Summary

Defecatory disorders like chronic constipation and faecal incontinence affect 25% of the population with rising incidence. Defecatory disorders pose a major health care burden and are poorly recognized and treated. The need for better diagnostics and therapeutics is substantial.

Current assessment of patients with constipation and faecal incontinence include endoscopic assessment to rule out intraluminal organic cause for patients' symptoms, endoanal ultrasound scan / MRI to assess patients' pelvic floor anatomy and anorectal manometry and balloon expulsion test to assess anorectal function. All tests are susceptible to measurement artifacts.

The standard technologies for anorectal assessment are anorectal manometry, balloon expulsion test and defecography. Endoluminal Functional Lumen Imaging Probe (EndoFLIP©) is a novel technology, originally used to measure the dimensions and function of a hollow organ. Anorectal manometry, balloon expulsion test, defecography, and the EndoFLIP probe will be used in the proposed studies. In addition, the proposed study intends to use a simulated feces named Fecobionics which is a device that integrates several technologies into one which will save time and reduce test variability.

In the proposed studies investigators will assess defecatory function in subgroups of Hong Kong patients suffering from chronic constipation and faecal incontinence and determine biomarkers to increase the diagnostic value of anorectal testing. Investigators will study up to 130 patients with anorectal disorders and 101 healthy control subjects. Investigators anticipate to improve diagnostics of anorectal disorders considerably and to learn about physiological mechanisms that affect defecatory efficacy.
