## 1 Introduction  
Spinal endoscopy, though introduced over two decades ago, has experienced rapid development in the last 10-15 years thanks to technological advancements [1]. Initially limited to the treatment of discopathies, its application now extends broadly within the realm of spinal degenerative diseases, including multi-level stenosis and spinal stabilization [2]. These advancements open new horizons, suggesting that the only limit to endoscopy's application might be our imagination. The method's utilization is also expanding into oncology [3] and spinal infections [4], where its minimally invasive approach and operation in a fluid environment--ensuring continuous irrigation of the surgical field--seem to be an ideal solution. Spinal endoscopy, a minimally invasive technique used for diagnosing and treating various spinal conditions, has gained traction in recent years due to its favorable risk-benefit profile. The primary benefits of spinal endoscopy include reduced post-operative pain, shorter recovery times, and lower rates of complications compared to traditional open surgery. Patients typically experience a quicker return to normal activities, enhancing overall quality of life. However, risks associated with spinal endoscopy may include bleeding, infection, nerve injury, and incomplete decompression, necessitating careful patient selection and meticulous procedural execution. The relatively low complication rates, combined with the effectiveness in managing conditions like herniated discs and spinal stenosis, make spinal endoscopy an attractive option. Overall, as techniques and technologies advance, spinal endoscopy continues to evolve, promoting safer and more effective management of spinal disorders. Spinal infections, while relatively rare, present significant public health concerns with varied epidemiological profiles. The estimated prevalence of spinal infections ranges from 0.2 to 2.0 cases per 100,000 individuals, with an incidence rate of approximately 2.5 to 18 cases per million annually [5]. The condition shows a male-to-female ratio of about 2:1, suggesting a higher susceptibility among males. The impact of spinal infections on activities of daily living (ADLs) can be profound, often leading to significant physical disability and impaired quality of life (QOL) [6]. Individuals may experience chronic pain, mobility issues, and psychological distress, ultimately reducing their ability to perform daily tasks. Furthermore, years lived with a disability (YLD) can be considerable, as many patients endure prolonged symptoms and complications, contributing to the global burden of disease (GBD) assessments that indicate substantial economic costs associated with healthcare utilization and loss of productivity. Other epidemiological data reveal an increasing incidence linked to risk factors such as diabetes, immunosuppression, and certain infectious conditions, underscoring the need for increased awareness and timely intervention. Spinal infections, with their unique challenges, represent a promising domain for the application of endoscopy [2,7]. The intricacies of managing primary spondyliscitis, alongside infections arising as post-operative complications, underscore the need for innovative treatment approaches. The aim of our article is to conduct a comprehensive literature review to assess whether endoscopy could herald a new standard in the treatment of these diverse spinal infections. This inquiry is enriched by the presentation of a series of our own cases, which illustrate the practical application of endoscopic techniques in both contexts. Our study endeavors not merely to map the current landscape of knowledge but also to illuminate the potential advantages and hurdles linked with the expanded use of endoscopy in the management of inflammatory spinal diseases. By doing so, we seek to underline endoscopy's versatility and efficacy, whether confronting primary infections of the spine or tackling the complex challenges presented by post-operative infections.
