Abstract
OBJECTIVE: Aortoesophageal fistula (AEF) is a life-threatening complication of foreign body ingestion. The primary objective of this study was to describe a new management protocol for infected AEFs, which combines endovascular stent grafting and mediastinal drainage using video-assisted thoracoscopic surgery (VATS). METHODS: The authors analyzed the clinical data of 22 patients with ingested foreign bodies retrospectively, developed a classification system based on multidetector computed tomography (MDCT) findings for esophageal injuries induced by foreign body ingestion, and used this system and the clinical presentation to guide treatment. RESULTS: Depending on the MDCT findings, the esophageal injuries were divided into four grades: Grade I, non-penetrating injury (six patients); Grade II, penetrating injury with minimal infection (five patients); Grade III, potential AEF (five patients); and Grade IV, definite AEF (six patients). When a foreign body was visible on MDCT, a distance of ≤ 2 mm between the foreign body and aortic wall indicated potential or definite AEF. When no foreign body was visible, a typical clinical presentation, especially sentinel hemorrhage, and MDCT findings were used to establish the diagnosis. Only three Grade IV patients who underwent open surgery died of severe hemorrhage within 24 h postoperatively. The others patients had a good outcome with different treatment. CONCLUSIONS: The authors' experience indicates that MDCT was useful to classify esophageal injuries caused by foreign body ingestion which predicted the risk of AEF; endovascular stent grafting and VATS-guided mediastinal drainage would be a safe and minimally invasive method for treating patients with AEF and has the potential for improved treatment options for AEFs.
