AbstractMinimally invasive modalities have demonstrated efficacy in the treatment of neurogenic claudication. Direct comparisons, however, between complication rates of these newer techniques with open surgical techniques for lumbar decompression are lacking. This single-institution study examined neurogenic claudicants between August 2007 and June 2009. A total of 26 patients received open surgical decompression, and 23 patients microendoscopic decompression. Baseline demographic characteristics, peri-operative morbidity and mortality, length of hospital stay, and final disposition following hospitalization were recorded. Morbidity was divided into major and minor categories as defined by degree of requisite intervention and adverse impact on hospital stay. Average age, number of surgical levels, and pre-operative American Society of Anesthesiologists Physical Status Index scores were similar in each group (p>0.05). While minimally invasive surgery may be associated with slightly longer operative times, there is decreased blood loss, shorter hospital stays, and likely decreased requirements for ancillary support services upon discharge.Copyright © 2011 Elsevier Ltd.
