted via the hospital’s electronic medical record system to identify patients aged ≥60 years who underwent curative resection for colorectal cancer on or before March 31, 2026. Through a retrospective study, baseline clinical data—including demographic information, preoperative disease characteristics, surgical details, and anesthesia-related information—were collected. Investigators promptly entered these data into the case report form (CRF) to ensure accuracy and timeliness of summarization. The CRF should generally not be altered; however, if corrections are necessary, the investigator must sign and date the modification. Data storage: Investigators must ensure complete retention of all study documentation. Per China’s Good Clinical Practice (GCP) guidelines, such documentation must be retained for 10 years following study completion.
