Dell Children’s Colorectal Center

Dell Children’s Colorectal and Pelvic Reconstruction Center

The Colorectal Center is for children born with a disorder of the colon or rectum who experience constipation and/or fecal incontinence.  We have specialists from pediatric surgery, gastroenterology, urology, psychology and neurosurgery to help children and families with these complex issues to achieve a goal of predictable bowel movements to improve quality of life through our multidisciplinary bowel management program.  We can help your child from a newborn into adulthood as they grow and their needs change.

Bowel Management Program

This program is designed to avoid bowel accidents and diaper dependence which can lead to remaining clean and improves self-esteem. We offer daily feedback via email and telephone to achieve individualized goals identified at your initial meeting.

Fecal incontinence can be a result of congenital conditions, constipation, or issues with muscle weakness or injury. Symptoms of this can be mild leakage of stool when passing gas to no control of bowel movements with daily accidents. Some congenital conditions our program will be successful for are:

  • Imperforate anus/anorectal malformation
  • Hirschsprung Disease
  • Idiopathic constipation
  • Fecal incontinence
  • Cloaca Exstrophy
  • Spina Bifida

What To Expect

Your family will meet with the team to review the past medical and surgical history and type of bowel control issues your child is experiencing. After a physical exam and radiographic imaging, an individualized program will be created to achieve the goals of bowel control discussed for your child. This can be achieved with dietary changes, medications such as laxatives, and/or enemas. We understand the importance of daily communication, dedication, and teamwork between our medical providers and families to achieve success.
