Values From Three-dimensional High-resolution Anorectal Manometry Analysis of Children Without Lower Gastrointestinal Symptoms

Methods of anorectal manometry vary widely in clinical practice: Results from an international survey

“…In addition, although (limited) normal values for different catheter types and populations exist, a robust description of pathological measurements seen using HR‐ARM is yet to be established. This is likely to explain our finding that, compared to those using conventional ARM, clinicians using modern HR‐ARM equipment put more emphasis on qualitative descriptions of global anorectal function than quantitative pressure measurements.…”

Anorectal manometry in children with defecation disorders BSPGHAN Motility Working Group consensus statement

“…One of the principle challenges to adopting HRAM or conventional ARM in children is to establish new normative data sets of an adequate size for recognized measures of anal sphincter function, and to promote standardization of the technique so that results are transferrable between institutions, a problem that has bedeviled traditional practice. At present, there are numerous published data of findings in healthy adults, with even fewer within pediatrics . In the absence of true pediatric normal values, this working group suggest to use adult values for children over the age of 12 years and to adopt the values published by Banasiuk et al as it represents the largest pediatric series of children without lower GI symptoms (Table ).…”

We acknowledge the different equipment used by this group, as 3D HRAM may not exactly match the results from standard HRAM or conventional ARM, but the study is the largest to date in children.…”

An ANMS‐NASPGHAN consensus document on anorectal and colonic manometry in children

“…The effect of rectal distension on anal relaxation and rectal sensitivity is affected by the size and the type of the balloon and the location of the balloon and normal values vary from laboratory to laboratory. Normative data has been recently published for the 3D probe, demonstrating a resting pressure of 83 ± 23 mm Hg, with a mean volume to elicit the RAIR of 15.7 ± 10.9 mL . The interpretation of the ARM is done mostly by evaluating the basal anal resting pressure and the normal presence of the RAIR (Fig.…”
