Gastroschisis
Gastroschisis refers to an extra-abdominal herniation (evisceration) of fetal or neonatal bowel loops (and occasionally portions of the stomach and or liver) into the amniotic cavity through a para-umbilical anterior abdominal wall defect.
Epidemiology
The estimated incidence is around 1-6 per...

Omphalocele
Omphaloceles, also known as exomphalos (rare plural: exomphali), are congenital midline abdominal wall defects at the base of the umbilical cord insertion, with herniation of gut (or occasionally other structures) out of the fetal abdomen.
Epidemiology
The estimated occurrence can be up to 1:4...

Alpha-fetoprotein
Alpha-fetoprotein (AFP) is an important plasma protein synthesized by the yolk sac and fetal liver. In adults, its main utility is as a tumor marker, primarily for hepatocellular carcinoma or teratoma. Functionally it is the fetal homologue of albumin, i.e. it acts as a major carrier protein in ...

Ruptured omphalocele
Ruptured omphalocele occurs when there is rupture of the outer membrane of an omphalocele. When this happens the eviscerated fetal bowel looks free floating and distinction from gastroschisis becomes difficult. However, with a ruptured omphalocele, the abdominal defect generally tends to be larg...

In utero bowel perforation
In utero bowel perforation results in a chemical peritonitis (meconium peritonitis) from peritoneal leakage of sterile meconium.
It can result from many causes which include:
intestinal atresias:
jejuno-ileal atresia
ileal atresia
anal atresia
in utero intestinal ischemia
underlying gastr...

Twin embolization syndrome
Twin embolization syndrome (TES) is a rare complication of a monozygotic twin pregnancy following an in utero demise of the co-twin.
Pathology
It was traditionally thought to result from the passage of thromboplastic material into the circulation of the surviving twin which causes ischemic str...

11-13 week antenatal scan
11-13 week antenatal (nuchal translucency) scan is considered a routine investigation advised for fetal well-being as well as for early screening in pregnancy (see antenatal screening).
It includes multiple components and is highly dependent on the operator. Traditionally three factors are used...

Hemivertebra
Hemivertebra is a type of vertebral anomaly that results from a lack of formation of one half of a vertebral body. It is a common cause of congenital scoliosis.
Epidemiology
The estimated incidence is at ~0.3 per 1000 live births 2.
Associations
Recognized associations are many and include:...

Limb body wall complex
The limb-body wall complex (LBWC) is a rare variable group of congenital limb and body wall defects (involving mainly the chest and abdomen). They can include:
abdominoschisis: usually large and left-sided 4, and almost always present
thoracic wall defect / thoracoschisis
ectopia cordis
anom...
Article
Abdominoschisis
Abdominoschisis (plural: abdominoschises) refers to a split or defect in the abdominal wall. Some authors use the term synonymously with a gastroschisis. When the defect continues into the thoracic region it is termed a thoracoabdominoschisis. A large abdominoschisis is considered part of the li...
Article
Polyhydramnios
Polyhydramnios refers to a situation where the amniotic fluid volume is more than expected for gestational age.
It is generally defined as:
amniotic fluid index (AFI) >25 cm, though the cutoff in some centers is being reduced to 24 cm 14
largest fluid pocket depth (maximal vertical pocket) >8...

Physiological gut herniation
Physiological gut herniation is a natural phenomenon that occurs in early pregnancy. It usually occurs from around 6-8 weeks until 12-13 weeks in utero, after which the bowel returns to the abdominal cavity.
Physiology
It occurs as a result of the bowel (particularly ileum) growing faster tha...
