The purpose of this study is to report on intra- and peri-operative complications associated with working channel endoscopic spine surgery.
This study is a retrospective chart review of a multi-institutional patient cohort operated on by surgeons within the Endoscopic Spine Study Group (ESSG) between May, 2010 and June, 2017.
Our study cohort consisted of a total of 553 consecutive cases with an average age of 57 years. The most common procedure was an endoscopic discectomy (n = 377, 68%) followed by foraminotomy (n = 156, 28.2%), laminectomy (n = 55, 9.9%), and medial facetectomy (n = 29, 5.2%). Overall, the rate of intra- and perioperative complications was 2.7%. There were 3 durotomies (0.54%), 2 epidural hematomas (0.36%), 2 patients developed a complex pain disorder (0.36%), 4 recurrent disc herniations within 3 months (1.1%), 4 systemic complications (1.1%) and no wound infections. No risk factors were identified with regards to age, gender, approach or number of segments.
Endoscopic spine surgery is associated with favorable rates of intra- and peri-operative complications compared to literature reports of comparable MIS and open surgeries. Our report proposes safe and effective strategies for management of these complications.
