肛肠动力学是近年来胃肠动力学发展中的一个重要分支。它以静力学和动力学及肌电为主的方法来研究结肠、直肠、肛管(包括盆底)的各种运动方式,从而对排便生理及有关肛肠疾病的病理生理学进行研究。肛肠动力性疾病主要表现为肛肠动力异常所致的便秘、腹泻、肛门失禁,并常伴随腹 Anorectal dynamics is an important branch in the development of gastrointestinal dynamics in recent years. It uses static and kinetic methods and myoelectric primary method to study the colon, rectum, anal canal (including the pelvic floor) of the various exercise patterns, and thus on the bowel physiology and the pathophysiology of anorectal disease research. Anorectal motility disorders mainly due to anorectal abnormalities caused by constipation, diarrhea, anal incontinence, and often accompanied by abdominal
