PY - 2016 T2 - Anesthesiology Core Review: Part Two Advanced Exam AB - Pyloric stenosis, occurring in approximately 1 out of 600 live births, is one of the most common gastrointestinal abnormalities of the newborn. It usually manifests within the first few weeks of life and affects males three to four times more often than females, and firstborn males are more likely to be affected than their siblings. Pyloric stenosis consists of hypertrophied circular and longitudinal fibers of the muscularis propria of the pylorus that results in gastric outlet obstruction. It may occur in association with Turner syndrome, Edward’s syndrome (trisomy 18), or esophageal atresia.
