作者报告一例足月顺产婴儿,于生后数日即出现吞嚥困难,吃奶时发生憋气和发绀。反复发热。X线检查显示肺部有浸润。最初认为是吞嚥神经肌肉功能失常所致,但多次钡餐检查和X线电影透视(Cinefluovoscory)检查,环咽肌处始终显示环形狭窄。食管镜检查见到该处粘膜下有一横行梗阻。经扩张后症状消失。环咽肌失弛缓症的特点是:X线造影检查于吞嚥初期在环咽肌狭窄以上之咽部有扩张,当吞嚥继续进行,咽肌收缩良好,而环咽肌仍持续狭 The authors report a full-term term delivery of a baby, swallowing difficulties a few days after birth, and suffocation and cyanosis during feeding. Repeated fever. X-ray examination showed infiltration of the lungs. Initially considered to be caused by swallowing neuromuscular dysfunction, but many barium meal examination and X-ray examination (Cinefluovoscory), the ring pharyngeal muscle always shows ring stenosis. Esophageal examination to see where there is a sub-mucous membrane obstruction. After the expansion of symptoms disappeared. Cystic pharyngeal achalasia is characterized by: X-ray angiography in the early stages of pharyngeal pharyngeal stenosis pharyngeal pharyngeal dilatation, when swallowing continues, pharyngeal muscle contraction is good, while the cricopharyngeal muscle is still narrow
