Trial summary

The portal hypertension (PHT) is the main complication in patients presenting with cirrhosis. It can be the direct cause of bleeding by rupture of the esophageal or gastric varices and can also contribute to the development of ascites, hepatic encephalopathy and pleuropulmonary complications.

About this study

Official title: Evaluation of Wireless Capsule Endoscopy for the Detection and the Control of the Esophageal Varices in Children

The portal hypertension (PHT) is the main complication in patients presenting with cirrhosis. It can be the direct cause of bleeding by rupture of the esophageal or gastric varices and can also contribute to the development of ascites, hepatic encephalopathy and pleuropulmonary complications.

In the paediatric population presenting with the PHT, one of every two children develops varices and thus has a significant risk of bleeding. Safe and easy to use, the video capsule endoscopy (VCE) is now routinely used in children for the exploration of the small bowel. But the role of the VCE for examination of the other parts of digestive tract still needs to be evaluated.

For the esophagus, the VCE could allow the diagnosis without the need of general sedation. Recent studies have shown a good sensitivity and tolerance of this technique for the initial diagnosis of esophageal varices (EV) in adult patients presenting with portal hypertension, but it has not yet been validated for this indication.

The investigators hypothesize that the VCE could be used in children with similar results in term of efficacy, as for adults.

This prospective simple blind multicentre study (blind for the lecture of the capsule endoscopy record), will investigate the diagnostic value of the VCE compared to the conventional esophagogastroduodenoscopy (EGD) under general sedation for the detection and the control of esophageal varices in children.

If it is provided that the VCE is as efficient as it is for the adults, it could become a very interesting alternative to the conventional EGD because less expensive and less invasive. Moreover, this technique would be very useful as a means of early detection on the EV and/or their control.

What participants receive

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

  • Wireless esophageal capsule endoscopy ( PillCam Eso2)Device

    Also called PillCam Eso2

    This is a simple blind (blind for the lecture of the capsule endoscopy record) study to evaluate the diagnostic value of the capsule endoscopy for the detection and the control of esophageal varices, the feasibility, tolerance and safety of the capsule endoscopy compared to the conventional EGD under general sedation in children presenting with portal hypertension.

    During one week, the patients will undergo two exams (capsule endoscopy and EGD under general sedation). The exams will be done by two different physicians.

    For to asses the tolerance, after they completed both exams, the patients will be asked to answer a "comfort score" questionnaire.

    In order to asses the safety of the capsule endoscopy, the patients will be followed for adverse events during 3 weeks after the completion of the capsule endoscopy.

What is being measured

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

  1. Diagnostic value of the wireless capsule endoscopy

    The diagnostic value of the wireless capsule endoscopy as measured by the sensitivity of the wireless capsule endoscopy for the detection and the control of esophageal varices in children compared to the EGD sensitivity.

    Measured: 1 week

Secondary outcomes (4)
  1. Diagnostic value comparing the specificity, the positive and negative predictive value (PPV, NPV) of the wireless capsule endoscopy

    Diagnostic value comparing the specificity, the positive and negative predictive value (PPV, NPV) of the wireless capsule endoscopy with the results for the EGD under general sedation.

    Measured: 1 week

  2. Feasibility and safety of the wireless capsule endoscopy

    Feasibility and safety of the wireless capsule endoscopy compared to the conventional EGD under general sedation as expressed by the safe completion of the wireless capsule endoscopy.

    Measured: 4 weeks

  3. Acceptance of the wireless capsule endoscopy

    Acceptance of the wireless capsule endoscopy by the patient compared to the EGD under general sedation by calculating a comfort score.

    Measured: 1 week

  4. Applicability of the wireless capsule endoscopy

    Applicability of the wireless capsule endoscopy by evaluating the ability to detect the esophageal or fundic varices, the presence of a portal hypertension gastropathy and the classification of the esophageal varices compared to the EGD results.

    Measured: 1 week

Questions about this trial

What is this clinical trial studying?

A study testing Wireless esophageal capsule endoscopy ( PillCam Eso2) in people with Portal Hypertension and Cirrhosis, run by Hospices Civils de Lyon at 7 sites in France.

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 5 inclusion and 7 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 28 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in France. 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?

Diagnostic value of the wireless capsule endoscopy (time frame: 1 week). 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 NCT01551966, which also lists 1 linked publication.

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 28 May 2019.
