研究目的:

本项目拟采用前瞻性诊断验证研究设计,拟招募110例典型临床症状患者。以ROMs检查结果为参考标准,次日进行标准化GFU 检查,并通过严格的盲法评估收集数据。最终将系统计算GFU的诊断效能指标,确立评估胃轻瘫的最佳参数和阈值。旨在为临床提供一种安全、便捷、经济高效的胃轻瘫筛查手段。  

Objectives of Study:

This project proposes a prospective diagnostic validation study, enrolling 110 patients with typical clinical symptoms. Using ROMs examination results as the reference standard, participants will undergo standardized GFU examination on the following day, with data collected through rigorous blinded assessment. The diagnostic performance of GFU will be systematically evaluated, and the optimal parameters and thresholds for assessing gastroparesis will be established. This study aims to provide a safe, convenient, and cost-effective screening method for gastroparesis in clinical practice.
