Ileocecal Sphincter Reflex by Cecal Distension During Colonoscopy
An observational study of Irritable Bowel Syndrome, run by Northwell Health at 1 site in United States.
Trial summary
The aim of the current study is to test the hypothesis that patients with IBS may have a defective ICV pressures and may have small bowel bacterial overgrowth. The goal of the current study is to identify the role and competence of ileocecal valve (ICV) in patients with irritable bowel syndrome. Read more about this study

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 20 to 80 years
- All sexes
- Healthy volunteers accepted
- Adult, Older adult
Study population: Patients with who are undergoing routine screening colonoscopies.
Who may be able to join
- Patients with a history of small bowel bacterial overgrowth or irritable bowel syndrome and who are undergoing routine colonoscopies or subjects who are undergoing routine colonoscopy and test positive for small bowel bacterial overgrowth will be candidates. If the patient has prior lactulose breath test done for clinical purposes then repeat lactulose breath test will not be required. If no prior lactulose breath test has been performed then it will be done as part of this research study. In addition patients who test negative for SBBO will be candidates for the control population.
Who cannot join
- Medications-Subjects on any medication that could affect the ileocecal valve high-pressure zone will be excluded; this includes use of prokinetic agents, current use of any antibiotics and anticholinergics. Patients will be excluded if the lactulose breath test is done on antibiotics or during the colonoscopy preparation.
- GI symptoms, conditions and disorders: In addition exclusion criteria will include a history of ileocecal resection or disease affecting the colon and/or small bowel including crohn's disease, ulcerative colitis or diseases causing diarrhea.

About this study
Official title: Evaluation of the Ileocecal Valve in Patients With and Without Irritable Bowel Syndrome.(IBS)
The aim of the current study is to test the hypothesis that patients with IBS may have a defective ICV pressures and may have small bowel bacterial overgrowth. The goal of the current study is to identify the role and competence of ileocecal valve (ICV) in patients with irritable bowel syndrome.
The primary objective is to measure the pressure of the ileocecal valve in patients with and without irritable bowel syndrome (IBS). The Ileocecal valve reflux pressures during air insufflation of cecum will be used.
Read the detailed description
This is an outpatient study. There will be no requirement to stay overnight in the hospital. The research will be conducted in the gastroenterology section of the department of Medicine in North shore university hospital and in North shore long island Jewish medical center. Both these hospitals are tertiary care centers with adequate facilities for the safe and appropriate conduct of this research. Participants must meet all eligibility criteria and sign the consent form before enrolling in the study. This is a cohort study with 2 groups (patients with IBS and participants without IBS). Patients will be enrolled into one of these two categories based on their medical history, signs and symptoms and questionnaire. There are no controlled compounds used in this study. There is no treatment involved in this study. There are 2 study related visits per subject.
Based on questionnaire we plan to recruit 25 participants who meet the criteria of IBS and 25 participants who do not meet the criteria of IBS (Total of 50 participants in the study). Patients with IBS are those who meet the criteria of IBS based on their symptoms and the responses to a validated ROME III - questionnaire. All other participants who do not meet the criteria for IBS are classified as non-IBS participants. All the participants should be having a clinically indicated colonoscopy.

Questions about this trial
What is this clinical trial studying?
An observational study of Irritable Bowel Syndrome, run by Northwell Health at 1 site in United States.
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 1 inclusion and 2 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: stopped early, as of the sponsor's last update on 22 Feb 2019. 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 United States. 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 was stopped early (reason given: Not able to enroll enough patients in this study). Results are not available in the source record.
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?
Pressure generated in ICV during Cecal distention (time frame: 10-15 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01413945, which also lists 11 linked publications.
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 22 Feb 2019.
