Meckel's diverticulum
Information, Symptoms, Treatments and Resources
A Meckel's diverticulum is a common congenital (present from before birth) pouch on the wall of the small bowel. The diverticulum may contain stomach or pancreatic tissue.
A Meckel's diverticulum is a remnant of structures within the fetal digestive tract that were not fully reabsorbed before birth. Approximately 2% of the population has a Meckel's diverticulum, but only a few develop symptoms.
Symptoms include diverticulitis or bleeding in the intestine (see GI bleeding). Symptoms often occur during the first few years of life but may occur in adults as well.
- Visible blood in stool
- Occult (invisible) blood in the stool on multiple tests
- Iron deficiency anemia
Tests:
- Stool smear for occult blood (stool guaiac)
- Hematocrit
- Hemoglobin
- Technetium scan to demonstrate diverticulum
Surgery to remove the diverticulum is recommended if bleeding develops. In rare cases, the segment of small intestine which contains the diverticulum is surgically removed, and the ends of intestine sewn back together. Iron replacement may be needed to correct anemia. If bleeding is significant, blood transfusion may be necessary.
- Hemorrhage
- Perforation of the bowel at the diverticulum
- Peritonitis
- Intussusception with resultant obstruction
See your health care provider promptly if your child passes blood or bloody stool or complains repeatedly of abdominal discomfort.
