Summary

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.

Interventions

DEVICE

anorectal manometry

High-resolution anorectal manometry is done under standard clinical conditions with a 10 cm catheter inserted into the rectum loaded with pressure transducers at a distance of 6 mm in the sphincter area and an attached latex balloon at the catheter tip. It will measure the length of the anal sphincter, the static pressure and the clamping pressure during at least 3 over 40 seconds sustained maneuvers according to a standardized protocol. Mean and maximum pressure increase over the resting pressure during the first 30 seconds of the squeeze and the maximum possible squeeze time will be documented. Moreover, the initial anorectal perception threshold, the perception of urge to defecate and maximum tolerable volume balloon will be documented.

DEVICE

barostat

For the barostat study a balloon will be attached to the catheter. Instead of a barostat machine a 60ml syringe and a sphygmomanometer will be connected to the catheter and the catheter will be positioned in the rectum. The balloon is then dilated gradually to assess perception, urge and discomfort threshold in relation to rectal volume.
