Percutaneous Transforaminal Endoscopic Decompression With Removal Of The Posterosuperior Region Underneath The Slipping Vertebral Body For Lumbar Spinal Stenosis With Degenerative Lumbar Spondylolisthesis: A Retrospective Study London Spine Lumbar Stenosis

The article discusses the use of percutaneous transforaminal endoscopic decompression (PTED) combined with the removal of the posterosuperior region underneath the slipping vertebral body (PRSVB) for the treatment of lumbar spinal stenosis (LSS) with degenerative lumbar spondylolisthesis (DLS). A study involving 44 patients showed favorable clinical outcomes with improved visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores, and modified MacNab criteria ratings at 12 months postoperatively. The results suggest that increasing the removal of PRSVB during PTED may be beneficial in alleviating symptoms in patients with LSS and DLS, though further long-term studies are needed to confirm these findings

Abstract

Background: Percutaneous transforaminal endoscopic decompression (PTED) is an ideal minimally invasive decompression technique for the treatment of lumbar spinal stenosis (LSS) with degenerative lumbar spondylolisthesis (DLS). The posterosuperior region underneath the slipping vertebral body (PRSVB) formed by DLS is an important factor exacerbating LSS in patients. Therefore, the necessity of removing the PRSVB during ventral decompression remains to be discussed. This study aimed to describe the procedure of PTED combined with the removal of the PRSVB and to evaluate the clinical outcomes.

Methods: LSS with DLS was diagnosed in 44 consecutive patients at our institution from January 2019 to July 2021, and they underwent PTED combined with the removal of the PRSVB. All patients were followed up for at least 12 months. The clinical outcomes were evaluated using the visual analog scale (VAS), Oswestry Disability Index (ODI), and modified MacNab criteria.

Results: The mean age of the patients was 69.5 ± 7.1 years. The mean preoperative ODI score, VAS score of the low back, and VAS score of the leg were 68.3 ± 10.8, 5.8 ± 1.0, and 7.7 ± 1.1, respectively, which improved to 18.8 ± 5.0, 1.4 ± 0.8, and 1.6 ± 0.7, respectively, at 12 months postoperatively. The proportion of patients presenting “good” and “excellent” ratings according to the modified MacNab criteria was 93.2%. The percent slippage in spondylolisthesis preoperatively (16.0% ± 3.3%) and at the end of follow-up (15.8% ± 3.3%) did not differ significantly (p>0.05). One patient had a dural tear, and one patient had postoperative dysesthesia.

Conclusions: Increasing the removal of PRSVB during the PTED process may be a beneficial surgical procedure for alleviating clinical symptoms in patients with LSS and DLS. However, long-term follow-up is needed to study clinical effects.
