摘要：

<正>慢性便秘根据与解剖相关的发生机制可分为慢传输性便秘、出口梗阻性便秘和混合型便秘。慢传输性便秘是由于各种原因引起的结肠运动功能迟缓、传输粪便功能下降而导致的便秘,临床上比较常见;主要表现为没有便意、大便干结、需依赖泻剂进行排便。根据其发病机制可分为继发性便秘和特发性便秘两种类型。出口梗阻性便秘则是由于直肠、肛门或盆底解剖或功能异常导致的排便困难。患者通常有比较强的便意,但排出困难,每天需要很长时间排便,或需使用开塞露、灌肠,用手压迫会阴或阴道排便,并且常有排便不尽感。发病原因包括盆底、直肠松弛性病变(如直肠内套叠、直肠内脱垂、直肠前突、盆底和会阴下降等)及肛管痉挛性病变(如耻骨直肠肌肥厚、耻骨直肠肌或盆底肌痉挛综合征等)。混合型便秘包括慢传输性便秘和出口梗阻性便秘两方面的特点。
