Meconium peritonitis is a sterile and chemical peritonitis resulting from prenatal bowel perforation mainly associated with bowel obstruction. It occurs in 1 of 35,000 live births. The underlying bowel disease includes small bowel atresia,
volvulus,
internal bowel hernia, intussusception, congenital bands, vascular insufficiency, and unkown causes.
In recent years, meconium peritonitis has been frequently diagnosed in utero by means of prenatal sonography. Prenatal sonographic findings of meconium peritonitis include polyhydramnios, ascites, abdominal calcification, echogenic messes,
pseudocyst
and scrotal calcification.
Recently, Two cases of meconium peritonitis which are diagnosed in utero by means of ultrasonography are resolved in utero during serial follow-up examination.
We present these two cases with a brief review of literatures.
