Scanning electron microscopy of small intestinal repair following treatment for gluten sensitive enteropathy. 1980

S A Halter, and H L Greene, and G Helinek

Sequential small intestinal biopsies from patients with gluten sensitive enteropathy were studied by scanning electron microscopy before and after dietary treatment. Compared with patients without evidence of villus atrophy, there were marked architectural changes. Before treatment, villi were absent and crypts were prominent. After treatment, the intestinal repair could be divided into stages. The first stage consisted of circular ridges surrounding the crypts. Unequal cellular repletion around the crypts resulted in the formation of horseshoe shaped ridges. Elongation of the arms of the horseshoes led to the formation of cerebriform ridges. Mitten-like villi were formed in the last stage by the development of furrows and septation of the ridges. The scanning electron microscope is a useful adjunct to the light microscopic and dissecting microscopic assessment of small intestinal biopsies. It can detect changes not possible with either light microscopy or the dissecting microscope and may be a more sensitive technique for the morphological assessment of patient response to treatment for gluten sensitive enteropathy.

UI MeSH Term Description Entries
D007413 Intestinal Mucosa Lining of the INTESTINES, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. In the SMALL INTESTINE, the mucosa is characterized by a series of folds and abundance of absorptive cells (ENTEROCYTES) with MICROVILLI.

D007421 Intestine, Small The portion of the GASTROINTESTINAL TRACT between the PYLORUS of the STOMACH and the ILEOCECAL VALVE of the LARGE INTESTINE. It is divisible into three portions: the DUODENUM, the JEJUNUM, and the ILEUM. Small Intestine,Intestines, Small,Small Intestines
D008855 Microscopy, Electron, Scanning Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.

D009093 Mucus The viscous secretion of mucous membranes. It contains mucin, white blood cells, water, inorganic salts, and exfoliated cells.
D002446 Celiac Disease A malabsorption syndrome that is precipitated by the ingestion of foods containing GLUTEN, such as wheat, rye, and barley. It is characterized by INFLAMMATION of the SMALL INTESTINE, loss of MICROVILLI structure, failed INTESTINAL ABSORPTION, and MALNUTRITION.
