|A.||It is usually found in the jejunum on the antimesenteric border & is approximately 5 cm long|
It is 60 cm away from the ileocecal valve
It is seen in 2% people, usually presenting a patient over 2 years of age
It involves 2 two layers of the intestinal wall only
Answer B) It is 60 cm away from the ileocecal valve
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 omphalomesenteric duct (also called the vitelline duct or yolk stalk).
It is the most common malformation of the gastrointestinal tract and is present in approximately 2% of the population, with males more frequently experiencing symptoms.
Signs & Symptoms
The majority of people with a Meckel’s diverticulum are asymptomatic. An asymptomatic Meckel’s diverticulum is called a silent Meckel’s diverticulum.
If symptoms do occur, they typically appear before the age of two years.
- The most common presenting symptom is painless rectal bleeding such as melaena-like black offensive stools,followed by intestinal obstruction, volvulus and intussusception.
Meckel’s diverticulum is located in the distal ileum, usually within 60–100 cm (2 feet) of the ileocecal valve.
This blind segment or small pouch is about 3–6 cm (2 inch) long and may have a greater lumen diameter than that of the ileum.
It runs antimesenterically and has its own blood supply.
It is a remnant of the connection from the yolk sac to the small intestine present during embryonic development.
It is a true diverticulum, consisting of all 3 layers of the bowel wall which are mucosa, submucosa and muscularis propria.
