The aim of this monocentric, prospective, non randomised study with 25 healthy volunteers is
to assess anorectal function ( i.e rectal compliance and sensory thresholds) in health with a
short protocol barostat versus conventional procedures (i.e. standard barostat protocol and
high resolution anorectal manometry). Anorectal dysfunction is a key mechanism in the
development of fecal incontinence and symptoms of obstructive defecation.
In this study volunteers will be examined - after explanation, physical examination and
verification of in- and exclusion criteria - by anorectal barostat with short and standard
protocol as well as by proctoscopy and endoanal ultrasound.
