Abstract
A 58 year-old male made a deglutition of 4 hooked artificial teeth made of synthetic resin along with mochi (rice cake). The trial to take it out under esophagoscope from the thoracic esophagus was not successful. And it made an abscess in surrounding region, causing severe symptoms. Therefore, esophageal incision was performed and the foreign body was removed. It is conceivable, in the dangerous case which might cause severe complication by the violent removal of foreign body under autoscope, it is better to perform the esophageal incision especially when the body lies in the cervic region of the esophagus.
