Abstract
Esophageal fistulas may occur in an advanced stage or as a potentially life-threatening complication of treatment. They can be divided into esophageal-respiratory and esophageal-aorta fistulas. The diagnosis is confirmed with fluoroscopy using dilute barium oral contrast, followed by thin-section computed tomography, which defines the precise location and extent of the fistula. Flexible esophagoscopy and bronchoscopy are required for confirmation and anatomic assessment of the suspected fistula and provide additional information for treatment planning. Contamination is traditionally controlled by surgical exclusion, along with a jejunal feeding tube. Currently, fully covered self-expanding metal stents are the primary treatment option.
