Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This prospective, open-labelled, longitudinal, controlled study aims to evaluate the suitability of Intermittent Colonic Exoperistalsis (ICE) treatment for adults with refractory chronic constipation who are awaiting trans-anal irrigation (TAI). The ICE treatment will be applied using the MOWOOT device (USMIMA). The study involves two treatment groups: an experimental group receiving daily ICE treatments and a control group following standard TAI care. Participants will serve as their own controls in pre- and post-treatment analyses to assess changes in bowel management satisfaction and other outcomes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a prospective, open-labelled, longitudinal, controlled trial conducted at a single center. It aims to assess the suitability of Intermittent Colonic Exoperistalsis (ICE) treatment for bowel management in adults with refractory chronic constipation who are awaiting trans-anal irrigation (TAI). The ICE treatment will be applied using the MOWOOT device (USMIMA). The study includes two treatment groups:

Experimental ICE Group: Participants will receive one ICE treatment session lasting 20 minutes daily, at the same hour, for 12 weeks.

Control TAI Group: Participants will follow the usual TAI standard-of-care treatment for 12 weeks.

Participants will be given the option to choose between the ICE treatment and the TAI treatment after both options are explained to them. Healthcare professionals will recommend the most suitable treatment based on individual patient needs, but the final decision will rest with the patients.

The primary objective is to evaluate the change in satisfaction with daily quality of life related to bowel management, measured by a Likert scale (Bothersome scale). Secondary objectives include assessing the efficacy of the ICE treatment on chronic constipation, both qualitatively and quantitatively, and evaluating the economic impact from the hospital's perspective.

Secondary outcomes will be measured through various patient-reported and health professional-reported metrics, including changes in quality of life (PAC-QOL), constipation symptoms (PAC-SYM), constipation severity (CCCS), time spent in bowel management and evacuation, use of other treatments, number of consultations and hospital admissions, productivity, acceptability and ease of use of the ICE treatment, reported problems, compliance, adherence, and persistence in treatment. Health professional outcomes will include time spent per visit, total time spent until independent use of MOWOOT, ease of patient management, and patient treatment preferences.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

This is a prospective, open-labelled, longitudinal, controlled study, with two treatment groups, performed at one single centre. For both groups, patients will be their own control in the pre and post analysis of primary and secondary outcomes.
Primary Study Purpose

TREATMENT

Blinding Strategy

NONE

This is an open-label study, meaning there is no masking. Both the participants and the researchers are aware of the treatment being administered. This approach is necessary due to the nature of the intervention, which makes blinding impractical.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental ICE Group

Each patient will receive 1 ICE treatment of 20 minutes at least once per day, every day at the same hour, during the intervention period of 12 weeks.

Group Type EXPERIMENTAL

ICE Treatment

Intervention Type DEVICE

Each patient in the Experimental ICE Group will receive one Intermittent Colonic Exoperistalsis (ICE) treatment session lasting 20 minutes. These sessions will be conducted at least once per day, every day at the same hour, for a total duration of 12 weeks. The ICE treatment involves using the MOWOOT medical device designed to alleviate chronic constipation by stimulating colonic peristalsis.

Control TAI Group

Each patient will follow the usual TAI standard-of-care treatment for the intervention period of 12 weeks.

Group Type ACTIVE_COMPARATOR

TAI Standard-of-Care Treatment

Intervention Type PROCEDURE

Each patient in the Control TAI Group will follow the usual Trans-Anal Irrigation (TAI) standard-of-care treatment. This involves the regular use of TAI procedures as prescribed by healthcare professionals for the intervention period of 12 weeks. The TAI treatment is a well-established method for managing chronic constipation by mechanically clearing the bowel.
