<unk>  to show the location of the ileocecal valve on the most distal cecal fold. The<unk>  is an endoscopic sign for determining the location of the ileocecal valve during colonoscopy. Identifying the ileocecal valve in a colonoscopy is important, as it indicates that the entire colon has been visualized. The identifiable landmarks in the cecum are the appendiceal orifice—which is a curvilinear indent indicating the location of the appendix from the lumen of the<unk> el—and the ileocecal valve, which appears as a puckering in the most distal fold of the cecum. The<unk>  uses the curve of the appendiceal orifice to point toward the direction of the ileocecal valve, as if it were a<unk>  guiding an<unk> . The colonoscope can be passed in this direction in order to enter the terminal ileum. This is used as one of two identifiable landmarks of the colon (the other being the anus), and signifies that the entire colon has been visualized.
