The present study investigates the intraindividual day-to-day variability of anorectal manometry parameters. Manometric studies were performed in twelve healthy volunteers on three different days. A low compliance capillary perfusion system was used. The values measured on day 1 and day 2, as well as those on day 2 and day 3, showed no significant (p greater than 0.05) differences for any parameter in Wilcoxon's test. Mean percentage of differences as a measure for intraindividual day-to-day variation was relatively low for anal resting (mean: 13.5%) and maximal squeeze (17.5%) pressure. However, it was high for the threshold volumes for minimal perception (71.8%) and urgency to defecate (38.5%) during rectal balloon distention as well as for the minimal volume required to abolish recovery of the rectoanal inhibitory reflex (41.2%). We conclude that anal resting pressure and maximal squeeze pressure both are the most stable anorectal manometry parameters in man, at least over a period of a few days.

D008297	Male		Males
D008365	Manometry	Measurement of the pressure or tension of liquids or gases with a manometer.	Tonometry,Manometries
D008838	Microcomputers	Small computers using LSI (large-scale integration) microprocessor chips as the CPU (central processing unit) and semiconductor memories for compact, inexpensive storage of program instructions and data. They are smaller and less expensive than minicomputers and are usually built into a dedicated system where they are optimized for a particular application. "Microprocessor" may refer to just the CPU or the entire microcomputer.	Computers, Personal,Microprocessors,Computer, Personal,Microcomputer,Microprocessor,Personal Computer,Personal Computers
