研究目的:

开发一种可越过胆道狭窄、在狭窄近端开口并回撤取样的“伞状”反向活检钳;并在单中心前瞻性连续入组的 ERCP 研究中,与常规正向活检钳(及刷检)进行同台、随机顺序的配对比较,评估其技术可行性与安全性、标本质量/尺寸以及以最终诊断为参照的总体诊断准确性。  

Objectives of Study:

To develop an umbrella-like reverse biopsy forceps that can traverse a biliary stricture and obtain retrograde biopsy bites from the proximal side, and to evaluate its ex vivo mechanical performance and in vivo feasibility and safety, as well as specimen quality/size and overall diagnostic accuracy versus conventional forward biopsy forceps (and brush cytology) during ERCP in a prospective single-center consecutively enrolled study using the final diagnosis as the reference standard.

Pathological results

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):

本研究待评估的诊断措施为反向活检钳经ERCP取材:将器械沿导丝越过狭窄至近端,在狭窄近端开口并回撤取样(研究中同时进行了刷检与常规正向活检钳取材,用于配对比较)。

Index test:

The index diagnostic test was ERCP-guided sampling with the reverse biopsy forceps, advanced over a guidewire across the stricture to the proximal side, opened upstream, and then retracted to obtain tissue. Brush cytology and conventional forward forceps biopsy were also performed for paired comparison within the same session.

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)

单中心前瞻性连续入组的胆道狭窄患者:影像学(CT/MRI 等横断面影像)提示疑似恶性胆道狭窄;计划行 ERCP 且拟进行 ERCP 引导下取材(刷检 + 钳活检)。

例数:

Sample size:

16

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):

Consecutively enrolled patients with biliary strictures highly suspected of malignancy, who were scheduled for ERCP with planned ERCP-guided tissue acquisition (brush cytology plus forceps biopsies).

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):

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 CRF 收集并记录受试者基线信息、影像学提示与狭窄特征、ERCP 操作与取材过程(刷检及两种活检钳取样顺序与次数)、病理结果、随访结局及不良事件。研究数据由研究团队从 CRF 手工录入至受密码保护的本地电子表格进行管理,实行分级权限访问与定期备份;数据按伦理要求进行去标识化处理,原始纸质 CRF 与电子数据分别在受控环境中保存以便追溯。

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

Standardized CRFs were used to capture and document baseline characteristics, imaging/stricture features, ERCP procedures and sampling details (brushing and the order/number of bites for both forceps), pathology results, follow-up outcomes, and adverse events. Data from CRFs were manually entered into a password-protected local electronic spreadsheet, with role-based access and regular backups. Data were de-identified in accordance with ethics requirements, and both paper CRFs and electronic files were stored in controlled environments for auditability.
