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：

本研究为前瞻性观察性研究，根据术中直肠实际保留长度自然分组，按统一纳入排除标准纳入研究对象。分别于入院时、术中及术后各固定时间节点系统采集临床资料。统一设计标准化病例观察记录表，由经过统一培训的专职研究人员完成数据采集与信息录入，规避信息偏倚。采集内容包括：受试者一般基线资料（性别、年龄、身体质量指数、NRS 2002 评分、糖尿病及心脑血管疾病等合并症、ASA 分级）；围手术期指标（直肠保留长度、手术时间、术中出血量、术后首次排气时间、术后住院时间、术后并发症），于术前及术后 3、6、12 个月通过住院记录、电话 / 微信随访及门诊复查，统一评估 Wexner 便秘评分、GIQLI 胃肠生活质量评分、腹痛腹胀评分、Wexner 肛门失禁评分，并完善肛门直肠测压检测。所有观察指标均参照统一临床标准评定，评估时间点全程固定一致，保证两组数据采集流程同质化、标准化。

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

This was a prospective observational study in which patients were naturally allocated into groups according to the actual length of the retained rectal stump measured intraoperatively. All participants were enrolled based on predefined inclusion and exclusion criteria. Clinical data were systematically collected at admission, during surgery, and at predetermined postoperative follow-up time points.A standardized case report form (CRF) was developed for the study, and all data collection and entry were performed by dedicated research personnel who had received uniform training, thereby minimizing information bias. The collected data included baseline demographic and clinical characteristics, such as sex, age, body mass index (BMI), Nutritional Risk Screening 2002 (NRS-2002) score, comorbidities (including diabetes mellitus and cardiovascular or cerebrovascular diseases), and the American Society of Anesthesiologists (ASA) physical status classification.Perioperative variables included rectal stump length, operative time, intraoperative blood loss, time to first postoperative flatus, postoperative length of hospital stay, and postoperative complications.Follow-up assessments were conducted preoperatively and at 3, 6, and 12 months after surgery through hospitalization records, telephone or WeChat interviews, and outpatient clinic visits. The Wexner Constipation Score, Gastrointestinal Quality of Life Index (GIQLI) score, abdominal pain and bloating scores, and Wexner Incontinence Score were uniformly evaluated at each follow-up time point. In addition, anorectal manometry was performed to assess anorectal function.All outcome measures were assessed according to standardized clinical criteria. The timing and procedures of data collection and evaluation were kept consistent throughout the study to ensure homogeneity and standardization between the two groups.
