Risk factors for postoperative complications after UBE surgery for thoracic spinal stenosis and construction of a nomogram predictive model.

Department of Mini-invasive Spinal Surgery, The Third People's Hospital of Henan Province, Zhengzhou, Henan, China.
Background: This study aimed to develop and validate the first nomogram model for predicting postoperative complications in thoracic spinal stenosis (TSS) patients undergoing unilateral biportal endoscopy (UBE), integrating multidimensional risk factors to provide a quantitative basis for preoperative risk evaluation and individualized treatment planning.
Methods: Patients were divided into a retrospective training cohort ( = 375) and a prospective validation cohort ( = 100). Baseline clinical data [age, diabetes, preoperative Japanese Orthopaedic Association (JOA) score], radiographic parameters (Spinal cord/canal area (SC/ECA) ratio, intramedullary high signal, thoracic kyphosis (TK) angle), and surgical variables (intraoperative blood loss, number of lesion segments, dural adhesion, etc.
Bilateral-Contralateral Endoscopic Decompression as a Fusion-Deferral Strategy in Upper Lumbar Stenosis: A Structural Rationale and Conditional Framework-A Technical Note with Cases Review.

Department of Neurosurgery, Spine Center, Nanoori Gangnam Hospital, Seoul 06048, Republic of Korea.
Upper lumbar spinal stenosis presents unique challenges because vertically oriented facet joints and narrow laminae increase the risk of iatrogenic instability following decompression. Traditional decompression techniques may damage the facet joints, potentially resulting in further instability and degeneration. This study introduces a novel, facet-preserving bilateral-contralateral decompression strategy using unilateral biportal endoscopy (UBE) for upper lumbar stenosis, aiming to defer unnecessary spinal fusion.

Background: Robotic-assisted unilateral biportal endoscopic surgery (UBE) is a more accurate and safer technique than traditional open surgical operations. The penetration recognition of ultrasonic drilling remains one of the challenging techniques of robotic-assisted UBE surgery.
Methods: We propose a force and VAE-MLP-based method for real-time penetration recognition.
THE EFFECT OF BLOOD PRESSURE VALUE ON INTRAOPERATİVE IMAGİNG İN BİPORTAL ENDOSCOPİC SPİNE SURGERY.

Ankara University Faculty of Medicine, Anaesthesiology and Reanimation Department, Ankara, sss.
Unlabelled: In unilateral biportal endoscopic (UBE) decompression surgery, image quality reduces potential risks in the surgical field and allows the surgical procedure to be performed in a shorter time. This study aimed to investigate the relationship between visualization and blood pressure during surgery and to determine the optimal blood pressure to maintain good visualization during surgery.
Material Method: A senior surgeon and an assistant surgeon independently evaluated intraoperative visualization during UBE entry, laminotomy, and foraminotomy.
