A Meckel's diverticulum, a true congenital diverticulum, is a slight bulge in the small intestine present at birth and a vestigial remnant of the vitelline duct.It is the most common malformation of the gastrointestinal tract and is present in approximately 2% of the population, [1] with males more frequently experiencing symptoms.
Meckel's diverticulum, a persistent portion of the omphalomesenteric duct, is present in 2% of the population, [10] making it the most common congenital gastrointestinal malformation. [11] Histopathology of the gallbladder, showing a false diverticulum (larger than a Rokitansky–Aschoff sinus).
Their chemical composition is diverse, and rarely can a nidus be found. A differential diagnosis of an enterolith requires the enterolith, a normal gallbladder, and a diverticulum. [7] [8] An enterolith typically forms within a diverticulum. An enterolith formed in a Meckel's diverticulum sometimes is known as a
About two percent of fetuses exhibit a type of vitelline fistula characterized by persistence of the proximal part of the vitelline duct as a diverticulum protruding from the small intestine, Meckel's diverticulum, which is typically situated within two feet of the ileocecal junction and may be attached by a fibrous cord to the abdominal wall ...
A Littre hernia is a very rare type of hernia which occurs when a Meckel's diverticulum protrudes through a defect in the abdominal wall. [1] It is named after French physician Alexis de Littre. [2] This hernia may occur in a number of anatomical locations, typically in the inguinal region (50%), umbilicus (20%) or femoral canal (20%).
It is actively accumulated and secreted by the mucoid cells of the gastric mucosa, [18] and therefore, technetate(VII) radiolabeled with technetium-99m is injected into the body when looking for ectopic gastric tissue as is found in a Meckel's diverticulum with Meckel's scans. [19]
Intestinal malrotation is a congenital anomaly of rotation of the midgut.It occurs during the first trimester as the fetal gut undergoes a complex series of growth and development.
But in about two percent of cases its proximal part persists as a diverticulum from the small intestine, Meckel's diverticulum, which is situated about 60 cm proximal to the ileocecal valve, and may be attached by a fibrous cord to the abdominal wall at the navel.
