Percutaneous Endoscopic Lumbar Discectomy is a one night stay surgery with a 7 mm incision under local anesthesia. We discuss 3 methods and each indication for 197 herniations from April 2007 to March 2008. The average age was 48.8 years old, 136 men, 61 women. They were 112 transforaminal approaches from L2/3 to L5/S1, 64 interlaminar approaches for L5/S1 with high iliac crest and 21 extraforaminal approaches for lateral herniations. The migration over more than 1cm, instability, lateral recess less than 3mm and osseous proliferation were excluded. JOA score was 11.1 preoperatively, 20.5 (1 month later), 22.2(3M), and 22.0(6M). VAS of buttock and legs pain were 7.2 preoperatively, 2.1(1M), 1.6(3M), 1.5(6M later). 16 revision operations(8%) were for 1 level mistook case, 1 unclear view due to bleeding, 1 decreased blood pressure, 2 impossible insertions, 4 remnants, 4 recurrences and 3 adhesions of post-operation.
