 The definite difference between the architecture of the mucosal surfaces in the small intestine and other gastrointestinal organs(esophagus, stomach and large intestine)is that only the small intestine has minute mucosal projections called villi. Villi disturbe endoscopic observation of the intestinal gland orifices which are called crypts of Lieberkuhn.

 Therefore, observation of “pit pattern”, which is formed by the shape and arrangement of crypts, is generally impossible by means of magniying endoscopy. Only a very high grade of villous atrophy or small intestinal lesions without villous artitecture allow observation of “pit pattern”.

 In enteroscopy combined with magnifying endoscopy, the most important finding is the shape of villi.
