[Meconium peritonitis: intrauterine follow-up--postnatal outcome].

In nine patients with meconium peritonitis prenatal ultrasonographic findings were correlated with the clinical course and outcome. Ultrasound findings included polyhydramnion (n = 4), ascites (n = 4), disseminated (n = 3) and solitary echogenic areas (n = 1), echopoor cystic areas (n = 3) and echogenic-echopoor solitary areas (n = 1). Intra-abdominal calcifications were found in five patients before delivery. Eight neonates survived and were subsequently followed up, one fetus died in utero. Four of the eight survivors required surgery, namely for meconium ileus (n = 1), perforation secondary to intestinal volvulus (n = 2) and inguinal hernia associated with prenatal rubella infection (n = 1). Three patients were healthy, one patient required drainage of pleural effusion and respirator therapy but recovered without further problems. Cystic fibrosis was diagnosed in the patient with meconium ileus. Postnatal outcome could not be predicted from the prenatal sonographic findings.
