目的:探讨超声检查对儿童消化性溃疡的诊断及其超声声像图特征。方法:回顾性分析2011年2月至2013年9月广州市妇女儿童中心收治的266例术前进行超声检查并经胃镜及病理证实为消化性溃疡患儿的超声表现。结果:超声诊断胃溃疡符合率为88.8%、十二指肠球部溃疡的符合率为85%。消化性溃疡的典型超声图像是大小深浅不同的消化道凹陷和凹陷基底部及周围消化道增厚呈低回声。而凹陷表面呈强回声。结论:超声诊断儿童消化性溃疡方便、无创、无放射性且检出率高。超声可以清楚分辨消化道壁的各层结构及溃疡改变。
Objective: To investigate the diagnostic value of ultrasonography in children with peptic ulcer and its sonographic features. Methods: A retrospective analysis was performed on 266 cases of children with peptic ulcer diagnosed by gastroscopy and pathology from 266 patients who underwent preoperative ultrasound examination in Guangzhou Women and Children’s Center from February 2011 to September 2013. Results: The coincidence rate of ultrasonic diagnosis of gastric ulcer was 88.8%, and the coincidence rate of duodenal ulcer was 85%. A typical ultrasound image of peptic ulcer is the size of the different depths of digestive tract depression and depression of the basal and peripheral gastrointestinal thickening was hypoechoic. The concave surface was a strong echo. Conclusion: Ultrasound diagnosis of children with peptic ulcer is convenient, noninvasive, non-radioactive and high detection rate. Ultrasound can clearly distinguish the digestive tract wall structure and ulcer changes.
