This study was prompted by a clinical association noted between reflux oesophagitis and upper oesophageal disorders. Patients with reflux oesophagitis have been shown to have a significantly raised resting cricopharyngeal pressure. Patients with reflux oesophagitis (36%) complaining of dysphagia localized to the throat also had a high resting cricopharyngeal pressure. Successful repair of a hiatus hernia restored the cricopharyngeal pressure to within the normal range. Four of the five patients studied who had a pharyngeal pouch also had a raised cricopharyngeal pressure.
本研究是由反流性食管炎与食管上段疾病之间的临床关联引发的。已证实反流性食管炎患者的环咽肌静息压力显著升高。主诉咽喉部吞咽困难的反流性食管炎患者(36%)的环咽肌静息压力也较高。食管裂孔疝成功修复后,环咽肌压力恢复至正常范围。所研究的5例有咽袋的患者中有4例环咽肌压力也升高。
