Long-term outcome after neonatal meconium obstruction

Area of Science:

• Pediatric Gastroenterology
• Neonatal Surgery
• Cystic Fibrosis Research

Background:

• Neonatal meconium ileus is a common initial manifestation of cystic fibrosis (CF).
• The long-term implications of meconium ileus in CF patients compared to those without meconium ileus or non-CF meconium obstruction are not well-defined.

Purpose of the Study:

• To compare the long-term outcomes of children with CF who presented with meconium ileus versus those with CF without meconium ileus.
• To evaluate the prognosis of neonates with meconium obstruction without CF (meconium plug syndrome).

Main Methods:

• A retrospective comparative study analyzed data from three groups: CF patients with meconium ileus (n=35), CF patients without meconium ileus (n=35), and infants with meconium plug syndrome (n=12).
• Outcomes assessed included pulmonary, gastrointestinal, nutritional, and functional status, along with surgical complications.

Main Results:

• CF patients with meconium ileus had a higher incidence of meconium ileus equivalent and significantly more long-term surgical complications (27%) compared to CF patients without meconium ileus.
• Complicated meconium ileus and surgical management involving resection or enterostomy were associated with increased surgical complication rates.
• Infants with meconium plug syndrome (no CF) demonstrated superior growth and functional status with fewer pulmonary and gastrointestinal issues.

Conclusions:

• Long-term outcomes for CF patients with and without meconium ileus are comparable, barring a slightly increased risk of meconium ileus equivalent and a notably higher rate of surgical complications in the meconium ileus group.
• Complicated meconium ileus and specific surgical interventions increase the risk of adverse surgical outcomes.
• Neonates with meconium obstruction but without CF have a favorable long-term prognosis, crucial information for family counseling.
