[Colonic sphincters--Hirsch's sphincter].
Anatomic and physiological sphincters of the colon are localized narrowness of the colon with adequate name. These sphincters appear due to the thickening of longitudinal and circular muscle fibers in the wall of colon or due to the reflex irritation of the autonomous nervous system which innervates the colon. If they appear isolated, their radiographs look similar to those of an organic stenose of the colon. This leads to a false diagnosis and the patient has to undergo an operation. It is not so rare to find the sphincter of the colon instead of a malignant process during the operation. The authors present a patient with Hirch's sphincter of the colon addressed to their institution with the diagnosis: Tucoli ascendentis based on irrigoscopy and irrigography previously performed in another institution. On repeated irrigoscopy and irrigography with double contrast in hopotonia with Glucagon the ascendent part was clearly enlarged with normal wall contours and mucous pattern. The patient had been discharged with the diagnosis of anatomic Hirsch's sphincter and she is in quite good condition.
