Comparative Study
Comparison of symptomatic cerebral spinal fluid leak between patients undergoing minimally invasive versus open lumbar foraminotomy, discectomy, or laminectomy.
Minimally invasive spine surgery (MISS) techniques have similar long-term outcomes compared to open surgery for patients undergoing 1- or 2-level discectomy, foraminotomy, or laminectomy. However, the rate of cerebrospinal fluid (CSF) leaks with both techniques has not been well established in the literature. This study sought to compare the rate and clinical impact of CSF leak in open lumbar foraminotomy, discectomy, or laminectomy with comparable MISS approaches. ⋯ In this study, there was a statistically significant decreased rate of CSF leak between an MISS approach and an open surgical approach. Furthermore, CSF leaks in open surgery have a higher probability of requiring lumbar drainage or reoperation to repair the durotomy.
