Gastrointestinal involvement in Behçet's disease (GIBD) and Crohn's disease (CD) are inflammatory diseases sharing a considerable number of similarities. However, different from CD, the operative and postoperative management of GIBD remains largely empirical because of the lack of comprehensive treatment guidelines.
To compare surgical patients with GIBD and those with CD in a medical center and identify notable clinical features and effective postoperative treatment for surgical patients with GIBD.
We searched patients diagnosed with CD and GIBD who underwent operations for gastrointestinal complications from 2009 to 2015 at West China Hospital of Sichuan University. A total of 10 surgical patients with GIBD and 106 surgical patients with CD were recruited. Information including demographic data, medication, and operative and postoperative parameters were collected and analyzed. As the incidence of surgical GIBD is low, their detailed medical records were reviewed and compared to previous studies. Moreover, the prognoses of CD and GIBD were evaluated respectively between groups treated with biological and non-biological agents.
Indication for first surgery was often acute intestinal perforation for GIBD patients (7/10 
Patients suffering GIBD require surgery mostly under emergency situations, which may be more susceptible to recurrence and reoperation and need more aggressive postoperative treatment than patients with CD.
