The purpose of this pictorial essay is to describe the main morpho- functional imaging features, physiological and pathological, of the recto-anal region and pelvic floor as depicted with conventional video defecography. Defecography has dramatically improved our knowledge of dysfunctions of evacuation. The most frequent indications and related disorders are presented from a database of more than 2500 examinations conducted in two radiology departments over a period of 15 years. Imaging features of the common recto-anal and pelvic floor disorders are described: rectal prolapse, rectocele, intussusception, descending pelvic floor syndrome, puborectalis muscle syndrome, enterocele, and sigmoidocele. Conventional video defecography still represents the gold standard examination for the identification and staging of morphological and functional disorders of the recto-anal region and pelvic floor in evacuation dysfunctions.
本影像学专题论文旨在描述直肠肛门区和盆底的主要形态-功能影像学特征，包括常规排粪造影检查所显示的生理学和病理学特征。排粪造影显著提高了我们对排空功能障碍的认识。本文从两个放射科 15 年来进行的超过 2500 例检查的数据库中，提出了最常见的适应证和相关疾病，并介绍了其影像特征：直肠脱垂、直肠前突、套叠、盆底下降综合征、耻骨直肠肌综合征、会阴疝和乙状结肠疝。常规视频排粪造影仍然是识别和分期排便功能障碍中直肠肛门区和盆底形态和功能障碍的金标准检查。
