Use of High Resolution Colonic Manometry in Studying Motility

September 22, 2021 updated by: Dr. Mark Korsten, James J. Peters Veterans Affairs Medical Center

Safety and Efficacy of High Resolution Manometry in Studying Colonic Motility and Iontophoretic Administration of Prokinetic Agents

An injury to the spinal cord (SCI) results in numerous medical complications, including gastrointestinal (GI) function. Individuals with SCI may experience severe constipation (prolonged stool retention), incontinence (accidents), and overall difficulty in bowel evacuation. While various treatments and medications have been established to address this complication, there is little knowledge relating to the overall colonic motility. However, new technology such as High Resolution Colonic Manometry allows physicians to visualize high pressure contractions inside the colon, leading to a greater understanding of typical motility, a more accurate diagnosis, and an effective treatment. In this study, the investigators propose to use this technology to understand the effects of SCI on colonic motility by comparing to normal colonic function observed in able-bodied (AB) individuals. In addition, the investigators plan to study the effects of pharmacological treatments, such as neostigmine, on promoting peristaltic contractions in the colon as it is delivered across the skin.

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.

Detailed Description

The investigators data suggests that the fundamental consequence of SCI is a slowing of intestinal peristaltic activity, most likely as a result of down regulation of parasympathetic neural pathways. Furthermore, the investigators have effectively shown that measures involved in increase parasympathetic stimulation results in efficient bowel evacuation and improved bowel care. Such measures include the administration of neostigmine (NEO), which increases peristaltic contractions in the colon, resulting in predictable bowel evacuations. Given the cardiopulmonary side-effects of NEO, an ant-cholinergic known as Glycopyrrolate (GLY) is usually co-administered with NEO to reverse these side effects. However, the investigators knowledge regarding the effects of SCI on colonic motility is still primitive, mainly due to pervious technological disadvantages. New High Resolution Colonic Manometry systems (Medical Measurement Systems Dover, NH) simultaneously capture high amplitude pressure contractions (HAPCs) across the ascending, transverse, descending, and recto-sigmoid colon. Such capabilities allow for a much clearer display of pressure events compared to previous line tracing manometric systems and the direction of contractions are much easier to discern as well. To date, this technology has been an effective tool in diagnosing bowel disorders and complications, such as constipation in able-bodied individuals (AB). However, such studies have not been conducted in a SCI population. This technology also has the potential to capture the effects of NEO+GLY on improving colonic function.

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

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.
