About this study

Official title: Intestinal Motility Evaluation by Endoluminal Image Analysis Using Capsule Endoscopy (CE-EIA): a Multi-center Clinical Trial

Conventional intestinal manometry is the current gold standard for the evaluation of intestinal motility, and identifies patterns of intestinal dysmotility. However intestinal manometry involves intestinal intubation with consequent discomfort for the patients, and requires considerable technical expertise and knowledge for interpretation of the data. Hence, to date this method has limited indications and is restricted to very few referral centers around the world.

A novel method for evaluation of intestinal motility has been developed based on endoluminal image analysis using the endoscopic PillCam capsule, In contrast to manometry, this technique is minimally invasive, the technical aspects are simple, and the analysis is fully automated by a computer program.

The technique has been validated in a group of patients with intestinal dysmotility and healthy subjects, and has demonstrated over 90% sensitivity and specificity.

This technique needs now to be validated in a large multinational population, to further develop a robust discrimination algorithm for widespread diagnostic application. Furthermore, whereas manometry only recognizes neuropathic, myopathic and obstructive motor patterns, endoluminal image analysis may identify different categories of patients depending on the clinical presentation and the etiologic factors involved.

This study is designed to provide evidence that the algorithm, using images created by PillCam SB2 capsules, is at least as good as small bowel manometry in diagnosing severe dysmotility.

Read the detailed description

Conventional intestinal manometry is the current gold standard for the evaluation of intestinal motility1,2,3,11, and identifies patterns of intestinal dysmotility4,8,9. However intestinal manometry involves intestinal intubation with consequent discomfort for the patients. Furthermore, it requires considerable technical expertise and knowledge for interpretation of the data. Hence, to date this method has limited indications and is restricted to very few referral centers around the world6,7,10,13.

Vall d'Hebron Hospital, in collaboration with CVC (Barcelona, Spain) have recently developed a minimally invasive method for evaluation of intestinal motility based on endoluminal image analysis using the endoscopic PillCam capsule. In contrast to manometry, this technique is minimally invasive, the technical aspects are simple, and the analysis is performed fully automated by a computer program. Both the technical procedure of the test and the endoluminal image analysis program has been developed by a multidisciplinary medical-engineering team in the Autonomous University of Barcelona over the past 5 years. The technique has been validated in a group of patients with intestinal dysmotility and healthy subjects, and has demonstrated over 90% sensitivity and specificity.

In brief, the technique works as follows. In each study a series of features are analyzed: contractile patterns (contractions evaluated as a diaphragmatic occlusion of the lumen and by the presence of a radial wrinkle pattern), non contractile patterns (wall and tunnel patterns), luminal content (turbid pattern), endoluminal motion, and capsule displacement.

The program is based on an automated learning method (machine learning technique). Data from patients and healthy subjects are used as a training set. Based on these data, the program develops the function that best discriminates both groups. The performance of the system has been validated using the leave-one-out method that uses all but one as training set and evaluates the left-out example.

This technique needs now to be validated in a large multinational population. Using this expanded pool of studies as a learning set, a robust discrimination algorithm will be developed, that can be made available for widespread diagnostic application. Furthermore, whereas manometry only recognizes neuropathic, myopathic5,12 and obstructive motor patterns, endoluminal image analysis may identify different categories of patients depending on the clinical presentation and the etiologic factors involved.

This study is designed to provide evidence that the algorithm, using images created by PillCam SB2 capsules, is at least as good as small bowel manometry in diagnosing severe dysmotility.

What participants receive

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

  • PillCam SB2Device

    The disposable, ingestible PillCam SB 2 Capsule, part no. FGS-0180, is designed to acquire video images during natural propulsion through the small bowel. The capsule transmits acquired images via RF communication channel to the DataRecorder located outside the body.

What is being measured

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

  1. To Evaluate Accuracy of Endoluminal Image Analysis by Capsule Endoscopy in Detecting Severe Dysmotility

    Patients were indicated for small bowel manometry based on one or both of the following symptoms:

    • Pseudo obstruction
    • Unintentional body weight loss

    Measured: Up to 7 months

Secondary outcomes (1)
  1. To Assess Correlation Between Patient Clinical Symptoms and CE-EIA

    The study was terminated without achieving the needed sample size due to very low recruitment rate. Therefore, no statistical analysis has been performed to achieve the secondary outcome.

    Measured: Up to 7 months

Questions about this trial

What is this clinical trial studying?

A study testing PillCam SB2 in people with Intestinal Abnormalities, run by Medtronic - MITG at 6 sites in 5 countries.

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 23 inclusion and 13 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 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States, Belgium, Italy, Spain, Sweden. 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?

Yes. Results are posted in the registry (first posted 23 Jun 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

To Evaluate Accuracy of Endoluminal Image Analysis by Capsule Endoscopy in Detecting Severe Dysmotility (time frame: Up to 7 months). 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 22 Jul 2020.
