Intussusception is a serious medical condition found usually in infants where part of the intestines telescopes into an adjacent segment of the intestines. Patients usually present with bilious emesis, currant-jelly stools, and abdominal distention. The area of affected intestines is generally palpable (right hypochondrium). Malrotation is a congenital disorder where the midgut fails to rotate correctly during development; it is generally diagnosed in utero or during the immediate neonatal period. Pyloric stenosis is characterized by an almond-shaped knot in the upper right quadrant of the abdomen and projectile vomiting. Necrotizing enterocolitis is a multifactorial condition most commonly found in premature infants that is generally associated with a period of ischemia to the gut.
