RESUMO
Objective@#This study aimed to identify predictive factors for suspected intestinal ischemia (II) when compared with those of acute gastroenteritis (AGE) in the emergency department (ED). @*Methods@#This single-center retrospective case-control study included 71 patients with II and 355 with AGE who visited the ED from 2014 to 2021. We attempted to compare the initial clinical presentation and laboratory examination findings of the II and AGE patients. The data in this study were analyzed using the chi-square test, Student t-test, and logistic regression analysis. @*Results@#The analyses showed that patients with II accounted for only about 0.018% of patients visiting the ED. The logistic regression analysis results revealed that age >51 years (odds ratio [OR], 9.75; 95% confidence interval [CI], 3.84-24.75), onset-to-visit time 51 years; onset-to-visit time is <48 hours; symptoms of lower abdominal pain and hematochezia are present, there is PMHx of A-fib, hyperglycemia, and hypoalbuminemia; and diarrhea, febrile feeling/chill, and fever are absent.
