Re-Op Rates ID'd for Herniated Intervertebral Disc Disease
(HealthDay News) – For patients undergoing surgery for lumbar herniated intervertebral disc disease, reoperation rates reach 13.4% after five years, with more than half of reoperations occurring in the first year, according to a study published in the April 1 issue of Spine.
Chi Heon Kim, MD, PhD, from Seoul National University Hospital in the Republic of Korea, and colleagues conducted a retrospective cohort study using data from 18,590 patients identified from a national health insurance database to examine the longitudinal reoperation rate after surgery for lumbar herniated intervertebral disc disease. Patients were followed for ≥5 years.
The researchers found that the most common procedure was open discectomy (68.9%), followed by endoscopic discectomy, laminectomy, fusion, and nucleolysis (16.1%, 7.9%, 3.9%, and 3.1%, respectively). At three months, the cumulative reoperation rate was 5.4%, and at one, two, three, four, and five years, it was 7.4%, 9%, 10.5%, 12.1%, and 13.4%, respectively. The reoperation rate was 18.6% after laminectomy, 14.7% after nucleolysis, 13.8% after open discectomy, 12.4% after endoscopic discectomy, and 11.8% after fusion. At three months, the reoperation rates of all procedures except laminectomy were not significantly different to that of open discectomy.
"Here, for herniated intervertebral disc disease-related surgery, the cumulative reoperation rate during five years of follow-up was 13.4% with half of the reoperations occurring during the first postoperative year," the authors write. "Although our population-based data lacked detailed information, the results obtained may be useful to clinicians and patients."
