Meckel's diverticulum

  • Definition
    • A Meckel's diverticulum is a pouch on the wall of the lower part of the intestine that is present at birth (congenital). The diverticulum may contain tissue similar to that of the stomach or pancreas.

  • Causes
    • A Meckel's diverticulum is tissue left over from when the baby's digestive tract was forming before birth. A small number of people have a Meckel's diverticulum. However, only a few develop symptoms.

  • Symptoms
    • Symptoms may include:

      • Pain in the abdomen that can be mild or severe
      • Blood in the stool
      • Nausea and vomiting

      Symptoms often occur during the first few years of life. However, they may not start until adulthood.

  • Exams and Tests
  • Treatment
    • You may need surgery to remove the diverticulum if bleeding develops. The segment of small intestine that contains the diverticulum is taken out. The ends of the intestine are sewn back together.

      You may need to take iron supplements to treat anemia. You may need a blood transfusion if you have a lot of bleeding,

  • Outlook (Prognosis)
    • Most people recover fully with surgery.

  • Possible Complications
    • Complications may include:

      • Excess bleeding (hemorrhage) from the diverticulum
      • Folding of the intestines (intussusception), a type of blockage
      • Peritonitis
      • Tear (perforation) of the bowel at the diverticulum
  • When to Contact a Medical Professional
    • See your health care provider right away if your child passes blood or bloody stool or has ongoing abdominal pain.
