Abstract
The patient was a 67-year-old man who suffered from dysphagia since 40 years ago and diagnosed as esophageal achalasia 20 years ago. He visited our hospital because of an abnormal findings on a routine medical check-up in which upper gastrointestinal radiography demonstrated a sigmoid-type achalasia with a maximum diameter of 44 mm. Upper gastrointestinal endoscopy revealed a IIc lesion at 30 cm from incisor which was not stained by iodine. Pathological diagnosis was well differentiated squamous carcinoma. Endoscopic ultrasonography showed a slight thickening of the second layer that indicated T1a-LPM. First, esophageal cancer was treated by endoscopic submucosal dissection. Pathologically, the tumor was T1a-LPM, and was a superficial carcinoma. Because of minimal risk of cancer recurrence, he then underwent laparoscopic Heller-Dor cardioplasty. We herein report such a patient, with a review of the relevant literature.
