Transsacral colon fistula: late complication after resection, irradiation and free flap transfer of sacral chondrosarcoma

Abstract

Abstract Background Primary sacral tumors are rare and experience related to accompanying effects of these tumors is therefore limited to observations on a small number of patients. Case presentation In this case report we present a patient with a history of primary sacral chondrosarcoma, an infection of an implanted spinal stabilization device and discuss the challenges that resulted from a colonic fistula associated with large, life threatening abscesses as late complications of radiotherapy. Conclusion In patients with sacral tumors enterocutaneous fistulas after free musculotaneous free flaps transfer are rare and can occur in the setting of surgical damage followed by radiotherapy or advanced disease. They are associated with prolonged morbidity and high mortality. Identification of high-risk patients and management of fistulas at an early stage may delay the need for subsequent therapy and decrease morbidity.
