Follow-up results of microendoscopic discectomy compared to day surgery using percutaneous endoscopic lumbar discectomy for the treatment of lumbar disc herniation

Abstract Background Percutaneous endoscopic lumbar discectomy (PELD) is satisfactory for hospitalized patients with disc herniation (LDH). Currently, only a few studies have reported about the day surgery undergoing PELD. Methods A total of 267 LDH underwent PELD during and were followed up at least 3 years. Clinical outcomes assessed using visual analog scale (VAS) leg lower back pain (VAS-B VAS-L, respectively) Oswestry disability index (ODI). The radiological outcomes, such as lordosis (LL), sacral slope (SS), disc-height ratio, instability, recorded compared. clinical effects between treated by microendoscopic (MED) contemporaneous 116 Results Patients had blood loss shorter hospital stay ( P < 0.001) compared to those MED. VAS-B, ODI decreased significantly after than before operation years postoperatively. postoperative VAS-B in group was MED = 0.001). complications rate 9.4% 12.1% 0.471). 1-year recurrence much higher that 0.042). LL SS improved values According ratio 3-year follow-up, significant height observed 0.014). Conclusions Although relatively high, advantages terms less intraoperatively, short stay, efficacy pain, efficiency maintain physiological curvature.
