[Foreign body perforation of the thoracic esophagus]

Esophageal perforation due to foreign body (FB) ingestion is an unusual occurrence. This study aims to define diagnostic difficulties of esophageal perforation by FB.

A chart review of patients on our service with FB esophageal perforation was carried out. Diagnosis of perforation was made by CT scan and/or esophagoscopy. Surgery was indicated when a FB could not be removed endoscopically or on a case-by-case basis according to clinical/laboratory, radiologic, and/or endoscopic findings.

Seven patients (age range: 27 to 80 years) were admitted for esophageal FB perforation. All patients presented with dysphagia. Two patients presented with signs of sepsis more than 24 hours after FB ingestion. Perforation was diagnosed at initial evaluation in five cases (three by endoscopy, two by CT) and after FB extraction in two cases. Six patients underwent surgery (suture repair: n=4; esophageal exclusion: n=1; mediastinal drainage: n=1). Five surgeries were performed at the initial diagnosis and one after failure of medical management. Mortality was zero; one patient developed esophageal fistula.

Diagnosis of FB esophageal perforation is difficult and is delayed in up to a quarter of patients. The perforation can be due to the FB itself or may be incurred during endoscopic extraction. Both CT and endoscopy are necessary for diagnosis and treatment. Most patients require surgical intervention.
