  • Comparative analysis of unilateral biportal endoscopic discectomy, percutaneous endoscopic lumbar discectomy, and fenestration discectomy in treatment of lumbar disc herniation

    Objective To investigate the effectiveness of unilateral biportal endoscopic discectomy (UBED), percutaneous endoscopic lumbar discectomy (PELD), and traditional fenestration discectomy (FD) in the treatment of lumbar disc herniation (LDH). Methods The clinical data of 347 LDH patients who met the selection criteria and underwent discectomy between January 2017 and December 2021 were retrospectively analyzed. They were divided into FD group (160 cases), PELD group (86 cases), and UBED group (101 cases) according to operation methods. There was no significant difference in gender, age, surgical level distribution, disease duration, and preoperative visual analogue scale (VAS) score and Oswestry disability index (ODI) between groups (P>0.05). The operation time, hospitalization stay, treatment cost, and incidence of surgery-related complications were recorded and compared between groups. The patients’ pain and functional recovery were evaluated by VAS score and ODI before and after operation. Results The operation time of FD group was significantly shorter than that of PELD group and UBED group, and the hospitalization stay was significantly longer than that of PELD group and UBED group (P<0.05); there was no significant difference between PELD group and UBED group (P>0.05). The treatment cost in UBED group was significantly higher than that in PELD group, and in PELD group than in FD group (P<0.05). All the patients were followed up 6-24 months, with an average of 14.6 months. VAS score of lower extremity and ODI in 3 groups significantly improved after operation when compared with that before operation (P<0.05). At 1 day after operation, VAS score of lower extremity of UBED group was significantly better than that in PELD group and FD group (P<0.05), but there was no significant difference between PELD group and FD group (P>0.05). There was no significant difference in VAS scores of lower extremity between the 3 groups at 1 and 3 months after operation (P>0.05). The difference of ODI before and after operation in FD group and UBED group was slightly better than that in PELD group (P<0.05), and there was no significant difference between FD group and UBED group (P>0.05). Incidence of surgery-related complications in FD group (20.0%) was significantly higher than that in PELD group (12.8%) and UBED group (6.9%), and PELD group was significantly higher than UBED group (P<0.05). All the incision infection occurred in FD group (12 cases), symptomatic disc cyst and myeloid hypertension-like occurred in 1 case each in PELD group.Conclusion UBED, PELD, and FD have similar effectiveness on lower extremity pain in early LDH. Compared with FD, UBED and PELD have the advantage of shorter hospitalization stay and fewer complications.
