| Outline of Final Research Achievements |
The prevention of postoperative recurrence is a critical issue in surgery for Crohn’s disease (CD). The aim of this study was to investigate the efficacy and safety of planned postoperative anti-TNF-α therapy after surgery in Japanese patients with CD. Twenty-six patients with CD undergoing surgical resection were enrolled. All patients received postoperative anti-TNF-α, adalimumab (ADA), therapy within 2 weeks after surgery. The primary endpoint of this study was the incidence of endoscopic recurrence. Endoscopic recurrence was observed in 31% of patients 1 year after surgery. Univariate analyses show that preoperative ADA therapy was significantly associated with endoscopic recurrence. 17% of patients experienced clinical recurrence 1 year after surgery. Secondary surgery for recurrence was not required. Planned postoperative ADA therapy reduced the incidence of endoscopic and clinical recurrence after bowel resection of Japanese patients with CD.
