- Abstract
- Objects Percutaneous endoscopic transforaminal discectomy is often used as a minimally invasive procedure for lumbar disc herniation. To evaluate the efficacy of endoscopic discectomy for recurrent disc herniation and to determine the prognostic factors affecting surgical outcomes
Patients and Methods The inclusion criteria were recurrent disc herniation at the same level, regardless of side with a pain-free interval longer than 3 months after conventional open discectomy. During from January 2005 to March 2006, Percutaneous transforaminal endoscopic discectomy were performed in 8 patients who satisfied our inclusion criteria under local anesthesisa. We retrospectively evaluated the 8 cases with more than 6 months of follow up. The patients were evaluated using visual analogue scale (VAS).
Results The mean follow-up period was 8 months ( 5-16 months). Based on the Macnap criteria, 7 cases showed excellent or good outcomes. The mean visual analogue scale(VAS) decreased from 8.7 to 2.4.
Conclusions Percutaneous endoscopic lumbar discectomy is effective for recurrent disc herniation in selected cases. The transforaminal approach through unscarred virgin tissue can prevent nerve injury and could preserve spinal stability.
