Meckel diverticulum

ileal diverticulum

a remnant of the proximal part of the yolk stalk within the embryo that arises as a fingerlike diverticulum, 3-6 cm long, from the antimesenteric border of the ileum between 40 and 50 cm from the ileocecal junction; it may be attached to the umbilicus. If its mucosa includes gastric tissue, peptic ulceration and bleeding may result. Synonym(s): Meckel diverticulum

Mec·kel di·ver·ti·cu·lum

(mek'el dī'vĕr-tik'yū-lŭm) The remains of the yolk stalk of the embryo, which, when persisting abnormally as a blind sac or pouch in the adult, is located on the ileum a short distance above the cecum; it may be attached to the umbilicus and, if the lining includes gastric mucosa, peptic ulceration and bleeding can occur.
Synonym(s): ileal diverticulum.
