ABSTRACT
Background:
As the latest endoscopic
spine surgery, percutaneous endoscopic interlaminar
discectomy (PEID) and unilateral biportal endoscopic (UBE)
discectomy have distinct technical characteristics. This study aimed to evaluate the clinical outcomes of PEID and UBE
discectomy in the
treatment of single-level lumbar
disc herniation (LDH).
Methods:
Between February 2019 and April 2022, 115
patients with single-level LDH at L4-5 or L5-S1 received PEID or UBE
discectomy. The
patients were
separated into two groups based on the surgical
method used Group 1 (the PEID group) (n = 60) and Group 2 (the UBE group) (n = 55). Various
parameters, including
operative time,
hospitalization time,
fluoroscopy frequency, total
costs,
complications, visual analogue scale (VAS), and Oswestry Disability Index (ODI), were evaluated and compared between the two groups.
Results:
There were no significant differences in the VAS and ODI scores in 12 months after the operation between two groups (P > 0.05). However, the VAS of
lower back pain on the first day after the operation in Group 2 (2.53±0.89) was higher than that in Group 1 (2.19±0.74) (P < 0.05). There were no significant differences in the operation
time and
incidence of
complications between two groups (P > 0.05). But total
costs in Group 2 (43,121±4280) were significantly higher than those in Group 1 (30,069±3551) (P < 0.05).
Conclusion:
Both UBE and PEID
procedures have
similar efficacy in alleviating
pain and improving functional
ability in
patients with LDH. However, UBE
surgery results in higher
costs than PEID
surgery.
