摘　　要：目的分析对比增强CT在消化道出血疾病中的临床应用价值。方法选定嵩县人民医院2022年4月至2024年4月就诊的160例消化道出血患者,均给予增强CT检查,统计出血部位、影像学特征。比较增强CT动脉期、静脉期、延迟期出血点CT值。结果160例患者经增强CT检查确定出血部位,食管72例,占45.0%;胃46例,占28.7%;肠道42例,占26.3%。8例表现为肠道血管畸形,占5.0%,具体表现为局部血管从增粗、增多、粗细不一、紊乱,其中2例胃血管畸形、2例十二指肠血管畸形、2例小肠血管畸形、2例直肠血管畸形。72例食管静脉曲张,被确诊为肝硬化,占45.0%。54例表现为肠道肿瘤,占33.8%,具体表现为肠壁软组织密度肿块或不规则增厚,伴有周围淋巴结肿大、肠腔狭窄,其中36例胃肠道间质肿瘤;4例结肠癌;4例十二指肠癌;8例胃癌;2例小肠淋巴瘤。26例表现为局部或节段肠黏膜异常强化,占16.5%,其中4例空肠局部黏膜异常强化;4例回肠局部黏膜异常强化;18例回盲部黏膜异常强化。静脉期、延迟期出血点CT值均较动脉期出血点更高(P<0.05),静脉期出血点CT值与延迟期比较,差异无统计学意义(P>0.05)。结论增强CT可明确消化道出血的部位以及原因,辅助临床准确评估患者病情,另外静脉期、延迟期是显示出血点的最佳时相,临床可根据患者实际情况合理选择扫描时相。Objective The clinical application value of contrast-enhanced CT analysis in gastrointestinal bleeding diseases.Methods A total of 160 patients with gastrointestinal bleeding who were selected to visit Songxian People's Hospital from April 2022 to April 2024 were all given enhanced CT scans,and the bleeding site and imaging characteristics were recorded.Compare the CT values of bleeding points in arterial,venous,and delayed phases of contrast-enhanced CT.Results A total of 160 patients were confirmed to have bleeding sites through enhanced CT examination,with 72 cases in the esophagus,accounting for 45.0%;46 cases of stomach,accounting for 28.7%;42 cases in the intestine,accounting for 26.3%.Eight cases showed intestinal vascular malformation,accounting for 5.0%,specifically manifested as local blood vessels thickening,increasing,uneven thickness,and disorder,including 2 cases of gastric vascular malformation,2 cases of duodenal vascular malformation,2 cases of small intestinal vascular malformation,and 2 cases of rectal vascular malformation.Seven-two cases of esophageal varices were diagnosed as cirrhosis,accounting for 45.0%.Fifty-four cases presented as intestinal tumors,accounting for 33.8%.The specific manifestations were soft tissue density masses or irregular thickening of the intestinal wall,accompanied by peripheral lymph node enlargement and intestinal lumen stenosis.Among them,36 cases were gastrointestinal stromal tumors;4 cases of colon cancer;4 cases of duodenal cancer;8 cases of gastric cancer;2 cases of small intestinal lymphoma.Twenty-six cases showed local or segmental intestinal mucosal abnormal enhancement,accounting for 16.5%,of which 4 cases had local mucosal abnormal enhancement in the jejunum;4 cases of abnormal enhancement of local mucosa in the ileum;18 cases of abnormal enhancement of the mucosa in the ileocecal region.The CT values of bleeding points in the venous and delayed phases were higher than those in the arterial phase(P<0.05).There was no significant difference in CT values b
