A retrospective, population-based, cohort study using Korean national health
insurance data was performed and 18,590 patients were followed for at least 5

The primary end-point was any type of second lumbar surgery.
After adjusting for confounding factors, five surgical methods (fusion,
laminectomy, open discectomy, endoscopic discectomy, and nucleolysis
[including mechanical nucleus decompression]) were compared.
The reoperation rate at 3 months was higher for laminectomy. Rates for the
other surgical methods were similar to that of open discectomy, during the
entire follow-up period.
