Percutaneous Endoscopic Lumbar Discectomy: Indications and Complications

摘要

Background: Percutaneous endoscopic lumbar discectomy (PELD) often refers to percutaneousendoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminardiscectomy (PEID). As a minimally invasive spinal procedure, PELD has gained increasing recognitionfor its small incision, quick recovery, short hospital stay, and equivalent clinical outcome comparedto open surgery. In order to obtain satisfactory clinical efficacy, adequate consideration should begiven regarding the indication of PELD. On the other hand, complications related to PELD will alsosignificantly affect the safety and outcome of surgery.Objective: Our objective was to conduct a literature review of the indications and complicationsof PELD and to provide our experience in patient selection and solutions to complications relatedto PELD.Study Design: The study is a literature review focused on the indications and complications ofPELD.Setting: The study is a literature review on the indications and complications of PELD.Methods: A comprehensive review of available literature on PELD was performed. Particularfocus was given to the development of indications and prevention of complications. The literaturewas searched in PubMed database, and key words were set as “percutaneous endoscopic lumbardiscectomy”, “percutaneous endoscopic transforaminal discectomy”, “percutaneous endoscopicinterlaminar discectomy”, “PELD”, “PETD”, “PEID”, “YESS” and “TESSYS”.Results: PELD is an effective and safe treatment for lumbar disc herniation, lumbar spinal stenosis,recurrent lumbar disc herniation, and other lumbar diseases. Complications related to PELD includedural tear, nerve root injury, recurrence, and so on.Limitations: Some results drawn in this review are based on retrospective study or small samplesize. Studies of larger sample size and more multicenter, randomized controlled trials should beconducted to evaluate the clinical efficacy and safety of PELD.Conclusions: PELD is a promising surgical technique for lumbar diseases. Proper patient selection,excellent surgical skills, and rich experience are required for satisfactory outcomes.
