Figure 1 Intussusception of the terminal ileum into the cecum.

Figure 2 Reduction of the intussusceptum part of the terminal ileum from the cecal wall (blue marker). A: Point of intussusception; B: Dissection and reduction of intussusception; C: Length of intussusception, after reduction.

Figure 3 Cross section of the specimen reveals wall of the terminal ileum intussuscepted into the cecum (arrow).

Figure 4 Microscopic appearance of the ileocecal junction displays the muscular layer of the terminal ileum fold extending into the cecum.
