Usefulness of High Resolution Manometry in Constipation (MANOCOHR)

February 5, 2026 updated by: University Hospital, Rouen
Constipation is a frequent symptom that is reported by more than 10% of the general population. In a few case, constipation is resistant to medical standard care, including osmotic and stimulant laxatives. The diagnosis of colonic inertia may be suspected in these patients although diagnostic criteria for colonic inertia may vary from one country to another. In France, the diagnosis of colonic inertia is based on manometric study of the colorectal contractile activity using manometric probe. Using conventional manometric catheters, severe alteration of the colorectal motility is found in a very small subset of patients, who may later benefit from surgery. The recent use of high resolution manometric probe allowed to map more precisely colorectal motility, but whether these new parameters are relevant remains to be assessed. The aim of this study is to assess the diagnostic performance of a new high resolution manometric probe by comparing healthy volunteers to patients suspected of colonic inertia.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
76

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes
