title: [Non-invasive methods for assessing the small intestines].
abstract: Non-invasive methods investigating small bowel functions are critically reviewed. For intestinal absorption, we discuss the value of fecal fat determination, D-xylose testing and breath tests. Intestinal bacterial overgrowth may be assessed by breath hydrogen test or 14C-D-Xylose breath test. Small intestinal transit time can be measured by a scintigraphy method or by a breath hydrogen technique. Intestinal clearance of alpha-1 antitrypsin is now the method of choice for the detection of protein-losing enteropathy. Intestinal permeability can be assessed by 51Cr-EDTA/14C-mannitol ratio or PEG 900 method.
