Non-obstructive dysphagia (NOD) is defined as symptomatic dysphagia in patients with negative endoscopic and radiographic workup. The management of NOD remains controversial as there is a discrepancy between different guidelines and clinical practice. Despite the lack of high-quality studies, empiric dilation for NOD is a common clinical practice among endoscopists and the approach varies between different clinical centers. In this review, we summarize the published literature on empiric dilation for NOD and propose a management algorithm for offering empiric dilation to patients presenting with dysphagia.
非梗阻性吞咽困难（NOD）定义为内镜和影像学检查均为阴性的有症状吞咽困难患者。尽管缺乏高质量的研究，但经验性扩张术仍是内镜医师治疗 NOD 的常用临床方法，且不同临床中心的方法也存在差异。在本文中，我们总结了关于 NOD 经验性扩张的文献，并提出了一种用于为出现吞咽困难的患者提供经验性扩张的管理算法。
