AB Background The aim of this study is to evaluate the safety and long-term clinical outcomes of transforaminal endoscopic foraminoplasty using local anesthesia and total intravenous analgesia (TIVA) in patients with single-level lumbar foraminal stenosis and unilateral leg pain.Methods Postoperative pain relief was self-evaluated by 46 consecutive patients using a visual analog scale (VAS) and Oswestry Disability Index (ODI). Patient scores were obtained before the procedure and at 6, 12, 24, and 60 months after surgery.Results Pain reduction of at least 50% in the VAS score and a decrease of at least 50% or more in ODI score was achieved in 37 of 46 patients throughout the follow-up period. Median VAS score decreased from 7.5 preoperatively to 2.5 postoperatively. Median ODI score decreased from 62% preoperatively to 15% postoperatively. All patients reached 24-month follow-up and 37 patients reached 60-month follow-up. There were no surgery-related complications.Conclusion Transforaminal endoscopic foraminoplasty performed under local anesthesia and TIVA produces sustained reduction in pain and improves functionality in patients with single-level lumbar foraminal stenosis without complications even in patients with comorbidities.Clinical Relevance Endoscopic foraminoplasty may be a useful adjunct to open micro decompressive surgery for patients with foraminal stenosis of the lumbar spineLevel of Evidence 4.
