Health-related quality of life (HRQoL) following transforaminal percutaneous endoscopic discectomy (TPED) for lumbar disc herniation: A prospective cohort study – early results

Abstract

BACKGROUND:

Lumbar discectomy is among the most frequently performed procedures in spinal surgery. Transforaminal percutaneous endoscopic discectomy (TPED) is a minimally invasive technique that gains ground among surgeons in the recent years. TPED has been studied in terms of effectiveness, however little is known about its overall impact on health-related quality of life (HRQoL) of the patients.

OBJECTIVE:

To investigate the progress of HRQoL following TPED.

PATIENTS AND METHODS:

Seventy-six (76) patients were enrolled in the study. Mean age was 56.5 $\pm$ 12.1 years with 38 (50%) males and 38 (50%) females. All patients underwent TPED at L3-L4 (27.6%), L4-L5 (52.6%) and L5-S1 (19.7%). SF-36 was used for the assessment of HRQoL preoperatively and at 6 weeks, at 3, 6 and 12 months after the procedure.

RESULTS:

All aspects of SF-36 questionnaire showed statistically significant improvement one year after the procedure ( $p<$ 0.001). Role limitations due to physical problems, bodily pain and role limitations due emotional problems showed the highest improvement, followed by physical functioning, vitality, social functioning, mental health and general health.

CONCLUSIONS:

TPED for lumbar disc herniation is associated with significant improvement in all aspects of health-related quality of life within 6 weeks postoperatively and the improvement remains significant one year after surgery, as measured by the SF-36 questionnaire.
