Trial to Evaluate Fecobionics in Fecal Incontinence (FI) (NORMAL and ABNORMAL-FI)
What this study is about
The objective is to determine the length-tension properties of the anal sphincters using Fecobionics in normal subjects and FI patients during anal distension and during simulated evacuation.
View original scientific description
The objective is to determine the length-tension properties of the anal sphincters using Fecobionics in normal subjects and FI patients during anal distension and during simulated evacuation. Fecobionics has the consistency and shape of normal stool and can record pressures, cross-sectional area, orientation and viscoelastic properties of the anorectum and can map the geometric profiles during evacuation, and thereby provides multi-dimensional measurements of pressures, deformability, and topographic changes. Fecobionics combines several existing tests to provide novel insight into anorectal function. The purpose for the development was to overcome the technological controversies and disagreement between various tests and unphysiological test conditions. The aim was to imitate defecation as much as possible to the natural process. Fecobionics was developed to simulate stool and to provide the driving pressure and resulting deformations of stool along with a measure of an objective anorectal angle during defecation in a single examination. Fecobionics makes it possible to describe objectively, without disturbing the defecation process, the opening characteristics and pressure signatures during initial entry into the relaxing anal canal. The overall goal is to provide mechanistic understanding of defecation in health and defecatory disorders. It exceeds previous attempts to make artificial stool for evaluation of defecation (BET and FECOM) and integrates other technologies as well. It was designed to have a consistency and deformability of Type 4 (range type 3-5) on the Bristol stool form scale. The range from types 3-5 is found in 70% of normal subjects. A major novelty is that Fecobionics measures pressures in axial direction; i.e., in the flow direction.
Interventions
DEVICE
Fecobionics
Fecobionics is a novel device to be inserted through the anal canal into rectum for studying defecation. Anorectal manometry, balloon expulsion test, and anal ultrasonography will be used as reference.
Primary outcome measures
Length-tension properties of the anal sphincter will be reported
Time frame: 1.5 year
Front-rear pressure difference (in cmH2O) will be measured
Time frame: 1.5 year
Fecobionics contain pressure sensors in front end and rear end which can measure pressures

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
