ABSTRACT
BACKGROUND: Spinal epidural abscess is a rare but serious infectious disease that can rapidly develop into a life-threatening condition. Therefore, the appropriate treatment is indispensable. Although conservative treatment is justifiable in certain cases, surgical treatment needs to be considered as an alternative early on because of complications such as (progressive) neurological deficits or sepsis. However, traditional surgical techniques usually include destructive approaches up to (multilevel) laminectomies. Such excessive approaches do have biomechanical effects potentially affecting the long-term outcomes. Therefore, minimally invasive approaches have been described as alternative strategies, including endoscopic approaches. OBSERVATIONS: The authors describe a surgical technique involving a combination of two minimally invasive approaches (endoscopic and microsurgical) to drain a multisegmental (thoracolumbar) abscess using the physical phenomenon of continuous pressure difference to minimize collateral tissue damage. LESSONS: The combination of minimally invasive approaches, including the endoscopic technique, may be an alternative in draining selected epidural abscesses while achieving a similar amount of abscess removal and causing less collateral approach damage in comparison with more traditional techniques.
