Abstract:

Aim of this study was to investigate the capabilities, advantages and limitations of bilateral decompression via unilateral approach in decompressive-stabilizing procedures in patients with degenerative lumbar spine disease, and to develop the technology and its technical performance. The controlled study included 372 patients (age range was 27-74 years). All of them were operated due to clinical manifestation of lumbar spinal stenosis. The main group consisted of 44 patients who underwent bilateral decompression via unilateral approach with stabilization of involved segments. The control group included 328 patients who were operated using standard bilateral technique with stabilization. A total of 52 segments were treated in the first group and 351 in the second one. In all patients with neurogenic intermittent claudication symptoms relieved after decompressive-stabilizing surgery. Analysis of duration of surgery (considering 1 segment) demonstrated that less invasive technique requires as much time as conventional. However mean intraoperative blood loss in the first group was twice as low as the second. Neither patient from the first group required hemotransfusion while in the second group in 57 (17.4%) cases hemotransfusion was performed due to blood loss. In the early postoperative period in both groups intensity of pain (according to VAS) gradually decreased. Mean hospital stay was 9.9±3.1 day in the main group and 14.7±4.7 days in the control group. Bilateral spinal canal decompression via unilateral approach decreases surgical trauma, blood loss, complication rate and hospital stay. Postoperative results are comparable with conventional technique.
