近年来随着超声扫查仪分辨率日趋提高,有可能进行更准确的超声扫查。但普通腹部超声扫查不可能显示整个肠腔,故不能完全显示结肠疾病。逆行性将水灌入结肠作超声扫查,可改善超声显像及结肠检查的条件。业已证实,此法对结肠肿瘤和炎症性肠病,如克隆病、溃疡性结肠炎均可作出诊断,本文对研究结肠灌水超声和普通腹部超声对结肠肿瘤诊断和分期价值进行对比。 In recent years, with the increasing resolution of ultrasonic scanners, more accurate ultrasonic scans are possible. However, the normal abdominal ultrasound scan is not likely to show the entire intestine, so it cannot completely show colon disease. Retrograde water injection into the colon for ultrasound scanning can improve ultrasound imaging and colon examination conditions. It has been confirmed that this method can be used to diagnose colon cancer and inflammatory bowel disease, such as Crohn’s disease and ulcerative colitis. This article compares the diagnosis and staging value of colorectal ultrasound and common abdominal ultrasound for colon cancer.
