Spinal epidural abscess successfully treated with biportal endoscopic spinal surgery

Surgical decompression and antibiotic therapy are the treatments of choice for patients with spinal epidural abscess (SEA). Surgical treatment included decompression, evacuation of abscess, and debridement. Recently, minimal invasive surgery has been introduced more widely, and biportal endoscopic spinal surgery have shown satisfactory clinical outcomes compared with traditional open surgery. The purpose of this study was to evaluate the efficacy of biportal endoscopic spinal surgery for the treatment of SEA.From January 2016 to June 2017, 13 patients who underwent biportal endoscopic spinal surgery under the diagnosis of SEA were retrospectively enrolled in this study. The surgical indications of the enrolled patients included SEA with or without early stage spondylodiscitis who had neurological symptoms. Periopertaive data and clinical outcomes were assessed by regular serologic testing, imaging studies, physical examination, visual analog scale, Oswestry Disability Index and modified Macnab criteria.Offending pathogens were identified in seven (54%) of 13 biopsy specimens. Appropriate intravenous antibiotics for the identified pathogens isolated from infected tissue biopsy cultures were administrated to patients for at least 30 days. All patients reported satisfactory relief of pain and neurological symptoms after surgery. No surgery-related complications and recurrences were found after 2 years follow up.Biportal endoscopic spinal surgery may be an effective alternative to traditional open surgical decompression for the treatment of SEA.
