Brief Summary

PEN(percutaneous epidural neuroplasty) can be performed percutaneously, may be manipulated to mechanically break up adhesions by catheter, while various agents, such as anesthetics, corticosteroids, hyaluronidase, and hypertonic saline are injected. In endoscopic epidural neuroplasty (EEN), a flexible catheter is inserted into the sacral hiatus to precisely place the injection in the epidural space and onto the nerve root. Both EEN and PEN can eliminate the deleterious effects of scar formation, which can physically prevent the direct application of drugs to the nerves, and may provide pain relief in patients who have not responded to epidural blocks, physical therapy, or medication. In this study, visual analog scale (VAS) and Oswestry disability index (ODI) of patients with low back and radicular pain were compared in patients who had received EEN or PEN at 1 day, 1 month, and 6 months after EEN or PEN.

Study Arms (2)

Percutaneous epidural neuroplasty (PEN) group

Patients over 20 years of age with radiating pain in the lower back and legs who received PEN in patients who did not respond to medication and epidural nerve block treatment.

Procedure: Percutaneous epidural neuroplasty (PEN)

Endoscopic epidural neuroplasty (EEN) group

Patients over 20 years of age with radiating pain in the lower back and legs who received EEN in patients who did not respond to medication and epidural nerve block treatment.

Procedure: Endoscopic epidural neuroplasty

Interventions

EEN catheter, iDolphine S2 (Meta Biomed Co., Ltd, Osong, Korea) was placed in the epidural space through sacral hiatus. EEN was done on the target segments. During EEN, normal saline was infused into epidural space under epiduroscopic vision. Dexamethasone (5 mg), 0.3% mepivacaine 10 mL, and hyaluronidase (3000 IU) were injected through catheter at the target segments. Holmium-Yag laser was used to cut epidural fibrous bands and for coagulation of epidural bleeding.

Also known as: Percutaneous epidural neuroplasty (PEN)
Endoscopic epidural neuroplasty (EEN) group

PEN catheter, EDEN-CC (JMT, Yangju, Korea) was placed in the epidural space and neural foramen . PEN was done on the target segments. Dexamethasone (5 mg), 0.3% mepivacaine 10 ml, and hyaluronidase (3000 IU) were injected through the PEN catheter.
