Evaluation of 3-Dimensional Magnetic Imaging During Colonoscopy

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00258531
Recruitment Status : Completed
First Posted : November 24, 2005

Brief Summary:
  • A commercial 3-dimentional magnetic imaging system (Olympus ScopeGuide) is available for routine use during colonoscopy.
  • No randomised trials have been performed to evaluate if, and to what extent, the use of this technology may improve the coecal intubation rate and reduce the patient's experience of discomfort and pain by making the insertion of the endoscope easier

Condition or disease Intervention/treatment Phase
Any Symptom Requiring Colonoscopy Device: Olympus ScopeGuide®, 3-dimentional magnetic imager Phase 4

Detailed Description:
Endoscopist at different level of experience are to participate. Patients routinely referred to the outpatients department for colonoscopy are asked to participate in a randomised trial where coecal intubation rate and pain experienced by the patient are end-point. Written informed consent is obtained. For each endoscopist, allocated patients are randomised to colonoscopy with no imaging technique (usual care) or using the 3-dimentional imager.
