Unilateral or Bilateral Percutaneous Endoscopic Debridement and Lavage Treatment for Lumbar Spinal Tuberculosis

OBJECTIVE: To compare the clinical outcome between bilateral percutaneous endoscopic debridement and lavage (PEDL) and unilateral PEDL treatment for lumbar spine tuberculosis (LST). METHODS: A total of 40 patients with LST who underwent either bilateral PEDL (group A) or unilateral PEDL (group B) were reviewed. Perioperative parameters were assessed by operative time, intraoperative fluoroscopy times, and days of postoperative continuous irrigation and vacuum drainage. Clinical outcomes were evaluated in the Oswestry Disability Index (ODI), visual analog scale (VAS), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). All patients were followed-up for at least 18 months after treatment. - RESULTS: The average operative time and intraoperative fluoroscopy time were increased in group A compared with those in group B. There was no statistical significance between the 2 groups in postoperative continuous irrigation and vacuum drainage days. The ESR and CRP curves in the 2 groups showed a similar trend during 18-month follow-up. The VAS and ODI in the 2 groups significantly decreased 6 and 18 months postsurgery. There was no significant difference in the incidence of complication between the 2 groups. - CONCLUSIONS: Two procedures yielded comparable and satisfactory results. Unilateral PEDL showed shorter operative time and decreased intraoperative fluoroscopy times compared with bilateral PEDL. We suggest the use of unilateral PEDL rather than bilateral PEDL in the treatment of LST.
