An umbilical hernia is a health condition where the abdominal wall behind the navel is damaged. It may cause the navel to bulge outwards—the bulge consisting of abdominal fat from the greater omentum or occasionally parts of the small intestine. The bulge can often be pressed back through the hole in the abdominal wall, and may "pop out" when ...
A periumbilical mass is not always a Sister Mary Joseph nodule. Other conditions that can cause a palpable periumbilical mass include umbilical hernia, infection, and endometriosis. Medical imaging, such as abdominal ultrasound, may be used to distinguish a Sister Mary Joseph nodule from another kind of mass. [2]
It is possible for the bulge associated with a hernia to come and go, but the defect in the tissue will persist. Symptoms may or may not be present in some inguinal hernias. In the case of reducible hernias, a bulge in the groin or in another abdominal area can often be seen and felt. When standing, such a bulge becomes more obvious.
A paraumbilical (or umbilical) hernia is a hole in the connective tissue of the abdominal wall in the midline with close approximation to the umbilicus. If the hole is large enough there can be protrusion of the abdominal contents, including omental fat and/or bowel .
An epigastric hernia is a type of hernia that causes fat to push through a weakened area in the walls of the abdomen. It may develop in the epigastrium (upper, central part of the abdomen ). Epigastric hernias are more common in adults and usually appear above the umbilical region of the abdomen.
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.
Outies are sometimes mistaken for umbilical hernias; however, they are a completely different shape with no health concern, unlike an umbilical hernia. The navel (specifically abdominal wall) would be considered an umbilical hernia if the protrusion were 5 centimeters or more. The diameter of an umbilical hernia is usually 1/2-inch or more. [9]
Internal hernias occur when there is protrusion of an internal organ into a retroperitoneal fossa or a foramen (congenital or acquired) in the abdominal cavity. If a loop of bowel passes through the mesenteric defect, that loop is at risk for incarceration , strangulation , or for becoming the lead point of a small bowel obstruction . [ 1 ]
