%X Seventy-five consecutive patients were identified with a delayed or unnoticed delivery of the test capsule. Seventy patients consented to participate and underwent MRE (44) or CTE (26). The medical records and imaging studies were retrospectively reviewed and symptoms, laboratory results and imaging findings recorded.Lesions compatible with Crohns disease were shown by MRE in 5 patients, by CTE in one and by VCE in four, one of whom had lesions on MRE. In patients without alarm symptoms and findings (weight loss, haematochezia, anaemia, nocturnal diarrheoa, ileus, fistula, abscess and abnormal blood tests) imaging studies did not unveil any such lesion. VCE's were performed in only 20 patients, mainly younger than 50 years of age, although no stenotic lesion was shown by MRE and CTE. In the remaining 50 patients no VCE or other endoscopic intervention was performed indicating that the referring physician was content with the diagnostic information from MRE or CTE.The diagnostic value of MRE and CTE is sufficient for clinical management of most patients with suspected small bowel disease, and thus VCE may be omitted or at least postponed for later usage.The least invasive imaging tool that demonstrates the mucosa of the whole small bowel in detail is the video capsule for enteroscopy (VCE). The capsule is an environmentally friendly, high-tech miniature endoscope, designed to be swallowed for spontaneous passage through the small bowel. VCE soon established itself as a first-line diagnostic procedure of small bowel diseases [1,2] although it carries a small risk of the capsule getting stuck in a stenosis. In order to avoid this calamity, a self-disintegrating sham capsule, known as the patency capsule (PC) and equal in size and shape to the video capsule, was soon introduced to prove a non-obstructed small bowel passage. The capsule is naturally excreted within 18 hours. If not noted, a dedicated screening tool for external abdominal application is used to trace it.
