The evolution of endoscopy has been tumultuous since its beginnings as a “blind” percutaneous procedure to access the disk until the present state, in which complex decompressions and even fusions can be accomplished through subcentimeter incisions. Engineering has played a crucial role in this evolution with advances in optics, illumination, and instrumentation that have allowed surgeons to work safely and efficiently in smaller and smaller corridors. Finally, the adaptation of enhanced recovery after surgery protocols have complemented the benefits offered by spinal endoscopy to help patients return to the quality of life they seek through surgical intervention. In this article, we explore foundational elements of spinal endoscopy and look ahead to the future of this maturing field.

This situation is no different for spinal endoscopy, which has been continuously developing for decades and has only recently gained significant traction in North America. Patient selection can be challenging for even expert endoscopic surgeons, given the limited abilities of current technology for patients with multilevel disease. Anatomic limitations, such as iliac crest location and small foraminal dimensions, can restrict application of the transforaminal approach, considered the “workhorse” of endoscopic techniques. A paucity of dedicated training opportunities has led many to become late adopters or preclude exposure entirely, limiting the next generation of surgeons and expansion of the field. Finally, economic constraints, including capital expenses and issues with insurance reimbursement, have generated difficulties to widespread acquisition. Nonetheless, the future is bright for spinal endoscopy, with potential solutions to these issues already generating progress. In the present report, we have summarized these challenges and discussed some of the current steps underway to help alleviate their impact.

Smaller outer-diameter working-channel endoscopes have permitted safe usage in the cervical spine for full endoscopic decompressions. Endoscopic fusions have now been widely reported, leveraging compatible instrumentation for disc preparation and expandable interbody grafts. This ultra–minimally invasive technique has also enabled the performance of fusion procedures in awake patients under monitored anesthesia care, affording speedier recovery and treatment options for those unable to undergo general anesthesia. Revision surgery after open or minimally invasive posterior discectomy or instrumentation can now be performed with endoscopic techniques, which often leverage the transforaminal approach to avoid scar tissue and adhesions. These procedures, among other endoscopic surgeries, are now being increasingly performed in ambulatory surgery centers, as safe outcomes, economic benefits to the healthcare system, and patients' desire to recover at home are becoming more apparent. Finally, the standardization of endoscopic terminology, which has long been a confounder to proper communication and education in this field, has recently been addressed by leading experts in a consensus document, which will serve as the foundation for future collaborative advancements.
