Abdominal wall defects are a type of congenital defect that allows the stomach, the intestines, or other organs to protrude through an unusual opening that forms on the abdomen. [ 1 ] [ 2 ] During the development of the fetus, many unexpected changes occur inside the womb.
An umbilical hernia can be fixed in two different ways. The surgeon can opt to stitch the walls of the abdomen or place mesh over the opening and stitch it to the abdominal walls. The latter is of a stronger hold and is commonly used for larger defects in the abdominal wall.
Abdominal wall defects: thoracoschisis and/or abdominoschisis; Limb defects; As a component of the abdominal wall defect, the umbilical cord is shortened or absent with the fetus being directly attached to the placenta, a key feature in its prenatal diagnosis by ultrasound. [3] Several systems have been proposed to classify LBWC cases ...
An omphalocele or omphalocoele, also known as an exomphalos, is a rare abdominal wall defect. [1] Beginning at the 6th week of development, rapid elongation of the gut and increased liver size reduces intra abdominal space, which pushes intestinal loops out of the abdominal cavity.
The linea alba (Latin for: white line) is a strong fibrous midline structure [1] of the anterior abdominal wall [2] situated between the two recti abdominis muscles (one on either side). The umbilicus (navel) is a defect in the linea alba through which foetal umbilical vessels pass before birth. [1]
These defects are usually congenital and are not noticed until they slowly enlarge over an individual's life time and abdominal contents herniate through the hole creating either pain or a visible lump on the abdominal wall. If abdominal contents get incarcerated (or stuck) in the hole this can cause pain. If the abdominal contents become ...
an abdominal wall defect, lower sternal defect, congenital heart malformations, absence of the diaphragmatic pericardium, and an anterior diaphragmatic defect. [2] Abdominal wall defects in pentalogy of Cantrell occur above the umbilicus (supraumbilical) and in the midline, and have a wide range of presentations.
The first hypothesis does not explain why the mesoderm defect would occur in such a specific small area. The second hypothesis does not explain the low percentage of associated abnormality compared with omphalocele. The third hypothesis was criticized due to no vascular supplement of anterior abdominal wall by umbilical vein.
