Meckel's diverticulum

A Meckel diverticulum is a pouch on the wall of the lower part of the small intestine that is present at birth (congenital). The diverticulum may contain tissue similar to that of the stomach or pancreas.

Meckel diverticulum

Meckel diverticulum is one of the most common congenital abnormalities. It occurs when the connection between the intestine and the umbilical cord doesn't completely close off during fetal development. This results in a small outpouching of the small intestine, know as a Meckel diverticulum. In most cases, Meckel diverticula do not cause any problems. In a small number of patients however, these diverticula can become infected (diverticulitis) cause an obstruction of the intestine, or cause bleeding from the intestine. The most common symptom of Meckel diverticulitis is painless bleeding from the rectum. The stools may contain fresh blood or may look black and tarry.

Digestive system

The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

Digestive system organs

The digestive system organs in the abdominal cavity include the liver, gallbladder, stomach, small intestine and large intestine.
