Increasing reoperation rates and inferior outcome with prolonged symptom duration in lumbar disc herniation surgery - A prospective cohort study
The Spine Journal Apr 14, 2019
Stottrup CC, et al. - The relationship between prolonged symptom duration and less favorable outcome following surgery for lumbar disc herniation (LDH) was evaluated in 2144 participants with a reoperation rate of 8.4% in a single-center, multi-surgeon, tertiary spine practice. They noted a higher incidence of surgical complications (specially dural tears) with a statistically insignificant increase in the duration of leg pain. One year after surgery, they recorded prolonged preoperative symptoms adversely impacting all patient-reported outcomes (PROs) ie, EuroQol-5D (EQ-5D), Oswestry Disability Index (ODI), and Visual Analog Scale (VAS). With longer duration of preoperative symptoms, they noticed an incline in the reoperation rates. They found a statistically significant inclination of an increasing incidence of reoperation with an increase in the length of symptom duration. A significantly better outcome was concluded in subjects who had surgery within the first 3 months of leg pain one year after surgery when compared to the other groups.
