Risk factors and surgical outcomes in pediatric patients with congenital heart disease and ischemic colitis

Area of Science:

• Pediatric Cardiology
• Neonatal Surgery
• Gastroenterology

Background:

• Congenital heart defects (CHD) are associated with an increased risk of ischemic colitis (IC), particularly in neonates.
• Previous studies highlight a higher incidence of IC in very low birth weight neonates with CHD.

Purpose of the Study:

• To investigate the risk factors associated with the development of ischemic colitis (IC) in pediatric patients with congenital heart defects (CHD).
• To evaluate the surgical outcomes and mortality rates in pediatric patients with CHD who develop IC.

Main Methods:

• Retrospective analysis comparing patients with IC and CHD to a control group with CHD only.
• Key variables analyzed included gestational age, birth weight, prematurity, APGAR scores, cardiac and surgical characteristics, and mortality.
• Surgical outcomes such as bowel resection and stoma procedures were assessed.

Main Results:

• The IC-CHD group presented with significantly lower gestational ages and birth weights, and higher rates of prematurity and multiple pregnancies.
• Patients with IC-CHD showed lower APGAR scores, increased ECMO use, and shorter cardiopulmonary bypass times.
• Higher rates of bowel resection and significantly increased mortality were observed in the IC-CHD group, with elevated Aristotle scores correlating with poorer outcomes.

Conclusions:

• Gestational age, birth weight, and initial health status are critical predictors of IC risk and surgical outcomes in pediatric CHD patients.
• The IC-CHD group requires vigilant monitoring and tailored interventions due to significantly higher mortality and complex surgical demands.
• Future research should focus on developing targeted therapeutic strategies and adjusting for confounding factors.
