Three Cases of the Secondary Achalasia induced by Malignant Tumor


Esophageal achalasia is characterized by failure of the lower esophageal sphincter to relax normally during swallowing and aperistaltic movement of the esophageal body. The characteristics of the secondary achalasia induced by malignancy are similar to tbose of the primary achalasia. So the failurc in recognizing the underlying tumor may delay the diagnosis and treatment of underlying tumor. We experienced three cases of the secondary achalasia induced by malignancy. Clinical features, findings of the esophagogram and esophageal manometry for them were consistent with those of the primary achalasia. We could differentiate the secondary achalasia from the primary achalasia using esophagogastroduodenoscopy and abdominal computed tomogram.
