摘　　要：BACKGROUND Ileus is a pathological condition of the abdomen that presents as a medical emergency.It is characterized by potential complications such as perforation and ischemia,which can lead to significant morbidity and mortality if not promptly addressed.The successful management of ileus relies heavily on the timely and precise identification of the condition.While conventional radiography(CR)is commonly used as the primary diagnostic tool,its accuracy in identifying obstructions ranges from 46%to 80%.Furthermore,the diagnostic accuracy of identifying the location and etiology of intestinal obstruction by CR is limited,therefore making computed tomography(CT)the ideal imaging modality in this regard.AIM To determine the presence of acute bowel obstruction(BO)on abdominal CT scenogram images and the accuracy of determining its possible location,taking into account the experience of the observers.METHODS A retrospective screening was conducted on an ensemble of 46 individuals who presented to the emergency department between January 2021 and January 2022 with severe abdominal pain and were subsequently monitored for suspected ileus.The abdominal CT scans of these patients were assessed by three radiologists with varying levels of experience(1,3,and 10 years)at different intervals(1 mo apart).The evaluation focused on determining the presence or absence of BO,as well as identifying the potential location of the obstruction(small bowel or large bowel).The study employed Kappa statistics to assess inter observer variances,while the McNamer test was used to evaluate obstruction and segmentation discrepancies between observations.A significance level of P<0.05 was determined to indicate statistical significance.RESULTS Out of the total sample size of 46 patients,15 individuals(32.6%)were identified as female,while the remaining 31 individuals(67.4%)were identified as male.The ultimate diagnosis of 42 instances(91.3%)indicated ileus resulting from mechanical obstruction(MO).Among these patients,14(33%)experienced obst
