Article Abstract
Lumbar decompressive surgery is the gold standard treatment for lumbar spinal stenosis. Minimally invasive surgical techniques have been introduced with the aim of reducing the morbidity associated with open surgery. The purpose of the present study was to systematically search the literature and perform a meta-analysis of studies comparing the outcomes between biportal endoscopic technique and microscopic technique for lumbar canal stenosis decompression. A comprehensive search of the PubMed, Google Scholar, Web of Science, Embase and the Cochrane Library databases was performed to identify relevant articles up to 15th of December 2019. Eligible studies were retrieved, data were extracted by two authors independently and risks of bias were assessed. A total of six studies involving 438 patients were selected for review. The results of the pooled analysis indicated similar operative times [mean difference (MD), -3.41; 95% CI, -10.78-3.96; P<0.36], similar complications (MD, 0.70; 95% CI, 0.33-1.46; P=0.34), similar visual analogue scale scores for back and leg pain at the time of the final follow-up and similar Oswestry disability indexes (MD, -0.28; 95% CI, -1.25-0.69; P=0.58) for the two procedures. In conclusion, biportal endoscopic technique is a viable alternative to microscopic technique for lumbar canal stenosis decompression with similar operative time, clinical outcomes and complications.

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.

Background: This study aimed to compare a 3-dimensional (3D)-printed titanium cage with a polyetheretherketone (PEEK) cage in biportal endoscopic transforaminal lumbar interbody fusion (BETLIF) using a double cage construct, evaluate differences in fusion stability and subsidence between the 2 cage types, and analyze factors influencing subsidence.
Methods: We retrospectively examined 89 patients who underwent BETLIF using a double cage (3D-printed titanium, 48 levels; PEEK, 46 levels). Fusion status and subsidence were assessed using dynamic plain lateral lumbar spine radiographs and computed tomography images at 6 months and 1 year postoperatively.
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.

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.

Introduction: Full-endoscopic spinal surgery (monoportal endoscopy) has emerged as a minimally invasive alternative for managing intradural spinal pathologies, offering reduced morbidity and accelerated recovery compared to conventional techniques.
Research Question: What is the current evidence on the effectiveness, limitations, and future prospects of full-endoscopic spinal surgery for intradural pathologies?
Material And Methods: A systematic review following PRISMA guidelines was conducted. Electronic databases (Cochrane, OVID-MEDLINE, PubMed, Embase, Web of Science, Scopus) were searched for studies published from 2000 to 2024.
