What is Meconium Ileus?

Meconium Ileus is a bowel obstruction in newborns caused by thick, sticky meconium (the baby’s first stool) blocking the small intestine, typically the ileum. It is often the first sign of cystic fibrosis (CF) and requires prompt treatment to avoid complications like bowel perforation or infection.

Causes and Risk Factors

  • Cystic Fibrosis (present in up to 90% of cases)

  • Abnormal meconium composition (very thick and dehydrated)

  • Underdeveloped intestinal motility

  • Family history of genetic disorders

Symptoms of Meconium Ileus

  • No passage of meconium within the first 24–48 hours after birth

  • Abdominal distension (swollen belly)

  • Vomiting, often greenish (bilious)

  • Poor feeding

  • Dehydration and lethargy

Diagnosis at Little Light Clinic

  • Abdominal X-rays (showing dilated bowel loops)

  • Contrast Enema (helps identify the blockage)

  • Genetic testing if cystic fibrosis is suspected

  • Ultrasound for prenatal diagnosis in some cases

Treatment Options

Non-Surgical (Medical) Management:

  • In uncomplicated cases, a contrast enema may help flush the meconium and relieve the obstruction.

Surgical Intervention:

  • If non-surgical treatment fails or there are complications (e.g., perforation, volvulus), surgery is necessary.

  • The blocked segment is removed, and a temporary stoma may be created, followed by a second-stage surgery for bowel reconnection.
