“…Favorable outcomes have been reported for spinal stenosis, extraforaminal disc herniation, and spondylolisthesis, as well as for discectomy for disc herniation in the lateral recess. [3][4][5][6][7] The most common complication of UBES is dural injury. Recent studies report an incidence rate of 1.9% to 5.8%.…”

Study Design: Retrospective study. Objectives: Unilateral biportal endoscopic surgery (UBES) is a popular surgical method used to treat degenerative spinal diseases because of its merits, such as reduced tissue damage and outstanding visual capacity. However, dural injury is the most common complication of UBES with an incidence rate of 1.9% to 5.8%. The purpose of this study was to analyze the pattern of dural injury during UBES and to report the clinical course. Methods: We retrospectively reviewed the medical and radiographic records of surgically treated patients who underwent UBES at a single institute between January 2018 and December 2019. Results: Fifty-three patients, representing 67 segments, underwent UBES. Seven dural injuries occurred, and the incidence rate was 13.2%. Among 16 far lateral approaches, 2 dural injuries of the exiting roots occurred and were treated with fibrin sealant reinforcement. Among 51 median approaches, dural injury occurred at the thecal sac (n = 3) and traversing root (n = 2). A dural injury of the shoulder of the traversing root was treated with a fibrin sealant; however, a defect in the thecal sac required a revision for reconstruction. The other 2 thecal sac injuries were directly repaired via microscopic surgery. Conclusions: Dural injury during UBES can occur because of the various anatomical features of the meningo-vertebral ligaments. Direct repair of the central dural defect should be considered under microscopic vision. A linear tear in the lateral dura or root can be controlled with a simple patchy reinforcement under endoscopic vision.

“…24,25,27,28 With recent advancements in endoscopic technology and surgical instruments, UBE techniques have been successfully applied to treat various disorders in the cervical, thoracic, and lumbar spines. [29][30][31] For DLCS, adequate decompression can be achieved with the UBE technique. Up to 200% increments in the cross-sectional dura area after operation have been reported.…”

Background: The unilateral biportal endoscopic (UBE) technique provides minimally invasive decompression for degenerative lumbar canal stenosis (DLCS). With appropriate control of the hydrostatic pressure of normal saline irrigation, the surgery can be performed in a clear and magnified surgical field through 2 small surgical wounds.Methods: A review of published literature in PubMed was performed to identify studies of UBE decompression for DLCS. The outcome measures include operation time, length of hospital stay, estimated blood loss, visual analog scale (VAS) scores for back and leg pain, Oswestry Disability Index (ODI), and the Macnab criteria.Results: A total of 76 relevant studies were retrieved through the PubMed search. After screening, 15 studies comprising 6 case series, 6 comparative studies, and 3 randomized controlled trials were included in this review. Significant improvements in pain and neurological symptoms were obtained in all studies. In the 6 case series studies, the outcome measures were extracted from each study and summarized. The follow-up periods ranged from 8.6 to 29 months. The operation time was 72.0 min. The VAS score for leg pain was reduced from 7.8 to 1.7, and the VAS score for back pain was reduced from 5.8 to 1.7. The ODI was reduced from 63.0 to 20.7, and 87.3% of patients reported good to excellent outcomes according to the Macnab criteria. The complication rates ranged from 5.5% to 13.8%, with dural tear having the highest incidence rate. In the comparative studies and randomized controlled trials examining the UBE, microscopic, microendoscopic, and uniportal endoscopic techniques, the UBE technique showed treatment results that were comparable with the others. Compared with the microscopic technique, the UBE technique resulted in significantly less tissue trauma and quicker recovery with less wound pain, lower serum creatine kinase and C-reactive protein levels, and lower ODI in the very early postoperative period. The UBE technique also provided adequate decompression with less facet joint destruction than all the other decompression techniques.Conclusions: The UBE technique is safe and effective for decompression of DLCS. Along with its efficacy in decompression, this technique is capable of preserving segmental stability. However, a long-term comparative study is required to verify this hypothesis.

“…Only by constantly strengthening medical exchanges with South Korea could we go further and further on the development of UBE/BESS technology research. Choi DJ, who had high academic influence, ranked first in the number of articles and focused on the exploration of UBE/BESS technology in South Korea [19][20][21][22][23][24] .…”

The study aimed to make a bibliometric analysis of the current research situation in unilateral biportal endoscopy/biportal endoscopic spinal surgery (UBE/BESS). Research data sets were acquired from the Web of Science database. The study chosed “biportal endoscopic spinal surgery” OR “two portal endoscopic spinal surgery” OR “percutaneous biportal endoscopic decompression” OR “unilateral biportal endoscopy” OR “irrigation endoscopic discectomy” as the search terms. The literature search was limited to articles published before March 5, 2021. We only included original articles and reviews. VOS viewer and Citespace software were used to analyze the data and generate visualization knowledge maps. Annual trend of publications, distribution, H‐index status, co‐authorship status, and research hotspots were analyzed. A total of 74 publications met the requirement. The sum number of citations was 31,204, in which 19,336 were no self‐citations. The average citation of all the papers was 21.84 times. The H‐index of all the publications was 85. South Korea's total number of articles was far higher than that of other countries and regions (61, 82.4%), followed by United Arab Emirates, Egypt, and Peoples Republic of China (three, ranking second, accounting for 12.2% of the total). For the most productive authors, Choi ranked first with 21 articles, Kim ranked second with 16 articles, and Heo ranked third with 12 articles. The journal with the greatest number of publications was World Neurosurgery, with a total of 18 (39.1%) papers. Clinics in Orthopedic Surgery ranked second with six (13.0%) papers. In third place, there were fix articles published by Asian Spine Journal and Neurospine, accounting for 21.8% of the total articles. These top three journals accounted for 73.9% of all the papers. Spondylolisthesis and endoscopic decompression were the research hotspots in recent years. The number of publications has showed an upward trend with a stable rise in recent years. South Korea is the country with the highest productivity, not only in quality, but also in quantity. Barun Hosp and Leon Wiltse Mem Hosphave published most articles. Choi is the most productive author. World Neurosurgery is the most productive journal. Spondylolisthesis and endoscopic decompression are the research hotspots in recent years. Indeed, this study provides new insight into the growth and development of UBE/BESS.
