Customer Question

Hi - can you tell me what a meckel's test would be looking for?

A Nuclear Medicine Meckel's scan is performed to look for the presence of ectopic gastric mucosa in the large bowel. If this condition exists it can cause pain in the abdomen and blood in the stool.

Expert:  khagihara replied 1 year ago.

Because the gastric mucosa produces acid and irritate the large bowel.

Where would the pain be felt? Could an MRI see the same thing?
Expert:  khagihara replied 1 year ago.

Yes. MRI imaging studies obtained to evaluate abdominal pain may suggest a diagnosis of Meckel’s diverticulum, but these findings are usually nonspecific. In patients without immediate indications for abdominal exploration (eg, perforation), a suspicion for a bleeding Meckel’s diverticulum can be investigated with a Meckel's scan, which identifies the presence of ectopic gastric mucosa within the diverticulum.

Where would the pain be felt? And would there be any value in doing the test if an MRI was normal and there is no blood in the stool?
Expert:  khagihara replied 1 year ago.

Meckel's diverticulum is located in the distal ileum, usually within 60–100 cm (2 feet) of the ileocecal valve (lower right part). So the pain could be located in the lower middle part.

Expert:  khagihara replied 1 year ago.

Theoretically, the scan should identify only those diverticula that contain ectopic gastric mucosa, which occurs in less than 25 percent of cases. Meckel’s diverticula containing gastric mucosa can be detected with Meckel scan. Meckel’s diverticula lacking gastric mucosa will not be seen on a Meckel’s scan.
