BACK SURGERY! anyone heard of a Disk Excision? orthapedic surgeon wants to knife me...?

my orthapedic pain mgt doc has taken a look at my L5 S1 discs and found the protrusion thats compressing on the nerves/thecal sac thats causing me huge amounts of pain. they also found the cervical c1, c2, c3, c4, 5, 6, 7, 8 etc are effected as well. the condition according to the doc is called stenosis and herniated discs. the main herniation in l5 s1 is causing extreme shooting pain....so heres the deal, this orthopedic whom is a very unhappy camper it seems has asked me if i wanted to have a DISC EXCISION PROCEDURE..... the procedure he says will involve cutting away a part of the disc thats bulging out and eliminate the disc pressure on the nerves.... HAS ANYONE HAD A DISC EXCISION? this guys is an orthopedic and has been a doc since 1974.... to him i ume being an orthopedic makes him want to cut everything? there are lots of doctors that offer some much less invasive procedures with lasers that remove those disc problems etc.. i have read up on these docs that have much more innovative procedures, laser surgery etc... the laser surgery appears to be much more sensible as its miminally invasive, quicker recovery and less pain? does anyone have any input on my situation? lasier vs ortho knife? or have you yourself had success with a particular procedure? taking 120 mgs a day of percocet gets old... im looking for solutions... thank you!
