Anorectal Manometry
9.1
Introduction
The anorectal manometry investigation is used to objectively assess the
apparatus and defecation provided by the anorectal sphincter. With anorectal
manometry, you can measure resting and squeeze pressure, as well as the
length of the functional anal canal. More detailed assessment of radial and
longitudinal pressure profiles can be obtained from a vector volume plot. With
use of an intra-rectal balloon, it is also possible to assess the recto-anal
inhibitory reflex (RAIR), rectal sensitivity, capacity, and compliance.
For the anorectal manometry investigation, the following tests are available:
4
•
Resting pressure
•
Squeeze
•
Endurance squeeze
•
Cough
•
Push
•
Rectal anal inhibitory reflex (RAIR)
•
Sensation test
•
Anal rest profile
•
Anal squeeze profile
•
Rectal compliance
•
Balloon expulsion
In this chapter, you will find information about the investigation protocol
settings, selection and preparation of catheters and transducers, the anorectal
manometry tests and (conventional) analysis.
HRAM
For the High-Resolution Anorectal Manometry (HRAM) software option, a
separate manual is available which describes the preparation of a HRAM
investigation and the HRAM software program (measurement program and
analysis program, document code LBL-001028
HRAM User’s Manual).
