Abstract
Objective: The aim of this work is to compare between results of microscopic decompression and standard laminectomy for treatment of lumbar canal stenosis. Methods: This is Prospective Randomized Controlled Study, where patients having lumbar canal stenosis were evaluated preoperatively both clinically and radiologically. Randomization was planned by performing microscopic surgery in odd numbers and open standard surgery in even numbers. Patients were evaluated and followed up for outcomes after 1 and 3 months.Results: We operated 36 patients in this study, 18 patients operated with microscopic decompression (group 1) and 18 patients operated with open standard laminectomy(group 2),the median age of presentation in this study was 57 years, there were 23 males and 13 females. Postoperative pain improvement was better in (group 1),hospital stay was less (group 1),blood loss was less in (group 1),bone loss was less in (group 1) and postoperative complications were less in (group 1).Conclusion: Microscopic decompression allows good surgical Visualization and less traumatic to the involved tissues.Interestingly, the results of this study indicated that microsurgery reduce hospitalization time, improves the overall surgery-related outcome. The main differences between the two procedures were length of the incision and blood loss. We found that microscopic decompression allows patients earlier return to work and/or normal life with less reliance on postoperative narcotic analgesic agents
