Degenerative lumbosacral spinal stenosis is one of the leading causes of chronic pain and disability in elderly patients. Single-portal endoscopic interlaminar bilateral decompression is a promising minimally invasive method. However, prospective data are limited. Material and methods. A single-center prospective study included 50 patients with central single-level lumbosacral degenerative stenosis who underwent single-portal endoscopic interlaminar bilateral decompression through a unilateral approach. VAS, ODI, MacNab and GAS scores were assessed. We also analyzed surgery time and 6-month morbidity. Results. By the 6th month, VAS scores of low back and leg pain decreased by 5.6 and 6.7 points. ODI score decreased by 48.2 points (p&lt;0.001). Satisfactory outcomes according to MacNab scale comprised 80%, GAS \u22650 \u2013 82%. Dural damage and explorations were observed in 4% of cases, and there were no infectious complications. Mean surgery time decreased from 230 to 127 min along with accumulation of experience (p&lt;0.001). Conclusion. Single-portal endoscopic interlaminar bilateral decompression from a unilateral approach is an effective option for degenerative lumbosacral stenosis. Multiple-center studies with long-term follow-up are needed to evaluate long-term outcomes and compare this surgery with other minimally invasive techniques.<\/jats:p>","DOI":"10.17116\/neiro20269005116","type":"journal-article","created":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T05:26:47Z","timestamp":1792128407000},"page":"16","source":"Crossref","is-referenced-by-count":0,"title":["Single-portal endoscopic decompression for degenerative lumbosacral spinal stenosis: a prospective single-center study"],"prefix":"10.17116","volume":"90","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-6787-9136","authenticated-orcid":false,"given":"L.R.","family":"Gabrielyan","sequence":"first","affiliation":[{"name":"Burdenko Neurosurgical Center","place":["Moscow, Russia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9976-948X","authenticated-orcid":false,"given":"N.A.","family":"Konovalov","sequence":"additional","affiliation":[{"name":"Burdenko Neurosurgical Center","place":["Moscow, Russia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8637-9079","authenticated-orcid":false,"given":"R.A.","family":"Onoprienko","sequence":"additional","affiliation":[{"name":"Burdenko Neurosurgical Center","place":["Moscow, Russia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6184-7481","authenticated-orcid":false,"given":"E.S.","family":"Brinyuk","sequence":"additional","affiliation":[{"name":"Burdenko Neurosurgical Center","place":["Moscow, Russia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8813-2793","authenticated-orcid":false,"given":"S.V.","family":"Kaprovoy","sequence":"additional","affiliation":[{"name":"Burdenko Neurosurgical Center","place":["Moscow, Russia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8782-850X","authenticated-orcid":false,"given":"B.A.","family":"Zakirov","sequence":"additional","affiliation":[{"name":"Burdenko Neurosurgical Center","place":["Moscow, Russia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6743","reference":[{"key":"key-10.17116\/neiro20269005116-1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2022.5921"},{"key":"key-10.17116\/neiro20269005116-2","doi-asserted-by":"publisher","DOI":"10.17650\/1683-3295-2024-26-4-14-21"},{"key":"key-10.17116\/neiro20269005116-3","doi-asserted-by":"publisher","DOI":"10.17116\/neiro20218504187"},{"key":"key-10.17116\/neiro20269005116-4","doi-asserted-by":"publisher","DOI":"10.17650\/1683-3295-2020-22-1-93-102"},{"key":"key-10.17116\/neiro20269005116-5","unstructured":"Hamdan TA, Abdul Hassan AS.
