PY - 2011 T2 - Rudolph's Pediatrics, 22e AB - Intussusception occurs when one portion of the small bowel (intussusceptum) peristalses into the lumen of a downstream portion (intussuscipiens), much like a collapsing telescope. Once this prolapse has occurred, lymphatic and venous drainage of the intussusceptum is impaired. This results in edema, strangulation, ischemia, and ultimately necrosis if the intussusception persists. Additionally, the lumen of the intussuscepted portion of bowel collapses, causing intestinal obstruction.
