In a study of 60 patients suspicious of free fluid we found a very high sensitivity of 95% and specificity of 100% with endorectal sonography. In 6 patients free fluid could be shown preoperatively by endorectal ultrasound, whereas transabdominal sonography proved to be negative. We conclude that endorectal sonography should be performed in all cases with a clinical suspicion of free fluid when transabdominal sonography is negative. Rectal endosonography is an easy and less stressful examination which clarifies conditions in the pelvis which are not clearly discernible from the transabdominal sonography.
在一项针对60例疑似存在游离液体患者的研究中，我们发现经直肠超声检查具有95%的高灵敏度和100%的特异性。6例患者术前经直肠超声可显示游离液体，而经腹超声检查结果为阴性。我们得出结论，当经腹超声检查结果为阴性且临床怀疑存在游离液体时，均应进行经直肠超声检查。直肠内超声检查是一种简便且压力较小的检查方法，它能明确经腹超声难以清晰分辨的盆腔情况。
