Abstract

Background: Percutaneous endoscopic decompression (PED) is considered a minimally invasive and safe procedure in lumbar degenerative disease. Few authors report the success of PED for thoracic spinal stenosis (TSS) with thoracic myelopathy. The objective of this study was to compare the outcome of PED versus posterior decompressive laminectomy (PDL) for TSS.

Methods: We retrospectively reviewed 30 consecutive patients who underwent surgery for single-level TSS from January 1, 2015 to May 1, 2019.These patients were divided into PED (n = 16) and PDL(n = 14) group. Preoperative demographic characteristics and perioperative outcomes were reviewed. Pre- and postoperative neurological status was evaluated using the modified Japanese Orthopaedic Association (mJOA) score and the recovery rate (RR).

Results: The patients' mean age was 57.3 years (27-76) in PED group and 58.8 years (34-77) in PDL group. No statistical difference was found between two groups with regards to neurological status at pre-operative and final follow-up. The RR in PED group achieved the same improvement as PDL group (87.5% vs 85.7%, P > 0.05), while the PED brought advantages in operative time(m) (86.4 vs 132.1, p < 0.05), blood loss (mL) (18.21 vs 228.57, p < 0.05),drainage volume(mL) (15.5 vs 601.4, p < 0.05), and hospital stay (d) (3.6 vs 5.6, p < 0.05).

Conclusions: Both PED and PDL showed favorable outcome in the treatment of TSS. Besides, PED had advantages in reducing traumatization. In terms of perioperative quality of life, PED could be an efficient supplement to traditional posterior decompressive laminectomy in patients with TSS.
