Mucosal morphologic alterations in Thiry-Vella fistulas. 1976

W H Halliwell, and D A Schmidt, and D P Hutcheson

Three Thiry-Vella fistulas were surgically placed in each of 9 dogs to study the effects of x-irradiation on isolated loops of small intestine. Mucosal biopsy samples were removed from the fistulas for 5 days at 24-hour intervals after surgical operation to assess the morphologic alterations that occurred in the fistula mucosa following surgical isolation. There was a reduction of villus height during the 1st day, reduction of crypt depth on days 2 and 3, and stabilization of villus height and crypt depth during days 3 to 5 after surgical operation. The surgical technique and morphologic alterations observed in the mucosa of the fistulas during the 5 days after surgery are described.

UI	MeSH Term	Description	Entries
D007412	Intestinal Fistula	An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).

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
