An ileostomy is a small opening (or stoma) surgically created in the abdominal wall through which the end of the small intestine, the ileum, is brought to the skin's surface to function as an anus after being surgically disconnected from the large intestine. a bag is attached to the opening to allow waste to drain into the bag. Patients who have this procedure enjoy improved quality of life and health, as there are no activity restrictions with an ileostomy. Patients can work, play sports, and eat out (activities that were often difficult with the active disease).

Ileoanal Anastomosis or Pouch Procedure

An ileoanal anastomosis, also called a "pull-through operation" or a J pouch, avoids the use of a permanent bag to drain waste from the colon. This procedure is often used as an alternative to a permanent ileostomy and is completed in two surgeries. First, the diseased colon and rectum are removed, preserving the anal muscles necessary for bowel control, and a temporary ileostomy is performed. Second, the ileostomy is closed and part of the small intestine is used to create an internal pouch to hold stool. This pouch is attached to the anus. The muscle of the rectum is left in place, so the stool in the pouch does not leak out of the anus. People who have this surgery are able to control their bowel movements, although they may be more frequent and watery than usual.

The main complications of the ileoanal anastamosis include pouchitis (inflammation of the J pouch), infection, and bowel obstruction. Some patients experience a mild amount of anal leakage as well, due to the liquid nature of the stool. Despite these complications, over 90% of patients who have undergone an ileoanal pouch consider their quality of life to be excellent, and would make the same decision to undergo the procedure again.

Patients usually have a choice of whether to have a permanent ileostomy or an ileoanal anastomosis. Both surgeries are effective and can help restore quality of life.

Image-Guided Biopsy

An image-guided biopsy is a procedure in which the doctor uses imaging technology, such as ultrasound, fluoroscopy, a computed tomography (CT or CAT) scan, x-ray, or a magnetic resonance imaging (MRI) test, to determine the exact location where the tissue sample will be removed for analysis.


Also called biologic therapy, Immunotherapy is designed to boost the body's natural defenses to fight the cancer. It uses materials either made by the body or in a laboratory to bolster, target, or restore immune system function.
