Rare complication of the cervical spine trauma--traumatic esophageal fistula: case report and review of the literature.

BACKGROUND AND STUDY AIMS: Esophageal fistula due to cervical spine trauma is a rare, potentially fatal complication, which changes significantly the treatment and the prognosis of the trauma patient. There is scarce data regarding this associated pathology of cervical trauma and it consists only of isolated cases, most of them being reported as a complication of the surgical treatment. We present the case of a female patient who suffered a fall from a wagon and who was diagnosed at presentation with cervical fracture and esophageal fistula. Patient: A 65 years old female who suffered a fall from a train wagon presented for intense neck pain and bilateral brachial paresis. The MRI exam showed a C6-C7 fracture with bilateral facet dislocation in the context of a degenerative, spondylotic cervical spine. It also showed an anterior fragment from the C7 body, in contact with esophageal adventitia. The patient underwent surgery.

RESULTS: A C6 corpectomy was performed, with arthrodesis with bone graft and cervical plate fixation. 24 hours after the procedure, the clinical signs of an esophageal fistula appeared and a CT-scan revealed the typical aspects of that complication. The patient underwent a second surgery in collaboration with the general surgeon with a good outcome and complete neurological recovery.

CONCLUSION: In the case of cervical spine trauma the imaging exploration has to look for potential signs of lesions to the neighboring vital structures. Although a rare complication of cervical trauma, esophageal fistula represents a formidable complication and requires immediate surgical sanction, the only factor decisive for a good prognosis.
