Congenital gastric outlet obstruction by pyloric membrane: prenatal and postnatal diagnosis and management.
Congenital gastric outlet obstruction is a rare condition representing only 1% of all gastrointestinal atresias. Prenatal diagnosis is uncommon and mostly confined to the third trimester of cases presenting a combination of polyhydramnios with dilated stomach. We report a case of congenital gastric outlet obstruction by pyloric membrane which was diagnosed prenatally in the third trimester by sonography and magnetic resonance imaging. The anomaly appeared to be isolated, thus a favorable outcome was expected. A baby girl weighing 3,430 g was delivered spontaneously at 36 weeks. Postnatal imaging methods confirmed the presence of a congenital gastric obstruction. 21 h after delivery, the baby underwent laparotomy, at which time a malrotation and pyloric membrane were found and resolved. The postoperative course was uneventful and the baby was discharged at the age of 18 days and remains well at controls.
