"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."

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.
