What this trial studies

This research aims to establish baseline normative data for traditional anorectal function measurements using both air charged and solid state high-resolution anorectal manometry (HRAM) catheters. The study will utilize the IAPWG standardized testing protocol and London classification to compare the performance of these two types of catheters in healthy subjects. By gathering this data, the study seeks to enhance understanding of normal anorectal function parameters.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy male and female volunteers aged 18-65 who can provide informed consent.

Not a fit: Patients with a documented history of gastrointestinal disorders or those on medications affecting gastrointestinal motility may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable normative data that may improve the diagnosis and treatment of anorectal disorders.

How similar studies have performed: While this approach is focused on establishing normative data, similar studies have successfully utilized HRAM techniques to assess anorectal function.
