摘　　要：目的：探索肠道超声显影剂在结直肠病变中的应用价值。方法：空腹排便后服肠道超声显影剂７０～１００ｍｌ，饮水５００～７００ｍｌ，有便意后检查。结果：超声对中晚期结直肠癌检出率为９８％，定位准确率９２．１％，定性符合率７８．２％。早期肿瘤检出率与肠道的清洁程度及检查者的经验有关。该方法对良恶性肿瘤的鉴别有一定的临床价值。非占位性病变的检出率低于占位性病变，但所漏检的多为浅表小病变。结论：口服肠道超声显影剂的开发应用，拓宽了超声检查领域，为临床提供了一种新型、无创、快捷的检查方法。该药无毒副作用，符合国家药典规定，易于推广应用。Objective: Study of diagnosing colorectal disease using oral ultrasonic bowel contrast solution. Methods: After defecation, the patient took 70-100ml contrast agent and 500-700 ml water, until the agent filled the colorectum, then examination started. Results: The detectable rate was 98%, the locative accurate rate was 92.1 % and the qualitative coincidence rate was 78 .2% in middle-late stage of colorectal cancer with ultrasound. The detectable rate of early stage tumor was concered with the clean degree of colorectal tract and the experience of examiner. It can identify the benign from malignancy in some degree. The detectable rate of ultrasound for colorectal non-space-occupied lesion was lower than that of colorectal space- occupied lesion. Most of the miss-dignosed were small or slight. Conclusion: Oral ultrasonic contrast agent diagnosing colorectal disease is feasible. It's a convenient and quick screening method.
