Full‐Endoscopic Transforaminal Debridement and Decompression for Brucellar Thoracic Spinal Epidural Abscess: A Minimally Invasive Alternative to Open Surgery

Abstract

ObjectiveThoracic spinal epidural abscess (SEA) is a rare but dangerous condition, and traditional surgical methods are accompanied by extensive trauma and approach‐related complications. Here we introduce the technique of full‐endoscopic transforaminal debridement and decompression and evaluate its feasibility for treating brucellar thoracic SEA.MethodsWe performed thoracic full‐endoscopic transforaminal decompression and debridement on two patients with neurological deficits caused by brucellar SEA, which is mainly composed of granulation tissue rather than pus. Postoperative MRI was conducted to confirm the presence of any residual abscess compressing the nerves. Frankel grading was employed to assess the recovery of neurological function, and complications were documented.ResultsThere were no occurrences of dural tear, postoperative hematoma, or pulmonary complications. Their neurological function had significantly improved after surgery, and postoperative MRI confirmed no residual abscess compressing the spinal cord. During the 2‐year follow‐up, one patient achieved complete recovery (from Frankel‐C to Frankel‐E), while another patient improved from Frankel‐A to Frankel‐D. Neither patient experienced infection recurrence, instability, nor kyphotic deformity.ConclusionWe described the novel application of transforaminal endoscopic surgery in brucellar thoracic granulomatous SEA and preliminarily indicated the feasibility of this technique as a minimally invasive alternative to open surgery.
