研究目的: |
主要目的: 比较电针组与常规对照组在预防结直肠癌腹膜转移减瘤术后患者发生延迟性术后肠梗阻(PPOI)的效果差异。主要结局指标为术后首次排便时间(小时),该指标是评估胃肠功能早期恢复和PPOI风险的敏感指标。 次要目的: 评估电针介入的安全性; 比较两组PPOI发生率的差异; 探讨电针预防PPOI的可能作用机制。 |

|
Objectives of Study: |
Primary Objective: To compare the effect of electroacupuncture versus conventional control in preventing prolonged postoperative ileus (PPOI) in patients after cytoreductive surgery for colorectal cancer with peritoneal metastasis. The primary outcome is the time to first postoperative bowel movement (hours), which is a sensitive indicator for assessing early recovery of gastrointestinal function and PPOI risk. Secondary Objectives: To evaluate the safety of electroacupuncture intervention; To compare the incidence of PPOI between the two groups; To explore the possible mechanisms of electroacupuncture in preventing PPOI. |

药物成份或治疗方案详述: |
(一)电针组 在常规加速康复外科(ERAS)路径的基础上,加用电针治疗。 选穴:双侧足三里(ST36)、双侧上巨虚(ST37)、双侧三阴交(SP6) 针刺方法:采用一次性无菌针灸针(0.30 mm × 40 mm),与皮肤呈90°角快速进针,针刺深度为15-25 mm,以患者出现酸、麻、胀、痛感(得气)为度 电针参数:得气后连接电针治疗仪,采用疏密波(10 Hz / 50 Hz交替),电流强度为0.1-1 mA,以针柄产生肉眼可见的规律性颤动且患者无不适为准 治疗时长:每次治疗持续20分钟 治疗频次:术后第1天至第4天,每日1次 治疗地点:患者床旁进行,无需转运 (二)常规对照组 仅接受常规ERAS路径护理,不接收任何形式的针灸治疗。ERAS方案包括: 术后尽早拔除导尿管和鼻胃管 早期离床活动 嚼口香糖 早期营养支持 多模式镇痛(避免常规使用阿片类药物) 预防性使用抗生素 |

Description for medicine or protocol of treatment in detail: |
(A) Electroacupuncture Group On the basis of the standard Enhanced Recovery After Surgery (ERAS) protocol, electroacupuncture treatment is added. Acupoint selection: Bilateral ST36 (Zusanli), bilateral ST37 (Shangjuxu), bilateral SP6 (Sanyinjiao) Needling method: Disposable sterile acupuncture needles (0.30 mm × 40 mm) are inserted perpendicularly (90° angle) to the skin, with a depth of 15–25 mm. The sensation of soreness, numbness, distension, or pain (Deqi) is sought. Electroacupuncture parameters: After Deqi, the needles are connected to an electroacupuncture device. Dense-sparse wave (alternating 10 Hz / 50 Hz) is used, with a current intensity of 0.1–1 mA, adjusted to produce visible regular vibration of the needle handle without causing discomfort to the patient. Treatment duration: 20 minutes per session Treatment frequency: Once daily from postoperative day 1 to day 4 Treatment location: Bedside, without transferring the patient (B) Conventional Control Group Patients receive only the standard ERAS protocol without any form of acupuncture treatment. The ERAS protocol includes: Early removal of urinary catheters and nasogastric tubes Early ambulation Chewing gum Early nutritional support Multimodal analgesia (avoiding routine opioid use) Prophylactic antibiotics |

盲法: |
总体设计: 本研究为开放性(非盲)设计,但由于电针干预的特殊性,无法对患者和针灸操作者实施设盲。 设盲对象: 结局评估者:设盲。负责收集术后首次排便时间、排气时间等结局指标的研究人员不知晓患者的分组情况。 统计分析者:设盲。统计分析由独立的统计师在盲态下完成,分析完成后或出于安全考虑需要揭盲时方可接触分组信息。 患者:不设盲。由于电针治疗的明显体感,患者无法被设盲。 针灸操作者:不设盲。操作者需要根据分组实施电针治疗,无法设盲。 减少偏倚的措施: 主要结局指标(术后首次排便时间)采用客观记录(患者日记 + 医疗记录核对) 疼痛评分等主观指标采用标准化量表 结局评估由不知分组情况的研究助理完成 统计分析由独立统计师在盲态下进行 |

Blinding: |
Overall Design This study is an open-label (non-blinded) design. Due to the nature of electroacupuncture intervention, blinding of patients and acupuncturists is not feasible. Blinding of the following parties: Outcome assessors:Blinded. Research personnel responsible for collecting outcome measures such as time to first postoperative bowel movement and time to first flatus are unaware of the group assignment. Statisticians:Blinded. Statistical analyses are performed by an independent statistician under blinded conditions. Unblinding occurs only after the completion of analyses or for safety considerations. Patients:Not blinded. Due to the distinct somatosensory experience of electroacupuncture, patients cannot be blinded. Acupuncturists:Not blinded. The acupuncturists need to know the group assignment to perform electroacupuncture treatment. Measures to Reduce Bias: The primary outcome (time to first postoperative bowel movement) is objectively recorded (patient diary + medical record verification) Subjective outcomes (e.g., pain scores) are measured using standardized scales Outcome assessments are performed by research assistants unaware of group assignment Statistical analyses are conducted by an independent statistician under blinded conditions |

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: |
一、数据采集方法 采集工具:采用病例报告表(CRF)记录所有研究数据,包括患者基线资料、干预实施情况、结局指标等。 采集人员:由经过统一培训且不知晓分组情况的研究助理负责数据采集。 采集流程: 住院期间:每日由医护人员记录排气、排便时间、症状评分等指标 患者日记:由患者或陪护记录首次排气/排便时间、症状严重程度、药物使用情况 术后随访:术后30天通过门诊复查或标准化电话访谈收集再入院率和GIQLI评分 质量控制:结局指标测量时有两名工作人员在场(一名记录,一名指导),两名工作人员均不知晓分组情况。 二、数据管理方法 数据标识:所有受试者数据以研究编号数字标识,不使用姓名,以保护隐私。 数据记录:数据当场记录于CRF,同时签署工作人员姓名及日期。如需修改,需保留修改痕迹并署名及日期。 数据存储:CRF存放于有锁的档案柜中,仅供研究人员查阅,不向研究小组以外人员透露。 数据录入:采用双人独立录入、逻辑校验,确保数据准确性。 数据库锁定:数据完成清理与核查后锁定数据库,由盲态统计师进行分析。 三、随访管理 提高受试者依从性:研究开始前做好受试者教育,强调研究意义 保持联系:使用微信、电话等方式与受试者或陪护保持联系,提醒干预时间和内容 退出处理:对于退出或更改治疗方案的受试者,如能继续随访,则继续收集结局数据,纳入ITT分析 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
I. Data Collection Method Collection tool: A Case Report Form (CRF) is used to record all study data, including patient baseline information, intervention implementation, and outcome measures. Collection personnel: Data are collected by trained research assistants who are blinded to group assignment. Collection process: During hospitalization: Medical staff record daily time to flatus, time to bowel movement, symptom scores, etc. Patient diary: Patients or caregivers record the exact time of first flatus/bowel movement, symptom severity, and medication use Postoperative follow-up: At 30 days post-surgery, readmission rate and GIQLI score are collected via outpatient visit or standardized telephone interview Quality control: Two staff members are present during outcome measurement (one records, one instructs). Both are blinded to group assignment. II. Data Management Methods Data identification: All subject data are identified by study number only, not by name, to protect privacy. Data recording: Data are recorded immediately in the CRF, signed and dated by the staff member. Any modifications must retain the original entry with signature and date. Data storage: CRFs are stored in a locked filing cabinet accessible only to research personnel and not disclosed to individuals outside the research team. Data entry: Double independent entry and logical verification are performed to ensure data accuracy. Database lock: After data cleaning and verification, the database is locked and analyzed by a blinded statistician. III. Follow-up Management Improving adherence: Patient education is provided before the study to emphasize the importance of participation Maintaining contact: WeChat, telephone, or other means are used to maintain contact with patients or caregivers to remind intervention schedules and content Handling withdrawals: For patients who withdraw or change treatment plans, if follow-up is possible, outcome data will continue to be collected and included in the ITT analysis |
