    • spreads inward and outward
    • involves mucosa and serosa
    • Transmural
  3. what are "skip lesions"
    the distribution os inflammation segments seperated by normal tissue
  4. as the inflammation begins what type of lesion develops in the mucosal layer
    shallow ulcers
  5. what is meant by the phrase "cobblestone appearence"
    shallow ulcers combine and form fissures to seperate them
  6. describe the progressive inflammatory changes that occur in the intestinal wall
    • inflammation becomes transmural
    • intestine forms rubber hose wall
    • lumen narrows forming string sign
  7. what types of digestive impairments would be caused by Croh's disease
    digestion and absorption
  8. What is the etiology of Crohn's disease
    • idiopathic
    • age 20-40
    • family history
    • gender
    • infection
    • allergies
    • lymphatic obstructions
  9. what are the inital symptoms

    • abdominal pain-RLQ
    • appendicitis
  14. what tests are used to diagnosis Crohn's

    • colonoscopy and sigmoidoscopy for biopsy
  15. what are possible complications of Crohn's
    • adhesions
    • absecesses
    • fistulas(abnormal passage ways)
    • fissures
  16. where would fistulas develop and what organs would be involved
    • between 2 loops of intestine
    • skin & intestine
    • bladder & intestine
  17. what is the treatment for Crohn's
