How the small intestine is examined – because small intestine examinations are so complex, it is difficult to describe how they are carried out.
Imaging and instrumental examinations are usually performed on an empty stomach; for the latter, the fibre-optic instrument is passed through the mouth while the patient is under anaesthesia.
Functional tests and isotope examinations are started on an empty stomach and continued after the patient has consumed test substances or test meals.
Standard blood sampling and stool testing methods form the basis of laboratory testing.
Histological examination is only possible following fibre-optic examinations.
