Abstract

Background: Delayed operative intervention in the setting of adhesive bowel obstruction has been recently shown to increase the rate of surgical site infection (SSI), raising the concern for bacterial translocation. The effect of obstruction on SSI rate in patients with ventral hernia is unknown. The aim of this study was to assess the association between bowel obstruction and SSI in patients undergoing ventral hernia repair (VHR). Materials and methods: This study is a retrospective database review. Patients undergoing isolated VHR from 2005–2011 were identified from the American College of Surgeons' National Surgical Quality Improvement Program database. Demographics, comorbidities, and 30-d outcomes were analyzed. Multivariate logistic regression was used for variables with a P value of <0.1. Results: A total of 68,811 patients underwent isolated VHR; 53.1% were male with mean age of 53 ± 15 y and body mass index of 32 ± 8. Hernia-related obstruction was found in 17,058 (24.8%). In patients with obstruction, SSI was more frequent (3.2% versus 2.6%, P < 0.001). Obesity, advanced age, vascular, pulmonary, hepatic, renal disease, and diabetes were more prevalent. After controlling for confounding baseline variables, bowel obstruction was not independently associated with SSI (odds ratio, 0.983, 95% confidence interval, 0.872–1.107). Subgroup analysis of clean classified cases also demonstrated the lack of independent association between obstruction and SSI. Conclusions: Obstruction in patients undergoing VHR is not independently associated with SSI. Our results suggest that mesh implantation remains a viable option in this setting. Other confounding comorbid conditions should be assessed at the time of surgical intervention to identify patients appropriate for mesh repair.
