A case of dysfunctioning of the oesophageal opening is reported. The patient, aged 71 years, had had difficulty in swallowing for a long time, complicated by the recent onset of obvious dysphagia. Radiological examination of the oesophagus revealed the presence of a permanent notch in the posterior wall in the crico-pharyngeal region. The endoscope could not pass through the oesophageal opening but radiocinematography did not reveal any obvious organic lesion. The dysphagia and crico-pharyngeal notch disappeared after myotomy. This case is one the rare examples of pharyngo-oesophageal incoordination wrongly called crico-pharyngeal achalasia, as there does not appear to be any disorder of relaxation of the upper oesophageal sphincter, and this was demonstrated by the postoperative manometric study carried out in our patient.
本文报告一例食管开口功能障碍病例。患者71岁，长期吞咽困难，近期出现明显吞咽困难。食管放射学检查显示环状咽肌区域后壁有一永久性切迹。内镜无法通过食管开口，但放射电影造影未发现明显器质性病变。肌切开术后吞咽困难和环状咽肌切迹消失。该病例是咽食管不协调（误称为环状咽肌失弛缓症）的罕见例子，因为食管上括约肌似乎没有任何松弛障碍，这在我们的患者术后测压研究中得到了证实。
