Insights
Meconium obstruction (MO) is common in extremely low birth weight infants (ELBWIs), often linked to prenatal factors. Medical treatment is effective for most MO cases, offering good feeding prognoses, while surgical intervention may lead to persistent gastrointestinal issues.
Area of Science:
- Neonatalogy
- Pediatric Surgery
- Gastroenterology
Background:
- Meconium obstruction (MO) in premature infants can lead to severe complications, including increased morbidity, mortality, and extended hospital stays.
- Prompt diagnosis and appropriate management are crucial for improving outcomes in affected infants.
Purpose of the Study:
- To determine the incidence and identify risk factors associated with meconium obstruction (MO) in extremely low birth weight infants (ELBWIs).
- To review and analyze the treatment outcomes for MO in this vulnerable population.
Main Methods:
- A retrospective analysis was conducted on 101 ELBWIs born between January 2007 and April 2009.
- Prenatal and neonatal factors were compared between infants with MO and a control group.
- Treatment outcomes, including response to medical and surgical interventions, were reviewed.
Main Results:
- Meconium obstruction (MO) was diagnosed in 22% of ELBWIs, with 82% having identifiable prenatal risk factors.
- Respiratory distress syndrome was significantly more common in the MO group (p = 0.001).
- Medical treatment successfully resolved MO in 77% of cases; the remaining underwent ileostomy, with some experiencing persistent gastrointestinal problems and delayed enteral feeding.
Conclusions:
- Meconium obstruction (MO) is a significant condition in ELBWIs, frequently associated with prenatal risk factors.
- Effective medical management offers good prognoses for subsequent feeding.
- Surgical intervention for MO may result in poorer long-term gastrointestinal outcomes compared to medical management.
Background:
Meconium obstruction (MO) of prematurity can result in increased morbidity or mortality and prolonged hospitalization if not diagnosed and treated appropriately.
Objectives:
The aims of our study were to identify the incidence and risk factors associated with MO and to review the treatment outcomes.
Methods:
A retrospective analysis was undertaken of 101 extremely low birth weight infants (ELBWIs) who were born between January 1, 2007, and April 1, 2009, at Seoul National University Hospital. Prenatal and neonatal factors were compared between the MO and control groups. The treatment outcomes were also reviewed.
Results:
Twenty-two (22%) patients were diagnosed as having MO. Eighteen of these patients (82%) had prenatal risk factors for MO. Respiratory distress syndrome was more prevalent in the MO group than in the control group (p = 0.001). Overall, 17 of the 22 patients (77%) were relieved with medical treatment and the rest underwent ileostomy. The times to full enteral feeding did not differ between the medically treated group and the control group. However, the surgically treated group required more time to achieve full enteral feeding, and some patients had persistent gastrointestinal problems.
Conclusion:
MO is not a rare condition in ELBWIs, and the majority of ELBWIs have prenatal risk factors. Medical management was effective, and medically manageable cases had good prognoses for subsequent feeding, whereas some surgically managed cases had persistent gastrointestinal problems.
