Intestinal Abnormalities clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Diagnosis of Intestinal Motility by Image Analysis Using Capsule Endoscopy

Start date: February 2009
Phase: N/A
Study type: Interventional

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.
