Abstract
We experienced three cases of esophageal foreign bodies, removal of which had failed with flexible esophagoscope by well trained gastroenterologists in other hospitals because of large size and sharp shape. Finally we removed them with a rigid esophagoscope under general anesthesia.Based on our experiences, we discussed the limitation of flexible esophagoscopy for the removal of esophageal foreign bodies.In a case of a large or sharp foreign body which seems impossible to pass through the cricopharyngeal pinchcock with the flexible endoscope, it might be the indication of the removal with a rigid scope or with an external approach under general anesthesia.
