Meckel's Diverticulum (Displaced) (Hypertrophic): Causes, Symptoms, and Diagnosis

Meckel's diverticulum is a common gastrointestinal condition that affects about 2% of the population. It is a small pouch or sac that forms in the wall of the lower part of the small intestine, known as the ileum. In some cases, the diverticulum may become displaced, meaning it is not located in its usual position.

While the exact cause of Meckel's diverticulum is still unknown, it is believed to occur during fetal development. This condition arises when a small portion of the tissue connecting the intestines, known as the omphalomesenteric duct, fails to disappear as it should. As a result, the diverticulum forms and may become hypertrophic, meaning it grows larger than normal.

Meckel's diverticulum is often asymptomatic and may go undiagnosed. However, when symptoms are present, they can vary from person to person. Common symptoms include abdominal pain, which may be severe or intermittent, and may be accompanied by bleeding from the rectum. Other possible symptoms include nausea, vomiting, and a change in bowel habits.

Diagnosing Meckel's diverticulum can be challenging due to its nonspecific symptoms. However, certain diagnostic tests can help identify the condition. Imaging tests such as computed tomography (CT) scans or magnetic resonance imaging (MRI) scans can visualize the diverticulum and any complications that may have occurred. Additionally, a technetium-99m pertechnetate scan, also known as a Meckel's scan, can detect the presence of gastric tissue within the diverticulum.

1. Causes:

The exact cause of Meckel's diverticulum is unknown. However, it is believed to be a congenital condition that occurs during fetal development. It arises when the omphalomesenteric duct does not completely disappear, leading to the formation of the diverticulum.

2. Symptoms:

Meckel's diverticulum may not cause any symptoms in some individuals. However, when symptoms are present, they can include abdominal pain, rectal bleeding, nausea, vomiting, and changes in bowel habits.

3. Diagnosis:

Diagnosing Meckel's diverticulum can be challenging due to its nonspecific symptoms. Imaging tests such as CT scans, MRI scans, and Meckel's scans can help visualize the diverticulum and confirm the diagnosis.

It is important to note that Meckel's diverticulum does not always require treatment if it is asymptomatic.
