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.
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
On this site of attachment, sometimes a pathological Meckel's diverticulum may be present. A mnemonic used to recall details of a Meckel's diverticulum is as follows: "2 inches long, within 2 feet of ileocecal valve , 2 times as common in males than females, 2% of population, 2% symptomatic, 2 types of ectopic tissue: gastric and pancreatic".
A jejunal diverticulum is a congenital lesion and may be a source of bacterial overgrowth. It may also perforate or result in abscesses. A Killian-Jamieson diverticulum is very similar to a pharyngeal esophageal diverticulum, differing in the fact that the pouching is between the oblique and transverse fibers of the cricopharyngeus muscle.

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%).
This is a list of publishers of academic journals by their submission policies regarding the use of preprints prior to publication (example list). Publishers' policies on self-archiving (including of preprint versions) can also be found at SHERPA/RoMEO.
In complicated diverticulitis, an inflamed diverticulum can rupture, allowing bacteria to subsequently infect externally from the colon. If the infection spreads to the lining of the abdominal cavity (the peritoneum), peritonitis results. Sometimes, inflamed diverticula can cause narrowing of the bowel, leading to an obstruction.
