摘要
目的:分析上消化道出血胃B超图象特征,探讨B超对上消化道出血及其病因诊断的意义。方法:选择上消化道出血活动期的位院患者49例,分别于空腹及饮水后依次探查贲门、胃体、胃窦、十二指肠及其邻近器官,记录图像,并结合内镜病理及X线结果进行分析。结果:49例中,B超检出相关疾病41例,命中37例;检出率及准确率分别为83.7％和75.5％,X线报告32例,命中29例,检出率及准确率分别为65.3％和59.2％,统计分析结果显示该两种检查方法有显著差异(P<0.05)。结论:B型超声可作为上消化道出血病因诊断较可靠的方法。
Objective To analyse the ultrasonic image features of upper gastrointestinal tract bleeding (UGIB)and explore the of ultrasonic diagnosis on the causes of UGIB. Methods: The car-dia - antrum, corpus, duodenum nad the adjacent organs of stomach were probed in turn by ultrasonic analysis in 49 patients with UGIB before and after water drinking who were defined by en-doscope and histology biopsy, compared with X - ray examination. Results:The ultrasonic screened out 17 cases of ulcerative disease , 10 cases of gastric cancer , 7 cases of eaophageal varices, 3 cases of acute gastric mucosal lesion, 1 case of duodenitis, 1 case of duodenal cancer, 1 case of Mallory -Weiss syndrome and 1 case of gastric stone as well. The revealing rate and accurate rate were 83. 70% and 75. 50% respectively, were significant statistic ally different from X - ray examination (65.30% and 59.20% respectively). Conclusion: Our findings suggested that the ultrasonimetric analysis is secure and accurate for detecting UGIB and its causes.
