The goal of this clinical trial is to compare efficacy and safety of Mediclore as anti-adhesion agent in patient who undergo endoscopic lumbar discectomy. The main question[s] it aims to answer are:
Researchers will compare to see if experimental group have better patient-reported outcomes (PROs) after surgery with no different in complications rate.
This study is a randomized clinical trial arrange in King Chulalongkorn Memorial Hospital. Participant will be randomly assigned into 2 groups by computer-generated sequence. Patients based-line characteristic data, patient-reported outcomes (VAS back/leg, ODI and EQ-5D) and a results of straight leg raising test will be collected. Participant will undergo a endoscopic lumbar discectomy by a singer spine surgeon. In experimental group, 1.5 CC. of Mediclore (poloxamer-based thermosensitive anti-adhesive agent) will be applied in after finish the operation. In control group normal saline 1.5 CC. will be applied instead.
Participants will proceed to regular follow-up protocol which include 1, 3 and 6 months visit at out-patient department. All of the PROs and a result of a straight leg raising test will be collected at each visit. MRI will be performed at 3 month after the surgery. The amount of epidural fibrosis will be evaluated according to Ross's method.

| Visual Analogue Score for Leg pain (VAS Leg) | The VAS Leg consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('the worst pain in a lifetime'). The patient was asked to rate their current pain level by pointing the mark on the line. | 3 month after surgery |

| Visual Analogue Score for Leg and Back pain (VAS Leg, Back) | The VAS Leg and Back consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('the worst pain in a lifetime'). The patient was asked to rate their current pain level by pointing the mark on the line. | 1, 3 and 6 month after surgery (for VAS Back) and 1 and 6 month after surgery (for VAS Leg) |

| Normal Saline | Drug | After finish the operation, Control group will be applied 1.5 CC of normal saline at the surgical site. |

| Oswestry Disability Index (ODI) | The ODI consists of 10 questions to assess the function in daily activities living, in which the responses are presented as 6-point Likert scales. Scores range from 0% (no disability) to 100% (most severe disability). | 1, 3 and 6 month after surgery |
| EQ-5D-5L | The EQ-5D-5L has 2 parts. In the first part, consist of 5 questions to assess the function in daily activities living, in which the responses are presented as 5 level (1 means no problems to 5 means extreme problems). The digits for the five questions can be combined into a 5-digit number that describes the patient's health state. The results will interpreted with the country specific utility score (Thailand) and reported as three decimal digit range from 0 (the worst health you can imagine) to 1 (the best health you can imagine). | 1, 3 and 6 month after surgery |
| Epidural Fibrosis | Evaluation of epidural fibrosis by method proposed by Ross et al (1999) by MRI. From MRI axial cut, A surgical intervertebral level will be marked as level 3, 2 adjacent cephalic image will be marked as level 1 and 2. 2 adjacent caudad level will be marked as level 4 and 5. Then each image will be separated into 4 quadrant. Fibrosis will be graded on a scale of 0-4 for each quadrant at each imaging slice encompassing the operative level: 0 = no/trace scar; 1 = > 0-25% of quadrant filled with scar; 2 = 25-50% of quadrant filled with scar; 3 = 50-75% of quadrant filled with scar; 4 = > 75% of quadrant filled with scar. The highest grade of epidural fibrosis from any image will represent the degree of epidural ficrosis. | 3 month after surgery |
| Complication rate | peri-operation, 1, 3 and 6 month after surgery |
| Straight leg raising test | Straight leg raising test will be performed at each visit. Results will be recorded as negative or positive. If positive, the degree that make a test positive will be also recorded. | 1, 3 and 6 month after surgery |
