While a human fetus is developing, the vitelline duct connects the intestines to the umbilical cord. When this duct does not properly close, the small intestine walls create a pouch or a condition called Meckel’s diverticulum.
Most people with Meckel’s diverticulum do not experience symptoms. However, certain individuals may be symptomatic and experience complications that may need surgery to remove the small intestinal pouch.
Keep reading to learn more about what causes Meckel’s diverticulum, symptoms, diagnosis, treatment options, and general outlook.

Sex and gender exist on spectrums. This article will use the terms “male,” “female,” or both to refer to sex assigned at birth. Click here to learn more.
Meckel’s diverticulum is
During human development, the vitelline duct communicates between the gut and the yolk sac. It typically disintegrates between the 5th and 9th weeks of pregnancy.
In some cases, the vitelline duct does not completely disintegrate, which causes Meckel’s diverticulum. The presence of a diverticulum in the small intestine is when the wall pushes out and creates a sac-like pouch.

Approximately 2% of the population develops Meckel’s diverticulum. Most of these cases are asymptomatic, or do not cause noticeable symptoms or complications.
The possible complications may vary across children and adults.
Incidence in children
Researchers in this study noted that male and female infants had an equal incidence rate, but males were more likely to develop complications. They also noted that the number of complications decreases among older children.
Parents and caregivers should immediately take children to a doctor if they show bowel obstruction signs. Rapid treatment is necessary to address this condition.
Incidence in adults
Doctors rarely diagnose adults with Meckel’s diverticulum. Most adults with this condition experience few, if any, symptoms.
Asymptomatic adults may discover they have Meckel’s diverticulum during an imaging test for another condition. In these cases, treatment may not be necessary or advisable.
The symptoms of diverticulitis may mimic those of appendicitis, but diagnostic tests can help doctors make a correct diagnosis.
Infants and children who show signs of Meckel’s diverticulum will undergo certain tests before diagnosis.
The diagnosis of bleeding Meckel’s diverticulum can be challenging.
A technetium-99m pertechnetate scan (Meckel’s scan) is
During these tests, an imaging technician will place a camera over the lower right area of the abdomen. The camera will take continuous images for approximately 30 minutes. This test is Meckel’s diverticulum scintigraphy and is up to 90% accurate at diagnosing this condition.
Another way to diagnose an adult is through double-balloon enteroscopy (DBE).
DBE is accurate at diagnosing Meckel’s diverticulum. However, a medical professional may suggest exploratory surgery if the source of GI bleeding is still undetected and a person is losing a lot of blood.
The treatment options may differ for children and adults.
Children with Meckel’s diverticulum
Surgical treatment also involves the removal of the diverticula. Most children who undergo this surgery recover fully and do not experience serious complications.
The treatment process is slightly
However, adults often find out they have Meckel’s diverticulum during another GI procedure or surgery. Surgery might not be the best choice when doctors discover this condition incidentally, and people do not show any symptoms.
Depending on the case, surgery in adults may cause them to
Adults with Meckel’s diverticulum should work with a doctor to determine what treatment option is right for them.
In most cases, people with Meckel’s diverticulum do not experience any symptoms. Adults with this condition may never even know they have it.
Children are at a
Individuals who undergo surgical treatment may be at risk for infection or intestinal blockage from scar tissue. Regular follow-up appointments after surgery are necessary to mitigate these and other risks.
Meckel’s diverticulum is a congenital condition that affects the small intestine. Symptoms from Meckel’s diverticulum are more common in children but can be present in some adults.
Treatment for this condition may include surgery, depending on whether or not symptoms are present. A doctor can consider an individual’s health and recommend the best treatment for them.
Most cases do not cause any symptoms. However, if complications arise from Meckel’s diverticulum, with the right care and follow-up examinations, individuals rarely experience long-term complications.
