Unilateral Biportal Endoscopic Discectomy and Percutaneous Endoscopic Interlaminar Discectomy in Lumbar Disc Herniation:a Comparative Study
Objective To compare clinical efficacy between percutaneous endoscopic interlaminar discectomy(PEID)and percutaneous bilateral endoscopic lumbar discectomy(UBED)in treatment of patients with lumbar disc herniation(LDH).Methods Data were collected on 103 LDH patients treated with PEID and UBED,78 in the PEID group and 25 in the UBED group.The patients in both groups were followed up for 3 months after surgery.Intraoperative indicators(intraoperative blood loss,operation time,intraoperative fluoroscopy frequency,ambulation time,hospitalization time,and surgical complications)and clinical outcome indicators at different time points[visual analogue scale(VAS)and Oswestry disability index(ODI)preoperatively,3 days postoperatively,and 3 months postoperatively]were compared between the 2 groups.Results In the PEID group,there was 1 case of nerve root injury,but postoperative follow-up showed relief of nerve root symptoms and lower back and leg pain symptoms.Intraoperative blood loss in the PEID group was significantly less than that in the UBED group(P＜0.05).At 3 days and 3 months postoperatively,VAS scores and ODI in both groups were significantly improved compared to preoperative levels(both P＜0.01).There were no statistically significant differences in operation time,intraoperative fluoroscopy frequency,ambulation time,and hospitalization time between the 2 groups(P＞0.05).Conclusion These findings provide evidence that both PEID and UBED demonstrate positive clinical efficacy in the management of LDH,with less intraoperative bleeding in PEID and more complete decompression and lower risk of nerve damage in UBE
