Objective: Interlaminar endoscopic spine surgery has been introduced and utilized for lum bar lateral recess decompression. We modified this technique and utilized it for bilateral lat eral recess stenoses without significant central stenosis. Here we present the surgical details and clinical outcome of ligamentum flavum sparing unilateral laminotomy for bilateral re cess decompression (ULBRD). Methods: Prospectively collected registry for full-endoscopic surgeries was reviewed retro spectively. One hundred eighty-two consecutive cases from a single center between Sep tember 2015 and March 2021 were reviewed and 57 of them whom underwent ULBRD were enrolled for analysis. Basic patient demographic data, perioperative details, surgery related complications, and clinical outcome were reviewed. The detailed surgical technique is presented as well. Results: Among the 57 patients enrolled, 37 were males while the other 20 were females. The mean age was 58.53 ± 14.51 years, and a bimodal age distribution at the age of mid-fif ties and mid-sixties or older was noted. The later age-peak was related to coexistence of de generative scoliosis. The average operative time per lamina was 70.34 ± 20.51 minutes and mean length of stay was 0.56 ± 0.85 days. Four perioperative complications were reported (7.0%) and the overall reoperation rate at the index level within 1 year was 8.8%. The pre operative back/leg visual analogue scale scores and functional outcome scales including Eu roQol-5 dimension questionnaire, Oswestry Disability Index presented significant improve ment immediately after surgery and were maintained until final follow-up. Conclusion: ULBRD for bilateral lateral recess stenoses without significant central stenosis resulted in good clinical outcomes with acceptably low perioperative complications rates. Sufficient decompression was achieved with the central ligamentum flavum being preserved.
