1. 符合克罗恩病(CD)的诊断标准; 2. 内镜及影像学(如 CT/MR 小肠造影或经腹壁肠道超声)证实回盲瓣存在单一或主要狭窄病变,狭窄长度 <= 5 cm; 3. 狭窄以纤维性狭窄为主,无明显活动性穿通或脓肿形成征象; 4. 有慢性或间断性梗阻相关症状,如腹痛、腹胀、排气排便减少等; 5. 年龄 18~75 岁,性别不限; 6. 受试者一般状况可耐受内镜操作及镇静/麻醉; 7. 近 4 周内 CD 基础治疗方案(如 5-ASA、免疫制剂、生物制剂等)相对稳定,无剂量大幅调整; 8. 受试者自愿参加本研究,充分理解研究目的、方法和可能风险,签署书面知情同意书。 |
||||||||||||||||||||||
|
Inclusion criteria |
1. Meets the diagnostic criteria for Crohn’s disease (CD); 2. Endoscopy and imaging studies (such as CT/MR enterography or transabdominal intestinal ultrasound) confirm a single or predominant stricture at the ileocecal valve, with a stricture length <= 5 cm; 3. The stricture is predominantly fibrotic, with no evidence of active penetrating disease or abscess formation; 4. Presence of chronic or intermittent symptoms related to obstruction, such as abdominal pain, bloating, and reduced passage of gas and stool; 5. Aged 18–75 years, regardless of gender; 6. The subject’s general condition is sufficient to tolerate endoscopic procedures and sedation/anesthesia; 7. The baseline treatment regimen for CD (e.g., 5-ASA, immunomodulators, biologics, etc.) has been relatively stable within the past 4 weeks, with no significant dose adjustments; 8. The subject voluntarily participates in this study, fully understands the study objectives, methods, and potential risks, and signs a written informed consent form. |
||||||||||||||||||||||
|
排除标准: |
1. 狭窄长度>5 cm或多发狭窄、明显成角,预判EBD风险高或无法完成者; 2. 影像或内镜提示深溃疡显著、活动性瘘道、邻近脓肿或急性完全梗阻; 3. 近期(3个月内)同部位接受过EBD/手术,影响评估者; 4. 凝血功能明显异常或抗凝/抗血小板治疗无法停用者; 5. 严重心肺肝肾功能不全、活动性感染或妊娠/哺乳期; 6. 研究者认为不适合入组的其他情况。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Stricture length > 5 cm, or multiple strictures/marked angulation, with anticipated high EBD risk or inability to complete the procedure; 2. Imaging or endoscopy suggests prominent deep ulcers, active fistula, adjacent abscess, or acute complete obstruction; 3. EBD or surgery at the same site within the past 3 months that would affect evaluation; 4. Significant coagulation abnormalities, or anticoagulant/antiplatelet therapy that cannot be discontinued; 5. Severe cardiopulmonary/hepatic/renal insufficiency, active infection, or pregnancy/lactation; 6. Other conditions deemed unsuitable by the investigator. |

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: |
采用统一CRF/Excel数据库双人核对录入。关键变量(球囊规格、最大扩张直径、PRP制备参数、IUS测量值)实行二级核查。IUS尽量由固定超声医师按统一报告规范执行,测量取三次平均。IUS原始图像/视频及关键内镜图像以受试者编号匿名化保存,建立“图像—数据”对应索引;建议对至少10%的IUS测量值进行第二观察者复核并记录一致性(探索性)。研究中仅收集与本研究相关信息,采用受试者编号进行去标识化管理;资料保存期限按医院及适用法规要求执行 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
A unified CRF/Excel database is used for double-person verification and entry. Key variables (balloon specifications, maximum expansion diameter, PRP preparation parameters, and IUS measurement values) are subject to secondary verification. IUS should be carried out by a fixed ultrasound physician as much as possible in accordance with a unified reporting standard, and the average of three measurements should be taken. The original IUS images/videos and key endoscopic images were anonymized and saved with subject numbers, and a "image-data" corresponding index was established. It is recommended to conduct a second observer review of at least 10% of the IUS measurements and record the consistency (exploratory). Only information related to this study was collected in the research, and the subject numbers were used for de-identification management. The retention period of the data shall be implemented in accordance with the requirements of the hospital and applicable regulations |
