[Abnormalities of the stomach].

Malformations of the stomach are rare, their complications can be very dangerous in infancy. Clinical picture and diagnosis are discussed using 5 own cases (one 2-years-old girl with membraneous atresia, one 3-day-old boy with pylorus atresia, one 2-years-old boy with bleeding diverticulum of the stomach and a newborn with tubular hypoplasia (i.e. microgastria)). The treatment of these malformations is always surgical. Only cases of membraneous stenosis of the stomach may be treated endoscopically.
