Incidence and Risk Factors for 30- and 90-day Reoperations Following Biportal Endoscopic Lumbar Discectomy for...

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.
