Unintended Consequences After Postoperative Ileus in Spinal Fusion Patients

Area of Science:

• Spinal Surgery Outcomes
• Gastrointestinal Complications
• Patient Safety

Background:

• Postoperative ileus is a common complication following spinal surgery.
• Previous research has primarily focused on the incidence of ileus, with limited investigation into its clinical consequences.
• This study addresses the need to understand the impact of ileus on patient outcomes.

Purpose of the Study:

• To investigate the clinical sequelae of postoperative ileus after spinal fusion surgery.
• To determine the effect of ileus on length of hospital stay.
• To assess the association between ileus and adverse events including deep vein thrombosis (DVT), myocardial infarction (MI), aspiration pneumonia, sepsis, and mortality.

Main Methods:

• Utilized the Healthcare Cost and Utilization Project National Inpatient Sample database.
• Included adult patients undergoing spinal fusion procedures.
• Compared outcomes between patients with and without postoperative ileus using statistical tests (Rao-Scott chi-squared, t-test) and multivariate regression analysis.

Main Results:

• A total of 250,221 patients were analyzed.
• Patients with postoperative ileus had a significantly longer mean hospital stay (9.40 days vs. 3.75 days).
• Ileus was associated with substantially higher rates of DVT (20.8% vs. 4.1%), MI (7.1% vs. 2.5%), aspiration pneumonia (34.3% vs. 6.6%), sepsis (35.7% vs. 5.7%), and death (11.4% vs. 2.6%).

Conclusions:

• Postoperative ileus following spinal surgery is linked to significantly worse patient outcomes.
• Patients experiencing ileus face increased risks for major adverse events and mortality.
• The findings underscore the importance of managing and preventing ileus to improve patient safety and reduce healthcare burden.
