Background and Objectives : Minimal invasive lumbar discectomy(MID) such as Percutaneous endoscopic lumbar discectomy have promoted as an alternative to conventional discectomy. The PELD may be less injury to muscle, decreased postoperative pain, and faster recovery time. However, recurrence after lumbar disc operation could not be prevented. Accordingly we compared with both lumbar discectomy technique these are endoscopic discectomy and microscopic discectomy about postoperative recurrent rate.

Materials and Methods : We porformed retrospective controlled randomized study from January 2008 to April 2014. One hundred sixty-two patients underwent endoscopic discectomy or microsurgical open discectomy for lumbar disc herniation during seven years by one single surgeon. Inclusion criteria were disc herniation at the one single level, regardless of side. The relationship of several factor(Age, sex, operation technique, operation level) and recurrent rate were evaluated.

Results : Age, sex, and operation level were not statistically significant difference about recurrent rate. Especially operation technique such as endoscopic discectomy or microscopic open discectomy were not statistically significant difference for recurrent rate.

Conclusion : These parameters that we checked are all no statistically significant difference. And recurrent rate are not related with one side of operation technique. The cause of postoperative recurrence has been unknown.

Key word : Discectomy, PELD, Recurrence
