Surgical intervention is often required when conservative treatments fail, but the choice between different surgical techniques remains a topic of ongoing debate. The objective of this study was to provide a comprehensive comparison of the safety and efficacy of endoscopic unilateral laminectomy with bilateral decompression (Endo\u2010ULBD) and posterior lumbar interbody fusion (PLIF) in the treatment of multi\u2010segmental lumbar spinal stenosis (MS\u2010LSS). Furthermore, the text provides detailed technical information regarding the Endo\u2010ULBD procedure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This retrospective comparative study was conducted from October 2019 to October 2022 and involved 73 patients diagnosed with MS\u2010LSS. Of the total number of patients, 36 were treated with Endo\u2010ULBD and 37 with PLIF. The technical parameters of both procedures were recorded, including perioperative factors such as patient demographic characteristics (age, gender, BMI), disease duration, number of surgical segments involved, type of anesthesia, duration of surgery, estimated blood loss (EBL), postoperative length of stay, time to discharge, use of intraoperative fluoroscopy, and any intraoperative complications. Clinical outcomes were evaluated using the Visual Analog Scale (VAS), the Japanese Orthopedic Association (JOA) score, and the Oswestry Disability Index (ODI), which were assessed preoperatively and at follow\u2010up. Radiologic improvement was quantified by comparing the preoperative and postoperative dural sac areas. Statistical analyses were conducted using paired <jats:italic>t<\/jats:italic> tests with a significance threshold of <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In comparison to the PLIF group, the Endo\u2010ULBD group exhibited a markedly shorter operative time, diminished intraoperative bleeding, accelerated recovery of ambulation, and a shorter postoperative hospitalization period. Moreover, the Endo\u2010ULBD group demonstrated a diminished prevalence of postoperative complications. However, it required a significantly greater number of intraoperative x\u2010ray fluoroscopies than the PLIF group (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Postoperative VAS, ODI, and JOA scores demonstrated notable improvement in both groups, with a more pronounced trajectory observed in the Endo\u2010ULBD cohort during the early postoperative period. Both surgical approaches resulted in a notable enlargement of the dural sac area. Neither group experienced any fatalities, irreversible nerve damage, or paralysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Endo\u2010ULBD demonstrated superior early clinical outcomes compared to PLIF, including shorter operative time, reduced blood loss, faster recovery, and fewer complications. Both techniques provided similar improvements in dural sac decompression, but Endo\u2010ULBD may offer a more efficient and minimally invasive treatment option for patients with MS\u2010LSS. However, the high frequency of intraoperative fluoroscopy remains a limitation, highlighting the need for improved surgical techniques and positioning
