The aim of this study was to systematically review the efficacy of percutaneous transforaminal endoscopic discectomy (PTED) and fenestration discectomy (FD) in the treatment of lumbar disc herniation (LDH). ⋯ The Percutaneous transforaminal endoscopic discectomy is associated with better postoperative ODI score, better results in length of incision, lower blood loss, shorter operation time, postoperative bed time and hospitalization time. The complications did not differ significantly between PTED and FD in the treatment of lumbar disc herniation. These findings provide evidence to support PTED is efficacious for LDH; however, scar repair of a ruptured anulus fibrosus needs a long time and the patients undergoing PTED should be advised to stay in bed for a long time even if the symptoms are markedly relieved. These results are not limited to randomized controlled trials and lack data about the long-term outcome.
