摘　　要：1975年Thomson提出的"肛垫学说"使人们对痔有了全新的认识。在解剖层次上,肛垫由肛垫上皮、黏膜下血管、肛垫黏膜下结缔组织构成,宛如心脏瓣膜,协助括约肌维持肛管的正常闭合。本文对肛垫解剖结构的病理生理、脱垂性痔形成机制的研究进展作一综述。In 1975, Thomson proposed the theory of anal cushion for a brand new understanding of hemorrhoids. At the anatomical level, anal cushion is constituted by anal cushion epithelium, submucosal blood vessels and anal cushion submucosal connective tissue, which assists sphincter to close the anal tube normally just like the heart valve. This paper reviews the physiopathology of anal cushion and the formation mechanism of prolapse hemorrhoids.
