Clinical Trial Summary

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:

• efficacy (patient-reported outcomes, epidural fibrosis)

• safety (complications) Participants will received Mediclore at surgical site after finish the operation in experimental group and normal saline in control group.

Researchers will compare to see if experimental group have better patient-reported outcomes (PROs) after surgery with no different in complications rate.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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
Secondary	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)
Secondary	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
Secondary	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
Secondary	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
Secondary	Complication rate		peri-operation, 1, 3 and 6 month after surgery
Secondary	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
