Improved repair of cervical esophageal fistula complicating anterior spinal fusion: free omental flap compared with pectoralis major flap. Report of four cases.

Esophageal injury is a serious complication of anterior cervical fusion. A team approach to the management of these cases is described. The authors performed spinal assessment, control of the fistula, and interposition of a vascularized flap between the spine and the esophagus. They compared the overall efficacy of the pectoralis major flap (pedicled; two cases) and omental flap (free; two cases).
