RESUMEN
Achalasia can be provoked by organic causes, and it is called secondary achalasia. Sometimes it is very difficult to distingush secondary achalasia from primary achalasia. We report a case of secondary achalasia due to recurrence of stomach cancer. A 45-year-old man came to our hospital due to three months history of dysphagia and regurgitation. Barium esophagogram showed concentric narrowing at the distal esophagus and dilatation of proximal esophagus. The esophagogastroduodenoscopy showed stenosis of gastroesophageal junction and the endoscope could not pass through it, but there was no evidence of malignancy. Esophageal manometry showed aperistalsis, compatible with achalasia. Abdominal CT showed soft tissue density near the gastroesophageal junction. However it was not possible to differentiate whether it was due to adhesion or malignancy. For correct diagnosis and treatment, explorolaparotomy was performed and it was diagnosed as secondary achalasia due to recurrence of stomach cancer.
