	The '''ileocecal valve''', abbreviated '''IC valve''', is the divider between the [[small bowel]] and cecum. It is seen by pathologist in some subtotal colectomies (e.g. right hemicoloectomies) and occasionally biopsied.

			COMMENT:
			The clinical history (prominent ileocecal valve) is noted. No adipose tissue is seen in
			this superficial mucosal biopsy.

			The inflammation is focal and superficial, and blunted-appearing villi are present. The
			changes may be due to mechanical factors; however, other causes should be considered
			clinically.
