Unusual foreign body in the upper cervical oesophagus: case report.

The vast majority of oesophageal foreign bodies pass through the gastrointestinal tract without causing complications: only in a few cases is endoscopic or surgical treatment required. A very unusual oesophageal foreign body is described herein, namely a clam shell, treated in a multidisciplinary setting and successfully removed using rigid endoscopy. The peculiarity of this case concerns the shape and location of the foreign body, the age of the patient and the absence of specific adult risk factors.
