The effect of percutaneous transforaminal endoscopic discectomy (PTED) on serum inflammatory factors and pain in patients with lumbar disc herniation after surgery

Objective: The study aims to investigate the effect of PTED on serum inflammatory factors and pain in patients with lumbar disc herniation. Methods: 94 patients with lumbar disc herniation treated in our hospital were enrolled in this study. Patients were randomly divided into group A (n=47) and group B (n=47). Group A were treated with fenestration discectomy, and Group B were treated with PTED discectomy. The general clinical data, the duration of surgery, bleeding amount, the length of hospital stay, and the complications of patients were compared between two groups. The serum level of TNF-a and IL-6 was detected by enzyme-linked immunosorbent assay (ELISA), and the visual an-alogue score (VAS) between group A and group B was compared by Japanese Orthopaedic Association Scores (JOA). Results: The total duration of surgery, total bleeding amount, and length of hospital stay in group B were less or shorter than those in group A (P
