By reviewing various literatures on endoscopic surgery for lumbar spinal stenosis and systematically analyzing the contraindications and complications of endoscopic surgery, the purpose of this study is to distinguish appropriate indications and contraindications for endoscopic surgery, and to predict the prognosis for the incidence of complications. We searched the PubMed databases to identify articles on endoscopic surgery for lumbar spinal stenosis. Preoperative exclusion criteria were included in contraindication, and complications that occurred during and after surgery were included. We analyzed clinical outcomes and classified the prescribed contraindication and complications according to the paper. We identified 120 articles, and 48 met our criteria, with evidence ranging from level I to level IV. After reviewing the literature, the analysis result, Contraindication of full endoscopic lumbar decompression are spondylolisthesis (>grade 2), instability, previous surgery, tumor (metastasis), infection, scoliosis, mainly back pain, painless weakness, cauda equine syndrome, etc. Complications of full endoscopic lumbar decompression are dura tearing, epidural hematoma, transient dysesthesia, untreated pain, motor weakness, cauda equine syndrome, incomplete decompression, etc. Fully endoscopic lumbar decompression is a safe, effective option for treating lumbar spinal stenosis, owever, it is important to select the surgical indication well, and various complications may occur after surgery.
