目的分析不明原因消化道出血(OGIB)的病因,比较CE(CE)与小肠结肠双期增强CT对OGIB的诊断价值及优势。方法临床诊断考虑为OGIB的患者101例,分别行CE及小肠结肠双期增强CT检查,计算CE及小肠结肠双期增强CT对不同病变的检出率,比较其差异。结果 101例行CE检查患者共发现病变77例,其中小肠病变69例,小肠外病变8例。小肠结肠双期增强CT发现病变25例,其中小肠病变15例,小肠外病变10例。两种方法的出血相关小肠病变检出率比较,差异有统计学意义(P<0.05)。结论 CE是对OGIB的有效检查方法 ,其病变检出率明显高于小肠结肠双期增强CT,临床上对于OGIB患者采用CT联合CE的检查方法可提高疾病的检出率并指导手术治疗。
OBJECTIVE: To analyze the etiological factors of obstructive gastrointestinal bleeding (OGIB) and to compare the diagnostic value and advantages of CE (CE) and colon and colon double phase enhanced CT in OGIB. Methods One hundred and one patients with clinical diagnosis of OGIB were enrolled in this study. CE and small intestine colon double-phase contrast-enhanced CT were performed respectively. The detection rates of CE and small bowel colon double-phase contrast enhanced CT were compared, and the differences were compared. Results A total of 77 lesions were found in 101 patients undergoing CE examination, including 69 cases of small bowel disease and 8 cases of small bowel disease. Intestinal double colon enhanced CT findings in 25 cases of lesions, including 15 cases of small bowel disease, small bowel disease in 10 cases. The two methods of bleeding-related small intestinal lesions detection rate, the difference was statistically significant (P <0.05). Conclusion CE is an effective OGIB examination method, the detection rate of lesions was significantly higher than that of small intestine colon double-phase enhanced CT, clinical OGIB patients with CT combined with CE examination can improve the detection rate of the disease and guide the surgical treatment.
