Anorectal manometry is usually performed with an open-tipped tube or a closed balloon system. To overcome the well known measurement problems and errors associated with fluid-filled catheter systems and balloons, a pressure tranducer was used to perform anorectal manometry. This method, performed on more than 200 individuals with different anorectal disorders, is described. This was found to be a simple, reliable and reproducible method for anorectal manometry.
