Two cases of delayed esophageal perforation following a pneumatic dilatation for the treatment of achalasia are presented. Esophagrams obtained immediately after pneumatic dilatation failed to reveal a perforation. Increasing symptoms prompted repeat contrast studies, at which time an esophageal perforation was demonstrated. The occurrence of delayed esophageal perforation after pneumatic intrumentation is emphasized. An ischemic etiology for this delayed perforation is postulated.
本文报告两例因贲门失弛缓症行气囊扩张术后发生延迟性食管穿孔的病例。气囊扩张术后立即进行的食管造影未显示穿孔。症状加重促使再次进行造影检查，此时发现了食管穿孔。强调了气囊扩张术后延迟性食管穿孔的发生情况。推测这种延迟性穿孔的病因是缺血。
