Chapter 3 discusses the anorectum, which is responsible for the control of defaecation and maintenance of continence. Proper function requires integration of the pelvic floor, rectal compliance, and pelvic sensorimotor function. Disorders of the anorectum often have complex pathophysiology and manifest in a number of ways, in particular rectal outlet obstruction, faecal incontinence (FI) and pain. These conditions are gaining increasing attention, in part due to their increasing prevalence in the aging Western population.
