    【摘要】目的 探讨直肠腔内超声(ERUS)显示Denonvilliers筋膜解剖结构特点的可行性。 方法 回顾性分析15例男性直肠癌患者术前ERUS图像，观察辨别Denonvilliers筋膜解剖结构特点，并与术中腹腔镜所见进行对照。其中1例实施术中ERUS与腹腔镜下所见进行对照以验证术前ERUS识别的结构是否为Denonvilliers筋膜。结果 在ERUS图像上，走行于直肠固有筋膜与前列腺、精囊腺之间的线状高回声部位为Denonvilliers筋膜，顯示率达100%。15例术前ERUS图像与术中腹腔镜所见均相符。Denonvilliers筋膜与前列腺后方包膜贴合紧密，在精囊后方有疏松较宽间隙。在精囊腺后方及侧方存在结构个体差异，依据线状高回声数量的不同可分为单层结构(3例)及多层结构(12例)。结论 ERUS可以准确显示Denonvilliers筋膜解剖结构特点。
