Inpatient Outcomes of Surgical Treatment for Spinal Tuberculosis: 10-Year Results from the US National Inpatient Sample

Özet

AIM: To evaluate the association between in-hospital outcomes of patients with spinal tuberculosis and different surgical approaches.MATERIAL and METHODS: This population-based, retrospective observational study analyzed data of hospitalized patientsundergoing surgical treatment for spinal tuberculosis in the United States who were identified in the US Nationwide InpatientSample (NIS) between 2005 and 2014. The study cohort was stratified by posterior-only, anterior-only, and combined surgicalapproaches. Logistic and linear regression analyses were performed to evaluate associations between surgical approaches andpatient outcomes.RESULTS: Significant differences were found in postoperative complications, number of instrumented levels, and comorbidityscores (all p ≤ 0.033) between patients who received different surgical approaches. A univariate analysis demonstrated the combinedapproach was associated with significantly increased odds of postoperative complications compared with the posterior-onlyapproach. This association remained significant when following multivariate analysis after adjustments. For patients who receivedsurgery at the lumbosacral level, the anterior-only approach and combined approach were both associated with significantlyincreased odds of postoperative complications compared with the posterior-only approach. Among patients who received surgery atthe lumbosacral level, multivariate analysis showed that anterior-only and combined approaches were associated with significantlylonger length of stay.CONCLUSION: Among patients with spinal tuberculosis who are undergoing surgical treatment, a posterior-only approach wasassociated with fewer complications and shorter length of stay compared with an anterior-only or combination approaches whenperformed at the lumbo-sacral spinal level.
