METHODS: We retrospectively collected the clinical data of patients with suspected MD.
RESULTS: A total of 58 children were included in this study. All 58 children presented overt gastrointestinal bleeding (bloody stool or melena). Capsule endoscopy identified protruding lesions in 2 cases, double-lumen changes in 30 cases (all considered as MD), vascular lesions in 7 cases, intestinal mucosal inflammatory lesions in 3 cases, ulcers or erosion in 3 cases, and no obvious abnormalities in SBCE in 12 cases. Both SBCE and technetium-99 scans were performed for 24 cases, 22 of which were diagnosed MD by their combined results, giving a diagnostic coincidence rate of 91.7%. Eight cases were highly suspected as MD but were negative for the technetium-99 scan and positive for SBCE.
CONCLUSIONS: SBCE has high accuracy in the diagnosis of MD in children, especially when performed in combination with a technetium-99 scan, which can greatly improve the diagnostic rate of MD in children.
方法:我们回顾性收集疑似MD患者的临床资料。
结果:本研究共纳入58名儿童。所有58名儿童均出现明显的胃肠道出血(血便或黑便)。胶囊内镜发现2例病灶突出,双腔改变30例(均为MD),7例血管病变,肠黏膜炎性病变3例,3例溃疡或糜烂,12例SBCE无明显异常。对24例患者进行SBCE和tech-99扫描,其中22人根据他们的综合结果被诊断为MD,诊断符合率为91.7%。8例高度怀疑为MD,但tech-99扫描阴性,SBCE阳性。
结论:SBCE对儿童MD的诊断具有较高的准确性,特别是当与tech-99扫描结合进行时,可以大大提高儿童MD的诊断率。
