COMPARATIVE STUDY OF EFFICIENCY OF DESTANDAU ENDOSCOPIC DISCECTOMY AND OPEN MICROSURGICAL DISCECTOMY FOR LUMBAR DISC HERNIATION

Objectives. To estimate efficiency, safety and traumatizing impact of endoscopic discectomy in comparison with traditional microsurgical discectomy. Material and methods. A total of 330 patients underwent Destandau endoscopic discectomy and 964 – open microsurgical discectomy. The operative times, terms of patient postoperative bed and hospital stays, postoperative dynamics of neurologic deficiency, surgical complications and frequency of herniation recurrences were estimated in both groups. Pain intensity was assessed with the 10-score Visual Analog Scale (VAS), and functional activity – with the Oswestry Disability Index (ODI). Results of surgical treatment were estimated in 8–10 days, 6 and 12 months after operation. Results. VAS and ODI data have not revealed essential distinctions in pain regression dynamics after endoscopic and open surgeries. Surgical complications after endoscopic intervention were not more often, than after microsurgical discectomy. Damage of dura mater occurred in 2.4 % of cases, and increase in neurologic deficiency (hypoesthesia) – in 0.6 %. Herniation recurrences have evolved in 3.0 % of cases after endoscopic discectomy and in 4.7 % – after open microsurgical one. Conclusion. Destandau endoscopic surgery is a low invasive method of effective treatment for lumbar disc herniations, which by its technical opportunities and results is competitive with classical open microsurgical discectomy.
