Surgical treatment of aortoesophageal fistula induced by a foreign body in the esophagus: 40 years of experience at a single hospital.

BACKGROUND

Aortoesophageal fistula (AEF) is a rare but usually fatal complication of a foreign body in the esophagus. Little effective therapy exists to cure an AEF induced by esophageal foreign body. This report describes the authors' 40 years of experience treating patients with AEF caused by a foreign body and compares different treatments of patients and their clinical outcomes.

METHODS

The treatments of five patients with AEF caused by esophageal foreign body impaction were recorded at Wuhan General Hospital of Guangzhou Command from 1970 to 2011. One of these five patients was managed with nonsurgical measures, whereas three were treated by surgery with cardiopulmonary bypass, and one was treated by surgery with endovascular stent-graft repair.

RESULTS

All five AEF cases were confirmed by computed tomography, esophagogastroscopy, surgical findings, or two or both. The nonsurgically treated patient died of fatal hemorrhage. Another patient died during the postoperative period because of ventricular fibrillation (he had a history of coronary heart disease before the operation), and still another patient died of fatal hemorrhage during the surgery. The remaining two patients were completely cured by surgery: the one via traditional open thoracotomy with cardiopulmonary bypass and the other by surgery with endovascular stent-graft repair.

CONCLUSIONS

The authors' experience indicates that early diagnosis and an aggressive surgical treatment without delay is the only form of effective therapy for AEF. Endovascular stent-graft repair may be a safe and feasible method for treating patients with AEF that has potential as an improved treatment option for AEF.
