The upper esophageal sphincter (UES) has various important functions, such as protection of the airway from aspiration and conduct of bolus into esophagus, which are controlled by complex neuronal mechanisms. The functions will be affected when there is malfunction of the UES due to various etiologies. Here we present an 80-year-old male with non-progressive dysphagia and patulous UES incidentally found on esophagoduodenoscopy. There are no documented cases of idiopathic patulous UES in literature. Endoscopists must be aware of this rare condition while evaluating a patient presenting with oropharyngeal dysphagia.
上食管括约肌（UES）具有多种重要功能，如保护气道防止误吸以及将食团导入食管，这些功能由复杂的神经机制控制。当UES由于各种病因出现功能障碍时，这些功能将会受到影响。在此，我们报告一例80岁男性患者，在食管十二指肠镜检查时偶然发现患有非进行性吞咽困难和UES松弛。文献中尚无特发性UES松弛的记录病例。内镜医师在评估有口咽吞咽困难的患者时必须意识到这种罕见情况。
