近十年来,对直肠肛管的病理生理学研究,特别是对功能性疾病如失禁、脱垂、便秘等的研究越来越多。本文是关于直肠排粪造影的专题讨论,由Finiay主持,10位外科及放射科医生参加了讨论。方法与技术直肠排粪造影是对直肠肛管作动力学研究的重要手段之一。可以测量静息或屏力状态下的肛管直肠角,观察肛管直肠与耻尾线关系的变化。与测压仪,肌电图结合使用可测定直肠压力、括约肌及耻骨直肠 In the past ten years, the research on the pathophysiology of the rectum anal canal, especially for functional diseases such as incontinence, prolapse, constipation and so on, has been increasing. This article is a symposium on rectal defecography, moderated by Finiay, and included 10 surgeons and radiologists. Methods and techniques Rectal defecography is one of the most important means to study the dynamics of the rectum anal canal. Can be measured resting or screen state of the anal canal angle, observe the anal canal and shame line changes. Combined with manometry and electromyography, rectal pressure, sphincter and puborectalis can be determined
