Objectives: To identify treatments likely to prevent progression towards irreversible transmural intestinal necrosis (ITIN) in acute mesenteric ischemia (AMI).
Methods: Prospective observational cohort study from a French intestinal stroke center. Multivariate analysis using a time-dependent Cox regression model.
Results: Between 2009 and 2015, 67 patients with AMI were included. ITIN occurred in 34% of patients and mortality was 13%. Oral antibiotics was independently associated with a decreased risk of ITIN (HR: 0.16 (95% CI = 0.03-0.62); p = 0.01).
Conclusions: By decreasing luminal bacterial load and translocation, oral antibiotics in addition to early revascularization might reduce progression of AMI to ITIN.
