Summary
Reoperation rates after biportal endoscopic lumbar discectomy were 2.1% at 30 days and 3.0% at 90 days. Diabetes mellitus was the only independent risk factor for reoperation.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
Background:
- Biportal endoscopic lumbar discectomy is a minimally invasive technique for lumbar disc herniation.
- Reoperation rates are important indicators of surgical outcomes and patient safety.
Purpose of the Study:
- To determine the incidence of 30- and 90-day reoperations after biportal endoscopic lumbar discectomy.
- To identify risk factors associated with early reoperations following this procedure.
Main Methods:
- Retrospective cohort study including 1510 patients undergoing single-level lumbar discectomy.
- Analysis of patient demographics, herniation characteristics, and spinopelvic parameters.
- Multivariable logistic regression to identify risk factors for 30- and 90-day reoperations.
Main Results:
- The 30-day reoperation rate was 2.1% (31/1510) and the 90-day rate was 3.0% (46/1510).
- Recurrent disc herniation was the most common reason for reoperation.
- Diabetes mellitus (DM) and prolonged postoperative hospital stay were associated with reoperations, but DM was the only independent risk factor.
Conclusions:
- The incidence of early reoperations following biportal endoscopic lumbar discectomy is low.
- Diabetes mellitus is a significant independent risk factor for both 30- and 90-day reoperations.
- While prolonged hospital stay was noted, diabetes mellitus emerged as the primary modifiable risk factor.
