慢性炎症性肠病如克隆病和溃疡性结肠炎的形态学诊断至今仍建立在结肠放射学诊断和内窥镜检查基础上。由于超声分辨能力的不断提高,近年来超声在胃肠疾病诊断中的意义也日趋重要。常规腹部超声检查见病理性肠帽徽征提示结肠炎性或肿瘤病变。由此可见常规超声检查的局限性在于不能对肠壁结构层次和肠腔改变进行仔细判断。此外亦不能连续地对整个结肠进行检查。通过逆行性结肠内灌水,可显著改善结肠的超声显像,通过经腹壁检查技 The morphological diagnosis of chronic inflammatory bowel disease such as Crohn’s disease and ulcerative colitis is still based on the diagnosis of colon radiology and endoscopy. In recent years, the significance of ultrasound in the diagnosis of gastrointestinal diseases has become more and more important due to the continuous improvement of ultrasound resolution. Conventional abdominal ultrasound examination of pathological bowel cap emblem prompted colitis or tumor lesions. This shows that the limitations of conventional ultrasound is that the structure of the intestinal wall and intestinal changes can not be carefully judged. In addition, the entire colon can not be examined continuously. Through retrograde intracolonic irrigation, can significantly improve the colon ultrasound imaging, through the abdominal wall examination
