'''Intussusception''' is the invagination of one portion of the gastrointestinal tract into the lumen of the adjacent portion.  The intussusceptum is the invaginated segment and the intussuscipien is the enveloping segment. A normograde intussusception is most common, but retrograde intussusception has also been reported.

Intussusceptions can be classified according to their location in the gastrointestinal tract. They usually occur in regions where there is a significant change in lumen diameter, such as ileocolic and gastroesphageal junctions. Ileocolic intussusceptions are most common, they frequently protrude from the rectum and must be distinguished from a rectal prolapse. In the case of an intussusception, it is possible to pass a probe next to the anus, but not in a [[Rectal Prolapse|rectal prolapse]].

===Ultrasound===

Abdominal ultrasound will reveal a cylindrical mass with layering of the intestinal wall. The intestines may also be hypomotile, with distension proximal to the obstruction.

Colonoscopy can identify ileocolic or caecocolic intussusception. Oesopgagoscopy can reveal a gastroesophageal intussusception, a soft tissue mass is visible in the lumen of the oesophagus.
