Congenital Diarrhea: A Case Report on Challenges in Both Prenatal and Postnatal Diagnosis.

Prenatal recognition of congenital diarrhea and subsequent diagnosis can facilitate neonatal monitoring and prompt initiation of lifesaving postnatal treatment. We describe two cases with a congenital diarrheal disorder (CDD), highlighting the prenatal course and the diagnostic process. In cases of fetal dilated bowel loops, particularly with a characteristic honeycomb appearance, prenatal genetic testing for CDDs should be considered. After birth, distinguishing diarrhea from urine may be challenging in neonates with suspected congenital diarrhea. Therefore, urinary catheterization or a urine collection bag is recommended to ensure accurate assessment.
