About this study

Official title: Long-term Efficacy of Sacral Nerve Stimulation for Irritable Bowel Syndrome. A Randomised Controlled Crossover Study

A recent randomised, controlled, crossover study has shown that sacral nerve stimulation (SNS) significantly reduces symptoms and improves quality of life of highly selected patients with irritable bowel syndrome (IBS). Relief of IBS symptoms during SNS is associated with consistent changes in rectal sensitivity and biomechanical wall properties.

The aim of the present study is to evaluate long-term efficacy of sacral nerve stimulation on symptoms and quality of life in patients with IBS in a randomised, placebo-controlled, crossover study.

Read the detailed description

Twenty two patients with IBS-D or IBS-M according to the ROME III criteria, will be enrolled by invitation in the study.

Having meet inclusion criteria, the patients are first set subsensory for 4 weeks and then randomised to receive either OFF-subsensory or subsensory-OFF stimulation in a 4+4-week period.

During the PNE test the effect of the stimulation is evaluated by specific IBS symptom and quality of life questionnaires (GSRS-IBS and IBS-IS) and bowel habit diaries.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SubsensoryDevice

    Also called Device: External pacemaker, model 3625, Medtronic Inc.

    The stimulation is set to 90% of the sensory threshold.

  • OFFDevice

    Also called Device: External pacemaker, model 3625, Medtronic Inc.

    The stimulation is turned OFF.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Gastrointestinal Symptom Rating Scale - Irritable Bowel Syndrome version

    The questionnaire is filled in every week of the 12 week study period

    Measured: Change in the IBS-specific symptom score between the subsensory and the OFF period in the crossover study

Secondary outcomes (1)
  1. Irritable Bowel Syndrome - Impact Scale questionnaire

    The questionnaire is filled in every week of the 12 week study period

    Measured: Change in the IBS-specific quality of life score between the subsensory and the OFF period in the crossover study

Questions about this trial

What is this clinical trial studying?

A study testing Subsensory and OFF in people with Irritable Bowel Syndrome, run by University of Aarhus at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Gastrointestinal Symptom Rating Scale - Irritable Bowel Syndrome version (time frame: Change in the IBS-specific symptom score between the subsensory and the OFF period in the crossover study). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 May 2018.
