Possible local complications of Crohn's disease include:

  • intestinal obstruction
  • haemorrhage
  • perforation with abscess
  • stricture formation; common
  • perianal abscess fistula
  • fistulae to the bowel, bladder, vagina
  • increased risk of malignancy but less than that of ulcerative colitis

Notes:

  • abdominal or pelvic abscesses occur in 10–30% of patients with Crohn's disease (1)
  • pyogenic hepatic abscess is a recognized rare late complication of Crohn’s disease that occurs at a higher incidence than the general population
    • hepatic abscesses commonly present as multiple lesions occurring in a younger patient (<40 yrs old) with Crohn’s disease and drainage yields a single organism, typically streptococci (2)
