Endoscopic discectomy procedures in patients with CLSS present more significant challenges in achieving sufficient decompression than those in patients with noncongenital spinal stenosis. To our knowledge, no studies disaggregate the outcomes of endoscopic discectomy between CLSS and non\u2010CLSS patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To compare the clinical outcomes of full endoscopic interlaminar discectomy (FEID) in patients diagnosed with congenital lumbar spinal canal stenosis (CLSS) against those with non\u2010congenital lumbar spinal canal stenosis (non\u2010CLSS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Between 2016 and 2020, patients who underwent full\u2010endoscopic discectomy at our institution were enrolled in this study. Inclusion criteria included individuals under 50\u2009years of age, presenting symptoms of lumbar disc herniation with a positive straight leg raise test, failed conservative treatment, and no prior lumbar spine surgeries. Outcomes measured included operative times, visual analog scale (VAS) scores, Oswestry Disability Index (ODI), and modified Macnab criteria at 1\u2009day, 2\u2009weeks, 6\u2009weeks, 3\u2009months, 6\u2009months, 1\u2009year, and 2\u2009years postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Fifty\u2010six patients participated in the study, with 22 in the CLSS group and 34 in the non\u2010CLSS group.
