ABSTRACT

Introduction and objective: Endoscopic decompression has emerged as an effective and minimally invasive therapeutic alternative for the management of adjacent-level stenosis in patients previously undergoing lumbar fusion. This condition, known as Adjacent Segment Disease (ASD), often manifests years after the surgical procedure, with clinical symptoms such as sciatica, neurogenic claudication, and progressive functional impairment. This study presents a series of clinical cases investigating the results of the endoscopic approach in patients diagnosed with foraminal and central stenosis at a single level adjacent to fusion. Methods: The fully endoscopic technique used allows direct access to the stenosed area with minimal aggression to surrounding tissues, promoting effective neural decompression, reduced perioperative morbidity, and accelerated recovery. Results and conclusion: Preliminary results suggest that endoscopic decompression may represent a viable and advantageous strategy compared to conventional approaches, especially in patients at high surgical risk or seeking less invasive options.
