Meckel's diverticulum results from incomplete obliterations of the
vitelline duct at the ileum and appears as a finger-like protrusion of intestine measuring 1-5 cm on the antimesenteric surface of the middle ileum.
The band was identified as the obliterated
vitelline duct. The diverticulum was seen about 20 cm proximal to the ileocecal valve, arising from the anti-mesenteric border of the distal ileum.
Meckel's diverticulum is a remnant of omphalomesenteric or
vitelline duct [7].
Meckel's diverticlulum is an intestinal diverticulum that results from the failure of the
Vitelline duct to obliterate during the fifth week of fetal development (Turgeon & Barnett, 1990).
Meckel's diverticulum is a remnant of the
vitelline duct that is usually located 45 to 60 cm proximal to the ileocecal valve on the antimesenteric border of the ileum.1 It is the most common congenital anomaly of the small intestine, occurring in 2% of the population.
As the
vitelline duct is made up of pluripotent cell lining, Meckel's diverticulum may harbour abnormal tissues, containing embryonic remnants of other tissue types.
[1] It is an incomplete closure of the omphalomesenteric or
vitelline duct and maybe present in forms ranging from an unseen bump to a long projection in communication with the umbilicus via a persistent fibrous cord.
