Risk factors associated with postoperative recurrence and repeat surgery in Japanese patients with Crohn’s disease

Purpose To avoid frequent surgery in patients with Crohn’s disease, it is important to identify the risk factors for postoperative recurrence or repeat surgery. However, there have so far been few studies on this topic from Asian countries. In addition, the recent development of anti-tumor necrosis factor (TNF) therapy may have changed the risk factors. We aimed to identify the factors associated with postoperative recurrence and repeat surgery.
