Long-Term Results of Endoscopic Lumbar Discectomy by "Destandau's Technique".
METHODS
Prospective study.


OBJECTIVE
The aim of the study was to present long-term results from a 10-year follow-up after endoscopic lumbar discectomy (ELD) by "Destandau's technique".


BACKGROUND
Endoscopic disc surgery by Destandau's technique using ENDOSPINE Karl Storz system is a relatively new technique. It was introduced in 1993. It has been gaining popularity among the spine surgeons, as it is attractive for small skin incision and allows a gentle and excellent tissue dissection with excellent visualization. Many authors have published results of their own studies; however, in all these studies the long-term follow up of the patients has not been emphasized.


METHODS
A total of 21 patients selected on basis of strict inclusion criteria's underwent ELD from November 2004 to March 2005. Surgery outcome was assessed by using "Prolo's Anatomic-Functional-Economic Rating System" (1986). Patients were followed up to 10 years. In addtion, we compared the results of our study with other studies.


RESULTS
Outcomes were excellent in 17 patients (80.95%), good in 3 (14.28%) and fair in 1 (4.78%), with no patients having a poor result. In our study, 19 patients (90.47%) were able to resume their previous works/jobs, and only 2 (9.52%) needed to change their jobs for lighter work. No patient retired from his or her previous daily routine following the operation.


CONCLUSIONS
The initial and long-term results are very good for endoscopic lumbar discectomy by Destandau's technique. In properly selected patients it is a safe and minimally invasive technique, and we recommend ELD in properly selected patients.
