What condition is characterized by current jelly stools in children?

The condition characterized by currant jelly stools in children is intussusception. Intussusception occurs when a part of the intestine telescopes into an adjacent segment, causing obstruction. This condition can lead to ischemia and may result in blood and mucus being present in the stool, producing a classic appearance described as "currant jelly."

In children, this presentation is particularly significant as it often indicates a serious medical issue requiring prompt evaluation and treatment. Intussusception is commonly seen in infants and toddlers, and it can be associated with symptoms such as abdominal pain, vomiting, and a palpable abdominal mass. The currant jelly stools result from the mixing of blood and mucus, which is why this symptom is so distinctive and indicative of the condition.
