Aandoening
This will be a prospective study comparing two imaging techniques. MR enteroclysis will be performed at the department of Radiology of the Medical Centre Alkmaar. The double-balloon enteroscopy and videocapsule will be performed at the department of Gastroenterology of the Medical Centre Alkmaar and the department of Gastroenterology and Hepatology of the Erasmus Medical Centre Rotterdam.

diagnostic yield, including location and nature of lesions. The pathologic findings in the small bowel of the different diagnostic methods will be correlated with each other to analyse location and nature of lesions. For patients with known or suspected Crohn’s disease of the small bowel, a comparison will be made for prevalence, location, severity of inflammatory lesions, and complications such as formation of stenotic lesions. For patients with gastrointestinal blood loss, the techniques will be compared for prevalence and location of bleeding foci and characters of the lesion. The findings at the double balloon endoscopy will be used as the gold standard.
Achtergrond van het onderzoek
Rationale:
There has been no study so far that compared videocapsule endoscopy and MR enteroclysis for common small bowel diseases and especially not with the improved reference standard double ballon endoscopy. Such a comparison is highly needed to select appropriate techniques for individual patients. Because the double balloon endoscopy is in accordance with standard endoscopy, it can be used as a gold standard method.
Objective:
Comparison of two new techniques for detection of small bowel pathology: MR enteroclysis and videocapsule enteroscopy with double-balloon enteroscopy with respect to diagnostic yield, accuracy of findings, and patient preference.
Study design:
This will be a prospective study comparing two imaging techniques. MR enteroclysis will be performed at the department of Radiology of the Medical Centre Alkmaar. The double-balloon enteroscopy and videocapsule will be performed at the department of Gastroenterology of the Medical Centre Alkmaar and the department of Gastroenterology and Hepatology of the Erasmus Medical Centre Rotterdam.
Study population:
A total of 80 patients with suspected small bowel disease across 2 hospitals in the Netherlands will be included in this multicenter study; 40 patients with proven or suspected Crohn’s disease, and 40 patients with signs of chronic or repeated gastrointestinal bleeding with negative gastroscopy and colonoscopy
Main study parameters/endpoints:
diagnostic yield, including location and nature of lesions. The pathologic findings in the small bowel of the different diagnostic methods will be correlated with each other to analyse location and nature of lesions. This will assessed in two populations:
1. Patients with known or suspected Crohn’s disease.
2. Patients with signs of chronic or repeated gastrointestinal bleeding with negative gastroscopy and colonoscopy.
Patients’ appreciation of the different diagnostic methods. This will be analysed by means of a questionnaire.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness:
MR enteroclysis: The dosis radiation received in order to place the nasogastric tube is very small (less than one X-ray of the Thorax).
Videocapsule: While swallowing, the videocapsule does not cause any side effects. If stenosis of the bowel is suspected, a test capsule is swallowed, which can fall apart in the small bowel.
Double-balloon endoscopy: The chance of complications as a result of the endoscopy is less than 1 per 1000 endoscopies
Doel van het onderzoek
