FOREIGN-BODY PERFORATION OF THE NORMAL ESOPHAGUS

Over an 11-year period, 12 patients with foreign body perforation of a previously normal oesophagus were treated in our institution. The foreign bodies were most commonly bones (10 cases), 5 of which were chicken bones; other species were pigeon, rabbit, veal, pork and fish (one each); 2 perforations were due to swallowed dentures. The mean age was 60 years (range 42-73) and 6 patients were female. A degree of psychosocial dysfunction was present in 3 patients. Seven patients presented late (> 48 h after ingestion). The commonest presenting symptoms were fever and pain (8 patients). Other symptoms included dysphagia (7), respiratory distress (3), and late cervical abscess formation (3). The diagnosis was established by contrast oesophagography or rigid oesphagoscopy. A third of the perforations were cervical, the remainder intrathoracic. All patients were treated by surgical drainage with or without primary closure of the perforation. There were no operative deaths. Five patients developed postoperative oesophageal teaks which required reoperation in 1 patient. All patients were well and swallowing normally on discharge from hospital. Follow-up endoscopy or oesophagography was carried out in all patients and confirmed the absence of oesophageal disorders. Foreign body perforation of the oesophagus is a rare but important subentity of oesophageal perforation which responds well to surgical treatment.
