This refers to a condition in children where one part of the intestine protrudes into an adjacent part of the intestine.
This results in an obstruction or blockage and prevents food or fluid passing through the intestine as it should. It is more common in otherwise healthy children between the ages of 6 months and 3 years but may occur before or after this age group. If left untreated it can interfere with blood flow to the intestines and may even result in a perforation or hole in the intestines.
Children typically present with colicky abdominal pain and red bloody mucoid stool. This may give the stools the appearance of currant jelly or strawberry jam.
Treatment involves pushing the intestines back into the correct positon using either an air enema or surgery.
