Inflammatory bowel disease (IBD) is a chronic, idiopathic inflammatory disease of the gastrointestinal tract. Patients with IBD are diagnosed with either Crohn’s disease (CD) or ulcerative colitis (UC). Tjibbe Gardenbroek focuses on the developments in the surgical treatment of patients with inflammatory bowel disease and familial adenomatous polyposis and concentrates on new developments in surgical techniques. He also throws light on the appendix and its role in UC. There is evidence that an appendectomy protects against development of UC and may influence the disease course of UC.
