Intussusception is a condition where a segment of bowel ‘telescopes’ into the lumen of the
immediately adjacent part. A condition which is mostly idiopathic in children, less than 2 years
but associated with some pathology in older patients. Among the pathologies that initiate the
process of invagination, the most common ones are lymphomas, Meckel’s diverticulum, hamartomatous
polyps, haemangiomas and inverted appendiceal stumps. Most cases occur in otherwise
healthy male children and are commonly of ileo-colic type.
