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. |

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. |
