What is Meckel’s Diverticulum?

An abnormal sac or pouch that develops at a weak point in the intestines is known as a diverticulum. Various types of diverticula can develop as you age. In some instances, people are born with a diverticulum in their intestines. This condition is called Meckel’s diverticulum.

Meckel’s diverticulum develops between the 5th and 7th weeks of fetal growth. Because the condition is present at birth, it is classified as a congenital health issue.

What Are the Symptoms of Meckel’s Diverticulum?

The symptoms of Meckel’s diverticulum are related to the type of diverticulum that is present. In 95 percent of patients with this condition, the diverticulum that develops is made up of intestinal cells. As a result, the diverticulum functions as a normal part of the intestine. This type of diverticulum may not cause any significant symptoms.

In other instances, the diverticulum may be made up of stomach or pancreatic cells. When this occurs, the diverticulum will function differently from the intestines. This may result in significant symptoms, including:

  • blockage of the intestines
  • bleeding into the intestines, resulting in bloody stools
  • inflammation in the intestines
  • pain or discomfort that ranges from mild to severe
  • anemia

The symptoms that occur are often related to the age of the patient when Meckel’s diverticulum is discovered. For example, infants with the condition are more likely to have a blockage in their intestines. Intestinal bleeding and bloody stools are more common in older children with the condition.

Most cases of Meckel’s diverticulum are identified and treated in children under the age of 10. The remaining cases are typically diagnosed in adolescence.

Meckel’s diverticulum may cause sporadic symptoms. When this occurs, blood in the stool may be noted for several days. This will be followed by a period of normal stool (no blood). Erratic symptoms can make the condition difficult for your doctor to diagnose.

In rare cases, excessive bleeding from Meckel’s diverticulum may occur. In this situation, the diverticulum can become life-threatening. If this happens, emergency surgery may be needed to remove the diverticulum.

How Is Meckel’s Diverticulum Diagnosed?

If you or your child has symptoms of Meckel’s diverticulum, your physician will recommend several different tests to confirm the diagnosis. Blood tests will be ordered to determine if your red blood cell count is low. This will help your doctor determine if bleeding is occurring in the intestines. In addition, your doctor may order a stool smear. In this test, a sample of your stool will be analyzed to see if it contains blood.

Your doctor may also order a technetium scan. This test uses a dye that can be viewed with a special camera. The dye will be injected into your veins and will collect around the diverticulum. This will allow your doctor to see the pouch in your intestines. The results of this test will confirm the presence of Meckel’s diverticulum.

Some patients may have active bleeding in their intestines as a result of Meckel’s diverticulum. This may make it difficult to view the diverticulum through the technetium scan. If this occurs, your doctor may need to order additional tests to confirm diagnosis. A colonoscopy or upper gastrointestinal endoscopy may be ordered. These tests use a camera to visualize the diverticulum.

How Is Meckel’s Diverticulum Treated?

Patients that have Meckel’s diverticulum but do not have any symptoms will not require treatment. Patients that experience symptoms of the condition may need to have surgery to have the diverticulum removed. Surgery typically includes removal of the diverticulum and repair of the intestines.

If the intestines have been damaged as a result of the diverticulum, the damaged part of the intestine may also need to be removed. Patients that experience blood loss as a result of Meckel’s diverticulum may also require iron therapy or blood transfusions to replace lost blood.

Surgery to correct Meckel’s diverticulum is typically associated with a low risk of complications. However, some complications can arise following surgery. In particular, scar tissue may develop following the removal of the diverticulum. This may cause a blockage of the intestines. Blockage of the intestines can be life threatening and may require additional surgery to remove the blockage.

What Is the Long-Term Outlook for Patients with Meckel’s Diverticulum?

The long-term outlook for patients that seek treatment for Meckel’s diverticulum is quite good. Surgical removal of the diverticulum typically results in normal intestinal function. Surgery also stops blood loss. Patients that have surgery for Meckel’s diverticulum can expect a full recovery.
