Comparision of Endoscopic Discectomy and Microdiscectomy for the Treatment of Lumbar Spinal Stenosis

Plain-language summary

The purpose of this study is to conduct a multicenter comparison of the clinical efficacy of Endo-Surgi Plus endoscopic technique, UBE endoscopic technique, and microdiscectomy technique in the treatment of lumbar spinal stenosis, and to compare the differences in the incidence of complications, surgical trauma, and other aspects among the three surgical techniques for the treatment of lumbar spinal stenosis. Each group of patients received either Endo-Surgi Plus endoscopy, UBE, or microdiscectomy decompression through the Quadrant channel. All patients were routinely administered low-dose hormones, dehydrating agents, and neurotrophic drugs postoperatively. Patients were required to strictly avoid strenuous activities and heavy lifting in the lumbar region for three months after surgery. Upon discharge, patients were provided with the same lumbar and back muscle rehabilitation exercises and other postoperative recovery-related discharge education. Each group of patients was followed up for at least one year, with follow-up including outpatient visits, physical examinations, questionnaire scoring, and necessary auxiliary examinations. Both two endoscopic surgeries, as surgical techniques that have been used in clinical practice for many years, have their efficacy confirmed by various studies. The investigator proposes that these two techniques may have similar clinical efficacy to microdiscectomy, while also offering the advantage of being less invasive. The aim of this study is to validate these assumptions. At the same time, there may be some differences between the two endoscopic surgeries that require further verification.
