目的分析肠结核的常规超声及超声造影的表现特点。方法回顾性分析17例经临床证实为肠结核的患者,观察病变肠管壁的厚度及其他肠外表现,超声造影剂在肠管壁的增强模式及程度。结果 17例肠结核肠管壁厚度范围在0.56~2.20cm,平均(1.39±0.5)cm。超声造影中增强模式表现为2种形式:15例表现为肠管壁弥漫性全层快速增强,2例表现为肠管壁浆膜层首先增强,然后向黏膜层逐渐增强。增强强度表现为13例肠管壁弥漫性均匀性增强,4例肠管壁不均匀增强。结论超声造影对肠结核的肠管壁微循环血流灌注情况可提供有价值的信息,对肠结核的诊断有一定的应用价值。
Objective To analyze the performance characteristics of conventional ultrasound and contrast-enhanced ultrasound in intestinal tuberculosis. Methods A retrospective analysis of 17 cases of clinically confirmed intestinal tuberculosis patients observed lesions of the intestinal wall thickness and other parenteral manifestations of ultrasound contrast agent in the intestinal wall enhancement mode and extent. Results The intestinal wall of 17 cases of intestinal tuberculosis ranged from 0.56 to 2.20 cm in average (1.39 ± 0.5) cm. Contrast enhanced ultrasound imaging showed two forms: 15 cases of diffuse bowel wall showed full enhancement of the whole layer, 2 cases of intestinal wall serosal first enhanced, and then gradually increased to the mucosal layer. Enhanced intensity showed diffuse homogeneity of 13 cases of intestinal wall enhancement, 4 cases of intestinal wall unevenly enhanced. Conclusions Ultrasound can provide valuable information for intestinal microcirculation perfusion of intestinal tuberculosis, and has certain value in the diagnosis of intestinal tuberculosis.
