title: Extraordinary hyperbilirubinemia in a neonate with idiopathic hypertrophic pyloric stenosis.
abstract: This case describes an extraordinarily elevated total bilirubin level that reverted to normal 9 1/2 wk after Fredet-Ramstedt pyloromyotomy. Although the etiology of jaundice occurring in patients with IHPS remains uncertain, theories implicating inhibition of the glucuronyl transferase system have been proposed. Infants with IHPS have a documented hypergastrinemia. An hypothesis is offered, illustrated by this case, to explain the inhibition of the glucuronyl transferase system with resultant hyperbilirubinemia by the hypergastrinemia of idiopathic hypertrophic pyloric stenosis.
