Abstract
Lower gastrointestinal bleeding is an alarming symptom in pediatrics, especially in infancy.
However, it is commonly secondary to benign and self-limiting conditions, such as anal fissures,
infections, and allergies; more rarely it is caused by more serious disorders, such as necrotizing
enterocolitis, very early onset inflammatory bowel diseases, and vascular malformations.
The present review aims at summarizing the different clinical conditions presenting with rectal
bleeding in infancy and provides an evidence-based diagnostic work-up for the clinical management
of patients with this occurrence.
Keywords:
Rectal bleeding, infants, lower gastrointestinal bleeding, hematochezia, inflammatory bowel diseases, vascular malformations.
