Ileal atresia – malformation of the ileum, the lower part of the small intestine; Colon atresia – malformation of the colon; Malformations may also occur along multiple portions of the intestinal tract; for instance a malformation that occurs along or spans the length of the jejunum and the ileum is termed jejunoileal atresia.

The majority of cases are small intestinal atresia, while colonic atresias are uncommon. [14] There have been two main etiologies proposed for intestinal atresia: the first is a lack of re-vacuolization of the solid cord stage of intestinal development, and the second is a late intrauterine mesenteric vascular accident.
Duodenal atresia is the congenital absence or complete closure of a portion of the lumen of the duodenum. It causes increased levels of amniotic fluid during pregnancy (polyhydramnios) and intestinal obstruction in newborn babies. Newborns present with bilious or non-bilous vomiting (depending on where in the duodenum the obstruction is) within ...
Familial multiple intestinal atresia (FMIA) or familial intestinal polyatresia syndrome (FIPA) is an inherited disorder where atresia occurs at multiple locations throughout the small and large intestines. It presents at birth and the prognosis is very poor with almost all those diagnosed with this condition dying with one month.
Umbilical cord ulceration and intestinal atresia is a rare [1] congenital disease that leads to intestinal atresia, umbilical cord ulceration and severe intrauterine haemorrhage. Only 15 cases have so far been reported, [ 2 ] though newer studies are beginning to conclude that this disease has a higher incidence rate than has been previously ...
The intestinal atresia is of the "apple-peel" type, an uncommon type in which the remaining portion of the intestine is found twisted around its main artery, and this usually affects the jejunum. [2] [3] Often, much of the bowel is missing in this form of atresia. [9] There can sometimes also be intestinal malrotation. [2] [3] [8] [11]
Mutations in this gene are known to cause intestinal atresia, severe infantile or very early onset inflammatory bowel disease, extensive enteropathy, combined immunodeficiencies, thyroid dysfunction, alopecia, and lung disease.
A hepatoportoenterostomy or Kasai portoenterostomy is a surgical treatment performed on infants with Type IVb choledochal cyst and biliary atresia to allow for bile drainage. In these infants, the bile is not able to drain normally from the small bile ducts within the liver into the larger bile ducts that connect to the gall bladder and small ...
