ABSTRACT

Objective: This retrospective study describes the clinical and functional outcomes of 80 patients who underwent totally endoscopic inter-laminar surgery for lumbar disc herniation between May 2018 and May 2020 at a private healthcare facility. Methods: Medical records were analyzed to collect demographic data, pre- and postoperative pain levels using the Visual Analog Scale (VAS), functional disability according to the Oswestry Disability Index (ODI), and procedure-related complications. Results: Fifteen days after surgery, a significant improvement in pain and disability levels was observed (p < 0.001). Pain decreased significantly in the first 30 days, remaining stable between 60 and 90 days (p < 0.05) and 90 and 180 days (p = 0.82). Regarding functional disability, patients achieved almost complete improvement at 30 days, with no statistically significant variation at subsequent intervals of 60, 90, and 180 days (p = 0.4; p = 1; p = 1, respectively). Conclusion: Minimally invasive techniques, such as interlaminar endoscopic lumbar discectomy, have been consolidating as a trend in modern neurosurgical practice, as they allow for faster, more precise procedures with lower morbidity.
