Intussusception

Question 1

intussusception

Answer 1

one part of the intestine pushes into an adjacent section of the intestine

Question 2

common area for intussusception to occur

Answer 2

ileocecal valve

Question 3

why is ileocecal valve common area

Answer 3

build up of pressure forces the small bowel to invaginate the large bowel

Question 4

patho

Answer 4

obstruction at site of invagination (ex. tumor) –> inflm –> inc production of exudate, hyperemia –> ischemia
- bowel obstr causes inc intraluminal pressure and pushes against the wall and constricts the vessels in the bowel wall –> ischemia –> infarction

Question 5

cmplx

Answer 5

• infarction

- perforation –> peritonitis

Question 6

how does peritonitis occur

Answer 6

necrosis of tissue can result in perforation of that area of the bowel and the bacteria within the intestine can infect the necrotic tissue –> bacterial peritonitis

Question 7

tx

Answer 7

hydrostatic reduction

Question 8

hydrostatic reduction

Answer 8

water-soluble contrast medium that uses air and water pressure to push back the invaginated area
