title: Response rates to medical treatments and long-term clinical outcomes of nonsurgical patients with intestinal Behçet disease.
abstract: BACKGROUND
  The aims of this study were to evaluate the efficacy of medical treatments and to identify factors to predict clinical outcome of intestinal Behçet disease (BD) during medical treatment.
  
  
  METHODS
  We performed a retrospective review of the medical records of 93 patients who were diagnosed and medically treated with intestinal BD at Severance Hospital, Seoul, Korea from 1992 to 2007. A therapeutic response was evaluated 8 weeks after the initiation of medical treatment, and cumulative recurrence and surgery rates were also assessed during long-term follow-up.
  
  
  RESULTS
  The initial remission rate at 8 weeks after treatment was 66.7%. During the follow-up period, cumulative recurrence rates for intestinal BD were 24.9% at 2 years and 43.0% at 5 years. The recurrence rate was significantly higher in patients with apparent gastrointestinal symptoms at their initial presentation, volcano-type and deep intestinal ulcers, and those who failed to achieve complete remission during the initial treatment. Cumulative rates for surgery were 6.7% at 2 years and 15.1% at 5 years. The typical type of ulcers was the only predictive factor for the likelihood of surgery.
  
  
  CONCLUSIONS
  Our study demonstrates that a considerable number of patients experience disease relapse during follow-up despite a high-remission rate after medical treatment for intestinal BD. Careful observation and intensive treatment should be carried out, especially in patients without complete remission after initial treatment, with deep and volcano-shaped ulcers, or with apparent gastrointestinal symptoms at the time of diagnosis.
