Extremely Rare Complications in Uniportal Spinal Endoscopy: A Systematic Review with Unique Case Analyses.

Abstract

Background: Endoscopic spine surgery represents a significant advancement in the minimally invasive treatment of spinal disorders, promising reduced surgical invasiveness while aiming to maintain or improve clinical outcomes. This study undertakes a comprehensive review of the literature on endoscopic spine surgery, with a particular focus on cataloging and analyzing the range of complications, from common postoperative issues to more severe, casuistic outcomes like dural tears and nerve damage. Methods: Our methodology encompassed a detailed review of meta-analyses, prospective randomized trials, cohort studies, and case reports to capture a broad spectrum of complications associated with endoscopic spine techniques. The emphasis was on identifying both the frequency and severity of these complications to understand better the procedural risks. Results: The findings suggest that endoscopic spine surgery generally exhibits a lower complication rate compared to traditional surgical approaches. Nonetheless, the identification of specific, rare complications peculiar to endoscopic methods underscores the critical need for surgeons' advanced skills, continuous learning, and awareness of potential risks. Conclusions: Recognizing and preparing for the potential complications associated with the rapid adoption of endoscopic techniques is paramount to ensuring patient safety and improving surgical outcomes in minimally invasive spine surgery.
