Comparative analysis of unilateral biportal endoscopy and percutaneous endoscopic lumbar discectomy in the treatment of lumbar disc herniation
Objective To compare the clinical efficacies of unilateral biportal endoscopy(UBE)technique and percutaneous endoscopic lumbar discectomy(PELD)technique in the treatment of lumbar disc herniation.Methods The clinical data of 149 patients with lumbar disc herniation in our hospital were retrospectively analyzed and divided into the UBE group(n=80)and the PELD group(n=69)according to different surgical methods.The operation time,intraoperative fluoroscopy frequency,intraoperative blood loss,hospital stay,postoperative complications,visual analogue scale(VAS)score,Oswestry disability index(ODI)score,intervertebral disc height and vertebral canal area of the two groups were compared.Results The operation time in the UBE group was longer than that in the PELD group,and the intraoperative fluoroscopy frequency was fewer than that in the PELD group,the differences were statistically significant(P<0.001).There was no significant difference in the intraoperative blood loss or hospital stay between the two groups(P>0.05).There was no significant difference in the VAS or ODI scores at each time point between the two groups(P>0.05).There was no significant difference in the intervertebral disc height or vertebral canal area at each time point between the two groups(P>0.05).The postoperative vertebral canal areas of patients in the two groups were greater than those before surgery,and the differences were statistically significant(P<0.05).The incidence of postoperative complications in the UBE group was lower than that in the PELD group,the difference was statistically significant(P<0.05).Conclusion In terms of short-term efficacy,both PELD technique and UBE technique can effectively relieve the symptoms of low back and leg pain caused by lumbar disc herniation,and the UBE technique has longer operation time,but with fewer intraoperative fluoroscopy frequency,and lower incidence of postoperative complications.
