inguinal hernia
Protrusion of abdominal contents through the inguinal canal, more common in premature infants and males.
Full Definition
Inguinal hernia occurs when abdominal contents, typically intestine or omentum, protrude through the inguinal canal due to incomplete closure of the processus vaginalis during fetal development. The condition is significantly more common in males (8:1 ratio) and premature infants, with incidence as high as 30% in very low birth weight infants. Most pediatric inguinal hernias are indirect hernias. The main concern is incarceration, where the hernia becomes trapped and cannot be reduced, potentially leading to strangulation and bowel ischemia. Surgical repair (herniotomy) is typically recommended promptly after diagnosis in children.
