AIM: To prove that the terminal ileum is intussuscepted into the cecum creating the ileocecal junction, contrary to previous valvular concept which has been widely believed. METHODS: This study is based on gross and microscopic examinations of fresh specimens derived from colonic operations (right hemicolectomy or subtotal colectomy). Data compiled from observing and dissecting of specimens of seven patients are used to examine both gross and microscopic appearance of ileocecal junction. RESULTS: Intussusception of the terminal ileum was found in every specimen. However, the length of intussusception was different in each specimen. CONCLUSION: Gross and microscopic appearance studies suggest that the terminal ileum is intussuscepted into the cecum.
