探讨MSCT依据肠管分布联合肠系膜血管走行对消化道出血精准定位的价值

The Value of Multi-slice Computed Tomography Based on Intestinal Distribution Combined with Mesenteric Vascular Travel for Accurate Localization of Gastrointestinal Bleeding

  • 摘要: 目的:评价MSCT依据肠管分布联合肠系膜血管走行对消化道出血(gastrointestinal bleeding,GIB)精准定位的能力。方法:搜集2021年1月至2023年9月于我院临床诊断GIB并行腹部CT增强扫描且经手术或内窥镜确诊GIB病例的临床及影像资料,由两名观察者(副主任医师及以上)采用双盲法回顾性分析所有病例MSCT薄层轴位图像,记录有无GIB;出血病例采用两种观察方法确定出血部位,A组:依据肠管分布判断出血部位,B组:依据肠管分布联合肠系膜血管走行判断出血部位。比较两种方法的对GIB精准定位的能力。结果:经手术或内窥镜确诊GIB的病例130例,MSCT检出GIB 109例,准确率83.85%;A组(依据肠管分布)定位出血部位71例,定位准确率为65.14%;B组(依据肠管分布联合肠系膜血管走行)定位出血部位85例,定位准确率为77.98%,P<0.05差异有统计学意义。结论:MSCT依据肠管分布联合肠系膜血管走行定位GIB部位的准确性优于单纯依据肠管分布。

     

    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 (P<0.05). 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.
