Meconium peritonitis

Meconium peritonitis refers to rupture of the bowel prior to birth, resulting in fetal stool (meconium) escaping into the surrounding space (peritoneum) leading to inflammation (peritonitis).

Infants with cystic fibrosis are at increased risk for meconium peritonitis.

Twenty percent of infants born with meconium peritonitis will have vomiting and dilated bowels on x-rays which necessitates surgery.

[citation needed] Meconium peritonitis is sometimes diagnosed on prenatal ultrasound[1] where it appears as calcifications[2] within the peritoneum.

[citation needed] Meconium peritonitis was first described in 1838 by Carl von Rokitansky.
