"A proximal part of the bowel is pulled into the distal lumen and propulsed forward as if it were a bolus of food. The prolapsing part of the bowel is described as the intussusceptum, while the distal segment of bowel receiving the intussusceptum is described as the intussuscipiens. As the mesentery is incorporated into the intussusception, venous return is compromised, resulting in oedema and further restriction of blood flow. Eventually, arterial supply to the bowel is interrupted, and ischaemia and necrosis ensue."

"In children, intussusception reduction can be achieved without recourse to surgery in most cases. Using a water-soluble medium or air introduced via a rectal catheter, retrograde pressure can be exerted to reduce the intussusception. If symptoms have been protracted, rectal blood is present; there are signs of peritonitis, or enema reduction is unsuccessful, then surgical intervention is usually required. Recurrence rates typically are reported as between 9-15% 20."

"While the classic triad of intermittent abdominal pain, vomiting, and right upper quadrant mass, plus occult or gross blood on rectal examination, has great positive predictive value for intussusception in children 1, these findings, taken together, are seen in less than 20% of intussusception cases 2. Approximately 15% (range 13-22%) of patients with intussusception do not even present with abdominal pain 3,4. Classic physical exam findings include an oblong palpable mass in the right upper quadrant, described as "sausage-like" with a paucity of palpable bowel in the right lower quadrant. Sometimes the parents will report the passing of red stool ("currant jelly" stool), which is stool mixed with blood and mucus and is a sign that bowel ischaemia has occurred."
"In the adult population, intussusception can occur essentially anywhere without a specific distribution pattern; in the vast majority of cases, a lead point lesion is present, and thus the location depends on that lesion 13."
