Purposes.Mesenteric venous thrombosis (MVT) is a serious condition. Thecurrent study aimed to identify risk factors of intestinal\nnecrosis (IN) in patients with MVT to predict the onset of patients. Methods. Data pertaining to patients diagnosed with MVT\nbetween 2014 and May 2018 were reviewed. Patientsâ?? characteristics and risk factors of IN were assessed. Results. Seventy-eight\npatients were included in our study, of whom all cases were diagnosed as superior mesenteric venous thrombosis. There were\nfifty-eight cases (74%) with intestinal necrosis and twenty cases (26%) without intestinal necrosis. Multivariate analysis of factors\nassociated with IN was organ failure (odds ratio (OR): 4.1; 95% confidence interval (95%CI): 1.26-8.59; P=0.028), elevated serum\nlactate (OR:3.6; 95%CI: 1.51-5.47; P=0.024),bowel loopdilation on computerized tomography(CT) scan(OR: 2.8; 95%CI: 1.32-7.23;\nP=0.031), and the time between onset of symptoms and operation (OR: 4.8; 95% CI: 1.36-9.89; P=0.012). Area under the receiver\noperating characteristics curve for the diagnosis of IN with MVT was 0.901 (95%CI: 0.809-0.993; P=0.000) depending on the\ndifferent number of predictive factors. Conclusion. Predictive risk factors for IN with MVT were organ failure, elevated serum\nlactate level, bowel loop dilation on CT, and the time between onset of symptoms and operation. However, this result is from a\nretrospective study and further long-term, large-sample prospective studies are required to confirm this finding.
