Meckel’s Diverticulum • remnant of the embryonic yolk sac • Embyonal stage: omphalomesenteric duct connects the yolk sac to the gut, nutrition • 5th and 7th wk AOG: duct separates from the intestine • Yolk sac + lining epith similar to stomach • Partial or complete failure of involution of the omphalomesenteric duct results in various residual structures.
Frequency • Occurs in 2–3% of all infants • a 3–6 cm outpouching of the ileum along the antimesenteric border 50–75 cm from the ileocecal valve • 1st 2 years of life, 2.5yo
Manifestations • Intermittent painless rectal bleeding • Stool: brick colored or currant jelly colored. • Bleeding: self-limited, contraction of the splanchnic vessels • r/o acute appendicitis • Diverticulitis can lead to perforation and peritonitis
Diagnosis • Meckel radionuclide scan: IV infusion of technetium-99m pertechnetate: mucus secreting ectopic gastric mucosa : visualization of the Meckel diverticulum • sensitivity enhanced scan : 85% • specificity : 95%. • Other methods of detection: abdominal ultrasound, superior mesenteric angiography, abdominal CT scan, and exploratory laparoscopy.
