    ObjectiveTo investigate the incidence, risk factors, and outcomes of colon involvement in patients with necrotizing pancreatitis.Summary/Background DataNecrotizing pancreatitis is characterized by a profound inflammatory response with local and systemic implications. Mesocolic involvement can compromise colonic blood supply leading to ischemic complications; however, few data exist regarding this problem. We hypothesized that the development of colon involvement in necrotizing pancreatitis (NP) negatively affects morbidity and mortality.MethodsSix hundred forty-seven NP patients treated between 2005 and 2017 were retrospectively reviewed to identify patients with colon complications, including ischemia, perforation, fistula, stricture/obstruction, and fulminant Clostridium difficile colitis. Clinical characteristics were analyzed to identify risk factors and effect of colon involvement on morbidity and mortality.ResultsColon involvement was seen in 11% (69/647) of NP patients. Ischemia was the most common pathology (n = 29) followed by perforation (n = 18), fistula (n = 12), inflammatory stricture (n = 7), and fulminant C difficile colitis (n = 3). Statistically significant risk factors for developing colon pathology include tobacco use (odds ratio (OR), 2.0; 95% confidence interval (CI), 1.2-3.4, P = 0.009), coronary artery disease (OR, 1.9; 95% CI, 1.1-3.7; P = 0.04), and respiratory failure (OR, 4.7; 95% CI, 1.1-26.3; P = 0.049). When compared with patients without colon involvement, NP patients with colon involvement had significantly increased overall morbidity (86% vs 96%, P = 0.03) and mortality (8% vs 19%, P = 0.002).ConclusionColon involvement in necrotizing pancreatitis is common; clinical deterioration should prompt its evaluation. Risk factors include tobacco use, coronary artery disease, and respiratory failure. Colon involvement in necrotizing pancreatitis is associated with substantial morbidity and mortality.Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
