[Functional tests in small bowel diseases (author's transl)].
D-xylose-, Schilling-test, and fecal fat analysis are still the most important functional tests in small bowel diseases despite rapid progress in enterology. The segmental intestinal perfusion technique can be considered to be the most appropriate method at the moment to measure absorptive or secretory capacity of defined gut segments. Under well-defined conditions the tissue accumulation technique with fresh small bowel biopsy specimens may offer valuable results on absorptive capacity of the gut tissue in specialized laboratories.
