Anorectal physiology

Abstract

The most import clinical manifestation of abnormal anorectal physiology is anal incontinence, and this, together with its causes, is comprehensively reviewed in this chapter. The physiology includes studies on anorectal and colonic functions, using manometric and electrophysiological studies. The latter includes motor and sensory nerve conduction and electromyography. Measurements of colonic transit rely on radioisotope studies, such as defecation scintigraphy, and dynamic studies, such as defecography. © 2008 Springer-Verlag London.
