Abstract
Background
Preoperative administration of oral antibiotic bowel preparation (OABP) alone has been shown to reduce infectious outcomes in patients undergoing elective colectomy. However, it remains unclear if these benefits extend to the emergency setting. This is a retrospective, propensity-score matched study comparing 30-day perioperative morbidity between those who received OABP alone versus no preparation prior to urgent colectomy.
Methods
Using the American College of Surgeons National Surgical Quality Improvement Program database, adults undergoing urgent colectomy from 2012 to 2019 were included. Those who were clinically obstructed or who received mechanical bowel preparation were excluded. Outcomes of interest included: surgical site infection (SSI), leak, ileus, and major morbidity.
Results
Of 24,559 patients meeting inclusion criteria, 878 (3.6%) received OABP prior to urgent colectomy. Prior to matching, those receiving no preparation were more likely to have higher ASA class, diabetes, hypertension, preoperative sepsis, open procedures, and a dirty wound classification. After matching, 1756 patients, remained with 878 in each arm. Preoperative characteristics were balanced on univariate analysis. Postoperatively, patients receiving OABP experienced decreased organ space SSI (11.2% vs. 15.5%, p = 0.009) and ileus (30.3% vs. 35.3%, p = 0.029), with no difference in leak rates (3.3% vs 3.3%, p = 1.000) or NSQIP major morbidity (47.4% vs. 49.9%, p = 0.316). On multivariate logistic regression, including propensity score, the reduction in organ space SSI associated with OABP persisted (OR 0.684, 95% CI 0.516–0.903).
Conclusion
OABP prior to select urgent colectomies was associated with fewer organ space SSIs and may be considered when feasible.
