STUDY DESIGN
Prospective, randomized, controlled study of patients with lumbar disc herniations, operated full-endoscopic or microsurgical technique.


OBJECTIVE
Comparison of results of lumbar discectomies in full-endoscopic technique (interlaminar, transforaminal)  with the conventional microsurgical technique.


SUMMARY OF BACKGROUND DATA
-Even with good results, conventional disc operations may result in subsequent damage due to trauma.
-Endoscopic techniques have become the standard in many areas because of the advantages they offer intraoperatively and after surgery.
-With the transforaminal and interlaminar techniques, 2 full-endoscopic procedures are available for lumbar disc operations.


METHODS
Subject number: 178 patients (with full-endoscopic or microsurgical discectomy underwent follow-up for 2 years)
Measuring instruments: VAS, German version North American Spine Society Instrument, Oswestry Low-Back Pain Disability Questionnaire.


RESULTS
Postoperative pain: 82% of the patients no longer had leg pain/ 14% had occasional pain
Clinical results: same in both groups.
Recurrence rate: 6.2% (no difference between the groups)
-Full-endoscopic techniques have significant advantages in back pain, rehabilitation, complications, traumatization.


CONCLUSION
-The clinical results of the full-endoscopic technique are equal to those of the microsurgical technique. -There are advantages in the operation technique and reduced traumatization.

-Full-endoscopic surgery is a sufficient and safe supplementation and alternative to microsurgical procedures.
