Abstract
AIM: Prospective evaluation of the results of endoscopic lumbar discectomy.METHODS: 95 patients were consecutively enrolled in the study between 2017 and 2021. We monitored low back pain and sciatica according to the Visual Analogue Scale (VAS), the limitations in daily activities (Oswestry Disability Index, ODI), overall satisfaction according to a 0-100 % scale, and the rate of surgical complications and reoperations.RESULTS: Postoperatively, the VAS values of low back pain and sciatica decreased significantly from 5 to 1 point and from 6 to 1 point, respectively, and the pain remained in the tolerable range (VAS 1-2) throughout the follow-up period.
The ODI score improved significantly from severe disability (46 %), preoperatively, to moderate disability at discharge and one month after surgery (29 % and 22 %, respectively), down to minimal disability at 3 and 12 months after surgery (12 % and 14 %, respectively). Overall patient satisfaction improved significantly at all follow-up time points (46 %, 70 %, 77 %, 80 %, and 78 %, respectively).
Reoperation rate was 6.3 %. Cerebrospinal fluid leakage was observed in one case only (1.1 %).
Transient postoperative perianogenital sensory impairment occurred in two patients (2.1 %). There was no evidence of surgical site infection or haematoma.CONCLUSION: Endoscopic discectomy provides significant pain relief and improves the patient's ability to perform activities of daily living, contributing to greater satisfaction.
It is a safe method with a low risk of surgical and neurological complications (Tab. 3, Fig. 3, Ref. 27). Text in PDF www.elis.sk
