“…It is recommended that patients avoid magnetic fields such as magnetic resonance imaging (MRI), and metal detectors until the capsule is excreted in the stool, which usually occurs in 24-48 h. Small bowel preparation is still a controversial issue. Some groups used fasting or clear liquids for 10 to 12 h (or even for 24 h) before the study, although some studies suggest that bowel preparation (with 2 or 4 liters of polyethylene glycol based electrolyte solution or oral sodium phosphate preparation) improves the visualization of the small intestine (Dai et al,2005;de Franchis et al,2005).A recent Spanish prospective multicenter trial published in abstract form, has shown that all three strategies have similar results (Pons et al,2006). After ingestion of the capsule, patients were allowed to drink clear liquids after 2 h and eat a light meal after 4 h and were observed for 8 h at the study site.…”
