应用口服肠道超声显影液诊断结直肠非占位性病变

Using Ultrasounic Oral Bowel Contrast Solution to Diagnosing Colorectal Non Space Occupied Lesion

目的：通过与肠镜对照的双盲法、正向法、逆向法，探索超声在结直肠非占位性病变中的应用价值。材料和方法：空腹排便后，服自制口服肠道超声显影液７０～８０ｍｌ，饮水５００～７００ｍｌ，待有便意后检查。结果：本组８２例，溃疡性结肠炎３６例，检出率（２５／３６）６９．４％。结肠炎３７例，检出率（１８／３７）４８．６％。肠结核３例，全部检出。肠梗阻６例，亦全部检出，病因诊断符合（５／６）８３．３％。结论：受病理改变的影响，超声对结直肠非占位性病变的检出率较占位性病变为低，超声未检出者虽不能排除结肠炎，但所漏检的，多为小的或较轻的病变，超声能检出者，多数肠镜有相应改变，因此超声不失为一种方便、快捷的检查方法。

Purpose:To evaluate the application of ultrasound in colorected non space occupied lesion with contrasting colonoscopy by single or double blind methods.Material and Methods:First fasting,discharging and then taking 50 70ml oral ultrasonic bowel contrast solution and 500 700ml water.The examination should begin as desire to defecate.Resulte:There were 82 cases in the group.Ulcerative colitis was found in 36 cases with the detectable rate of (25/36) 69.4%.Colitis was found in 37 cases with the detectable rate of (18/37) 48.6%.Tuberculosis of colon was found in 3 cases with the detectable rate of 100%.Obstraction of colon was found in 6 cases with the detectable rate of (6/6) 100%.The etiologic diagnostic rate (5/6) 83.3%.Conclusion:Affected by pathologic change the detectable rate of ultrasound for colorectal non space occupied lesion was lower than that of colorectal space occupiected lesion.The diagnosis could not be negative although colitis was not de by ultrasound.Most of the missed diagnosed were small or slight.So ultrasound was a convenient and quick screening method.
