Delta large-channel endoscopy versus unilateral biportal endoscopy decompressive laminectomy for lumbar spinal stenosis: a prospective randomized controlled trial
Abstract Background Delta large-channel endoscopy and unilateral biportal endoscopy (UBE) are prominent minimally invasive techniques for treating lumbar spinal stenosis, known for minimal tissue damage, clear visualization, and quick recovery. However, rigorous controlled research comparing these p...

| description | Abstract Background Delta large-channel endoscopy and unilateral biportal endoscopy (UBE) are prominent minimally invasive techniques for treating lumbar spinal stenosis, known for minimal tissue damage, clear visualization, and quick recovery. However, rigorous controlled research comparing these procedures is scarce, necessitating further investigation into their respective complications and long-term effectiveness. This randomized controlled trial aims to compare their perioperative outcomes, focusing on postoperative recovery and complications over time. Methods In total, 101 participants were randomly assigned to Delta large-channel endoscopy group (n = 50) or UBE group (n = 51). Primary measures were Oswestry Disability Index (ODI) scores and operation time. Secondary measures included VAS, EQ-5D, JOA scores, intraoperative blood loss, hospital stay duration, and costs. Perioperative complications such as dural tears, incision infections, hematomas, thrombosis, and reoperation rates were recorded. Results The Delta group consistently showed lower mean ODI scores throughout the follow-up than UBE group, with significant differences at 2 weeks postoperative (P = 0.048), though they were not significant by 1 month (P = 0.124), 2 months (P = 0.821) and 3 months (P = 0.350). Operation times were shorter in the Delta group (P < 0.001). Hospitalization costs and intraoperative blood loss were slightly higher in the UBE group (P < 0.001). No significant differences were noted in the other secondary outcomes at various post-surgery intervals, such as VAS, EQ-5D, JOA scores, hospital stay duration and complications. Conclusion Both techniques are safe and effective when performed by experienced surgeons. Compared to UBE, Delta large-channel endoscopy can shorten surgery time and reduce blood loss, and more importantly, it promotes faster recovery of lumbar function in the early postoperative period.
