Study Notes
Gastrointestinal Embryology
- Atresia: Blockage of a portion of the digestive tube caused by failure to recanalize.
- Congenital Omphalocele: Failure of the intestines to return to the abdominal cavity after physiological herniation, associated with genetic abnormalities (~50%).
- Gastroschisis: A defect in the anterior abdominal wall (usually on the right), exposing abdominal viscera to the amniotic fluid. Risked for volvulus (intestinal twisting) exposure.
- Meckel's Diverticulum: Incomplete degeneration of the vitelline duct (a portion of the original embryonic gut tube). Normally asymptomatic; about 2 inches long (2 feet from ileocecal junction), in 2% of the population. Can cause symptoms if inflamed or obstructs.
- Accessory Pancreatic Tissue: Misplaced pancreatic tissue along the gut tube. Commonly found with Meckel's Diverticulum; usually asymptomatic.
- Annular Pancreas: A rare condition where the ventral pancreatic bud forms a ring around the descending duodenum, potentially causing inflammation (pancreatitis) and stenosis (narrowing) of the duodenum.
