Infolding; Introversion; Invagination
Intussusception occurs when a part of the intestine (intussusceptum) telescopes or is invaginated into the distal segment (intussuscipiens) and drags the mesentery with it. It was first described in 1674 by Barbette and was first treated successfully by surgery in 1831. This condition represents one of the four major causes of obstruction: herniation, adhesion, volvulus, and intussusception. Usually, in children, invagination is idiopathic, but there are a lot of points of traction that can determine invagination of the bowel segments like tumors or different intraluminal masses. In adults, intussusception in the small bowel generally has as a lead point a benign or inflammatory lesion, while that occurring in the large bowel is more likely of malignant etiology.
Alteration of intestinal motility (hyperperistalsis; irregular, retrograde, or reduced peristalsis) is considered to be responsible for intussusception in some cases....
