"Your doctor may recommend a subtotal colectomy if your colon is diseased and must be entirely removed, but your rectum is unaffected by Crohn’s disease.

  • Once your colon is removed, your surgeon will join the ileum, or the lower part of your small intestine, to the rectum.

  • A colectomy allows you to continue to pass stool through your anus without the need for an external pouch."
