Abstract
Introduction Despite all of the technical refinements, surgical treatment of herniated discs still remains controversial. The objective of the current prospective randomized study was to compare the outcome of patients with persistent sciatica secondary to lumbar disc herniation treated with either open discectomy (OD) or microendoscopic discectomy (MED) technique. Patients and Methods We performed a prospective controlled randomized study of 40 patients with sciatica caused by lumbar disc herniations nonresponsive to conservative treatment who underwent OD or MED with a 24-month follow-up period. Pre- and postoperative neurological status, pain, and functional outcome were evaluated. Other studied variables were the duration of the procedure, blood loss, time of hospital stay, and time to return to work. Statistical analysis with a p value less than 0.005 was performed. Results The only statistically significant differences found were for size of the incision, length of hospital stay, and operative time. The former two were greater in the OD group ( p < 0.01 and p = 0.05, respectively), and the latter was greater in the MED group ( p < 0.01). Conclusion The few parameters that were found to be statistically significant between the groups did not affect the overall outcome. In the current series, the final clinical and neurological results were similarly satisfactory in both the OD and the MED groups.
