摘要
Abstract
Objective:This study aimed to evaluate the accuracy of multi-slice computed tomography(MSCT)to locate gastrointestinal bleeding(GIB)based on intestinal distribution combined with mesenteric vascular travel.Methods:The clinical and imaging data of GIB cases diagnosed in our hospital between January 2021 and September 2023 were collected and confirmed by surgery or endoscopy by abdominal CT-enhanced scanning,Two associate chief physicians retrospectively analyzed the thin-slice axial images of MSCT in all cases using the double-blind method,and recorded the presence or absence of GIB.Two observation methods were used to determine the bleeding site;the bleeding site was judged according to the intestinal distribution(group A),and intestinal distribution combined with mesenteric vascular travel(group B).The accuracy of both methods to locate the GIB was compared.Results:There were 130 cases of GIB diagnosed by surgery or endoscopy,and 109 cases were detected by MSCT,with an accuracy rate of 83.85%.There were 71 cases in group A and 85 cases in group B,and the accuracy to locate the bleeding site was 77.98%,with a statistically significant difference.Conclusion:The accuracy of MSCT in locating GIB sites based on intestinal distribution combined with mesenteric vascular travel is better than that based on intestinal distribution alone.关键词
