Meconium peritonitis: a benign course in a premature infant

Area of Science:

• Neonatal Medicine
• Pediatric Surgery
• Gastroenterology

Background:

• Meconium peritonitis, a serious neonatal condition, often results from bowel perforation in utero.
• Intraperitoneal calcifications are a common radiographic sign associated with meconium peritonitis.
• Differential diagnosis includes congenital intestinal obstruction and cystic fibrosis, which require specific genetic or clinical evaluations.

Observation:

• A premature infant presented with clinical and radiographic evidence of meconium peritonitis and diffuse intraperitoneal calcifications.
• The infant's clinical course was notably mild, without signs of severe distress or systemic compromise.
• Postnatal investigations, including imaging and clinical assessment, were performed to evaluate for underlying causes.

Findings:

• The infant demonstrated a complete and uncomplicated recovery following conservative management.
• Diagnostic workup excluded any evidence of congenital intestinal obstruction, such as malrotation or atresia.
• Genetic and clinical assessments did not support a diagnosis of cystic fibrosis in this patient.

Implications:

• This case underscores that meconium peritonitis, even with calcifications, can have a benign course in premature infants.
• It highlights the importance of considering less severe etiologies and the possibility of spontaneous resolution.
• Further research may elucidate factors predicting milder presentations and outcomes in neonatal meconium peritonitis.
