  • Abstract
  • Look Inside

 There are few clinicians who think of achalasia and know endoscopic diagnostic criteria of achalasia when examining a patient with esophageal complaints. In this article, we mentioned the endoscopic diagnostic criteria of this disease published in 1984 and illustrated typical cases.

 The onset of the disease is usually seen in juvenile. The changes of the endoscopic findings and symptoms by the treatment are important. The relationship between the length of the disease and the carcinogenesis was discussed. The incidence of the malignant disease arising from achalasia was about 4.9%, although cancer arising from the Barrett's esophagus due to postoperative reflux esophagitis was common in the past, the mucosal squamous cell carcinoma has increased in number regardless of the operation. The endoscopic techniques how to detect these superficial lesions were mentioned.
