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 ...
Hernia repair is a surgical operation for the correction of a hernia—a bulging of internal organs or tissues through the wall that contains it. It can be of two different types: herniorrhaphy ; or hernioplasty . [ 1 ]
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 .
By far the most common hernias (up to 75% of all abdominal hernias) are inguinal hernias, which are further divided into the more common indirect inguinal hernia (2/3, depicted here), in which the inguinal canal is entered via a congenital weakness at its entrance (the internal inguinal ring), and the direct inguinal hernia type (1/3), where ...
In the disease the muscle undergoes normal differentiation but fails to expand ventro-medially and narrow the umbilical ring which causes the natural umbilical hernia that occurs at 6 weeks of gestation to remain external to the body. [14] The location of the folding defect in the embryo determines the ultimate position of the exomphalos.
In some cases of defect either the umbilical opening is too oversized or has developed improperly which allows the organs to remain outside or to squeeze through the abdominal wall. [1] There are two main types of abdominal wall defects that result due to the changes during development. They are omphalocele and gastroschisis. Gastroschisis ...
