Comparative Study Between Unilateral Biportal Endoscopy Technique and Percutaneous Endoscopic Transforaminal Discectomy for the Treatment of Lumbar Spinal Canal Stenosis
OBJECTIVE Both unilateral biportal endoscopy technique(UBE) and percutaneous endoscopic transforaminal discectomy(PETD) are minimally invasive and effective surgical procedures for lumbar spinal stenosis.The object of this retrospective study was to compare the clinical and radiological outcomes between UBE and PETD.
METHODS In the period from July 2020 to December 2020, using UBE or PETD to treat lumbar canal stenosis.Patients were classified into two groups based on the surgery they had undergone. Preoperative and postoperative MR image was used to evaluate the removal rate of lumbar disc herniated material by two surgical methods. The two surgical methods are also compared and evaluated in terms of operation time, incision size, hospitalization time, etc.
It was performed as a retrospective analysis of prospectively collected data on patients received spinal endoscopic decompression between July 2020 to December 2020 was conducted. All patients underwent lumbar MRI examination with the result of L5-S1 disc herniation，accompanied by claudication or lower extremity radiation pain and other nerve compression symptoms. The symptoms have not improved with conservative treatments including physical therapy, medication, and epidural injection procedures for a minimum of 12 weeks. Patients who hadprevious spine surgery, infection, trauma, tumors or spondylolisthesis were excluded. The surgery was performed by the same experienced spinal surgeon and the surgical patient were closely followed for 3 months after surgery.
The investigators performed two kinds of endoscopic lumbar discectomy：unilateral biportal endoscopy technique(UBE) and percutaneous endoscopic transforaminal discectomy(PETD).
