Professor Seung-Kook Kim's research lab specializes in minimally invasive spinal surgery, with a primary focus on endoscopic and percutaneous spinal interventions such as trans-sacral epiduroscopic laser decompression (SELD) and water-tight dural repair techniques. The lab investigates clinical outcomes, procedural safety, and long-term functional recovery in patients with lumbar disc herniation, comparing endoscopic approaches to traditional microscopic open discectomy. Research also emphasizes improving surgical instrumentation, including novel dural protectors and knot pushers, to enhance surgical efficacy and reduce complications. The lab's work contributes to advancing less invasive, patient-friendly spinal surgery with reduced recovery times and lower complication rates.

The novel dural protector and the knot pusher for water-tight sutures improved the efficacy and safety of decompression and discectomy; however, a prolonged operative time was a drawback.
Incomplete decompression, recurrent herniation, epidural hematoma, dural tear, and subchondral osteonecrosis were identified as complications of SELD, although the overall rate of complications was low. Practice with the procedure and careful patient selection can lower the risk of complications.
<b>Context/Objective:</b> Trans-sacral epiduroscopic laser decompression (SELD) is an alternative to microscopic open lumbar discectomy (OLD). SELD and OLD for L5-S1 lumbar disc herniation (LDH) have not been compared. We compared clinical results, including pain control, between SELD and OLD.<b>Design:</b> Retrospective analysis.<b>Setting:</b> Korean hospital.<b>Participants:</b> Eighty patients treated with SELD (n = 40) or microscopic OLD (n = 40) for L5-S1 LDH.<b>Interventions:</b> N/A.<b>O

A rare case of solitary diffuse large B-cell lymphoma arising from the lumbar spinal nerve root is reported. A 37-year-old man presented with a 3-month history of progressive numbness and paraparesis in both legs. The initial diagnosis was benign primary intradural extramedullary tumor including schwannoma and meningioma. Histopathological examination revealed diffuse large B-cell lymphoma. While a well-defined T1 isointense mass is common in primary spinal schwannoma, the present case was atypi
The reoperation rate, preoperative risk factors, reason for revision, reoperation type, clinical outcomes, patient satisfaction, and time interval between index and re-surgery were different between the primary fusion and primary decompression. A better understanding of disease pathophysiology and surgical procedure characteristics will facilitate improvement in disease management and the development of treatment strategies.
Stand-alone expandable cage fusion can restore local lordosis; however, global sagittal balance was not restored. Furthermore, implant safety has not yet been proven.
<i>Background and Objectives</i>: Symptomatic adjacent segment degeneration (ASD) with lumbar spinal canal stenosis (LSCS) is a common complication after spinal intervention, particularly interbody fusion. Stand-alone posterior expandable cages enable interbody fusion with preservation of the previous operation site, and screw-related complications are avoided. Thus, the aim of this study was to investigate the clinicoradiologic outcomes of stand-alone posterior expandable cages for ASD with LSC
