Influence of Body Position on the Defecation Model During Anorectal Manometry.

Anorectal 3D manometry (3D HRAM) is the most advanced version of manometric equipment that measures pressures along the anal canal in a very detailed manner. It provides complete data about pressure profile of anorectum and may indicate impaired defecation dynamics. Resent studies suggest that the position in which 3D HRAM is performed should be changed. So far, no scientific research has been performed in children that directly compares both positions. The reference values of registered pressures during 3D HRAM in people without complaints were not specified, which would allow for a more precise diagnosis of patients with an incorrect defecation model and precise selection of patients who could benefit from biofeedback therapy.
