title: [The changes in incidence of Crohn's disease and intestinal tuberculosis in Korea].
abstract: OBJECTIVE
  The incidence of Crohn's disease (CD) has been steadily increasing in Korea due to westernized life style and widely used imaging studies such as colonoscopy. There were few studies about the status of longterm trend of CD and intestinal tuberculosis (IT). Therefore, we aimed to evaluate the trend of CD and IT in Korea.
  
  
  METHODS
  We retrospectively reviewed the medical records of newly diagnosed 65 patients with CD and 54 patients with IT at Chonnam National University Hospital between January 1998 and August 2007.
  
  
  RESULTS
  Between 1998 and 2002, 16 and 40 patients were newly diagnosed as having CD and IT respectively, but between 2003 and 2007, 39 and 14 patients were newly diagnosed as having CD and IT respectively. CD patients (28.2+/-15.2 years) were younger than IT (46.2+/-18.5 years) (p=0.001). The male to female ratio of CD and IT were 2:1 and 1.1:1, respectively. The most common symptom of CD and IT was abdominal pain. Longitudinal ulceration, hyperemia, luminal narrowing, pseudopolyp, and cobble stone appearance were more common in CD than in IT (p<0.05).
  
  
  CONCLUSIONS
  While the incidence of CD has increased, the incidence of IT has fallen over the last decade.
