Any endoscopic discectomy comments for 8mm fragment on nerve at L3?

If I lift my right leg or do too much sitting or exercising, I have pain running from my hip down to my knee caused by the disc fragment. With a "regular" discectomy, the spinal surgeon can only see 50% of the disc fragment which means spinal shaving and fusing perhaps making symptoms worse. To avoid that, endoscopic discectomy was recommended. Any comments or results from folks that had this relatively new procedure done to remove a fragment at L3-5?
