诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

采用手术病理切片进行Masson三色染色,并根据组织学纤维化评分作为金标准,以准确评估肠道纤维化的存在及其严重程度。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Masson’s trichrome staining of surgical pathology specimens, combined with histological fibrosis scoring, will be used as the gold standard to accurately assess the presence and severity of intestinal fibrosis.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

采用基于磁共振肠道成像(Magnetic Resonance Enterography,MRE)的深度学习模型对肠道纤维化程度进行表征,综合分析多种MRE参数,包括磁化转移率(Magnetization Transfer Ratio,MTR)、表观扩散系数(Apparent Diffusion Coefficient,ADC)、增强增益百分比(Percentage of Enhancement Gain,%Gain)等。

Index test:

A deep learning model based on Magnetic Resonance Enterography (MRE) will be used to characterize the severity of intestinal fibrosis. The MRE parameters included in the analysis comprise Magnetization Transfer Ratio (MTR), Apparent Diffusion Coefficient (ADC), and Percentage of Enhancement Gain (%Gain), among others.

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

本研究的目标人群为经确诊患有肠道狭窄并接受手术治疗的克罗恩病患者,其组织病理学评估结果明确提示为纤维性狭窄。目标人群的招募工作将在五家炎症性肠病诊疗中心进行,其中两家诊疗中心的患者将被纳入模型训练组,其余三家诊疗中心的患者将纳入模型验证组。

例数:

Sample size:

234

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

The target population of this study consists of patients diagnosed with intestinal stenosis who have undergone surgical treatment for Crohn's disease, with histopathological evaluations clearly indicating fibrotic stenosis. Recruitment of the target population will be conducted across five inflammatory bowel disease treatment centers. Patients from two of these centers will be assigned to the model training group, while patients from the remaining three centers will be assigned to the model validation group.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

容易混淆的疾病人群为因肠道狭窄行手术治疗,术后病理提示克罗恩病相关炎症性狭窄,非克罗恩病相关性狭窄(如肠道肿瘤、肠结核、肠憩室、自身免疫相关疾病等)。

例数:

Sample size:

46

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

The easily confused disease population consists of patients who underwent surgical treatment for intestinal stenosis, with postoperative pathology indicating Crohn's disease-related inflammatory stenosis, rather than non-Crohn's disease-related stenosis (such as intestinal tumors, intestinal tuberculosis, intestinal diverticula, autoimmune-related diseases, etc.).

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:

录入汇总流程: 管理人员将实施权限规定,确保只有经过授权的人员才能查询或录入数据。符合入组条件的患者基础信息将由医院的住院病历系统录入至登记的腾讯表格中。科研助手负责补充填写腾讯表格中关于肠道手术标本的情况、数量及储存位置,并对所有收到的标本进行汇总。研究人员将负责对应患者的MRE影像数据汇总。未经管理人员同意,任何人不得擅自删除、更改、复制、打印或输出任何保密数据及相关资料。 核对制度: 在患者入组、信息收集和标本采集过程中,均由两名以上的科研助理或研究人员进行确认。在标本采集、标记和存储时,将再次核实相关信息。在分析阶段,研究人员还将对影像、患者信息和标本的准确性进行复核。数据采集及源数据的管理人员每三个月进行一次抽查,以核对患者是否符合入组条件,并确认标本信息的准确性。

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

Data Entry and Summary Process: Management will enforce access regulations to ensure only authorized personnel can enter or query data. Patient information meeting inclusion criteria will be entered into a Tencent form from the hospital's medical record system. Research assistants will supplement this form with details about intestinal surgical specimens, including condition, quantity, and storage, and summarize all specimens. Researchers will summarize the MRE imaging data for the relevant patients. No one may delete, alter, copy, print, or output confidential data without management's consent. Verification System: During patient enrollment, information collection, and specimen collection, two or more research assistants or researchers will confirm the process. Relevant information will be verified again during specimen collection, labeling, and storage. In the analysis phase, researchers will recheck the accuracy of imaging, patient information, and specimens. Management will conduct a random audit every three months to verify patient inclusion criteria and confirm specimen information accuracy.
