Lumbar disc herniation compressed the nerve cause pain, numbness, weak legs called sciatica, which seriously decrease the quality of life and work efficiency. Both collagenase chemonucleolysis(CCNL) and percutaneous endoscopic lumbar discectomy (PELD) was effective to treat lumbar disc herniation(LDH) requires surgery. whether functional clinical outcomes of CCNL vs PELD effect on LDH was superior, and no study provided convincing evidence.
Lumbar disc herniation (LDH) is a common disease with an incidence of 1%-3%, usually manifested as low back pain radiating to the lower extremities, which seriously affects patients' quality of life. Collagen hydrolysis was effective in treating LDH, it makes the protrusion smaller or disappeared, relieving or resolving the compression of nerve root by the protrusion.Percutaneous endoscopic lumbar discectomy (PELD) is a less invasive techniques to treat LDH. However, the outcomes of collagen hydrolysis vs PELD effect was still unknown.

Exclusion Criteria:
After local anesthesia, and the puncture point was 8-12cm on the side of the paraspinous process under C arm fluoroscopy. The needle was punctured though the skin with an angle of 45-60 to the posterior of the vertebral via "safe" entry zone to the herniated site outside the intervertebral disc under the epidural space. The syringe was drawn back to confirm that no blood or cerebrospinal fluid was flowing out, Contrast agents were injected to make sure no flows out of the spinal canal. 600 unit collagenase was dissolved in 2ml normal saline and injected slowly with rate of 1ml per minute. The needle was removed and keep the dorsal elevated position for 6-8 hours. Keep away from load bear of lumbar for 3 months.
Procedure: Collagenase chemonucleolysis
For L1-L4 segment, percutaneous endoscopic transforaminal discectomy(PETD) will be performed. An 1cm length incision was made at 8-14cm lateral of the paraspinous process, where a needle puncture to the superior articular process of the lower involved vertebrae of the herniated disc. A series of conical rods are to be introduced, subsequently a reamer is to be introduced through the cannula. After removal of the disc herniation, the cannula and endoscope are to be removed. For L5/S1 segment, percutaneous endoscopic interlaminar discectomy(PEID) was performed. An incision of nearly 7 mm was made at the entry point of the skin, and a series of expansion channels were sequentially inserted into the surface of the ligamentum flavum.Then, the ligamentum flavum and soft tissue around it were removed. Then, the tongue of the working cannula was inserted and rotated into the lateral nerve root. Removed the prominent nucleus pulposus by various nucleus pulposus forceps.

Visual Analogue Scale/Score of leg
Visual Analogue Scale pain assess for leg. Use a ruler about 10cm long, one side is marked with "0" and the other "10" respectively. A score of 0 indicates no pain, 10 indicates the most unbearable pain.
Time frame: up to 12 months
Visual Analogue Scale/Score of lumbar
Visual Analogue Scale pain assess for lumbar. Use a ruler about 10cm long, one side is marked with "0" and the other "10" respectively. A score of 0 indicates no pain, 10 indicates the most unbearable pain.
Time frame: up to 12 months
Recurrence rate
The percentage of disc herniation recurrence appearance. 0 represents the minimum and 100% represents the maximum.

The Roland-Morris Disability Questionnaire
The Roland-Morris Disability Questionnaire is a health status measure designed to be completed by patients to assess physical disability due to low back pain. The lowest score is 0, the highest 24. The higher the score, the more severe the dysfunction.
Time frame: up to 12 month
the EuroQoL-5D (EQ-5D)
EQ-5D descriptive system is a preference-based Health-related quality of life measure with one question for each of the five dimensions that include mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. From this, a quality of life score can be calculated ranging from -0.594, indicating a health state worse than death where 0 is death, to 1, indicating full health
