Summary
Objective To analyze associations between anxiety and postsurgical clinical outcomes in patients
who underwent minimally invasive lumbar decompression surgery in addition to comparing
symptoms of anxiety and depression before and after surgery.
Methods This prospective cohort study of patients who underwent minimally invasive lumbar
decompression surgery. Clinical outcomes were measured before and 6 months after surgery
using the Visual Analog Scale (VAS), Global Perceived Effect of Change (GPE), Hospital
Anxiety and Depression Scale (HADS), and Oswestry Disability Index (ODI). Based on
the presurgical anxiety score, patients were categorized into anxious and non-anxious
patients, and the outcomes were compared.
Results The patients of both groups obtained similar results concerning the clinical outcomes
evaluated. Preoperative HADS scores decreased significantly 6 months after surgery
in both anxiety (8.70 ± 3.48 vs. 5.75 ± 3.91) and depression (6.95 ± 3.54 vs. 5.50 ± 2.99).
The VAS scale for the back (-2.8 ± 3.64) and legs (-5.5 ± 3.5) showed a reduction
in pain.
Conclusion Minimally invasive lumbar decompression surgery promoted clinical and functional
improvement, not being affected by preoperative anxiety symptoms. Mental health indicators
showed a significant reduction in symptoms 6 months after surgery.
