Eligibility Criteria
Inclusion
- Scheduled surgery for Crohn's disease (CD) with ileocolonic resection. Diagnosis of CD confirmed at least 4 months prior to surgery based on radiology and/or endoscopy.
- Having an increased risk for postoperative relapse for any of the following reasons: (1) active inflammatory disease with C-reactive protein level (CRP) elevated above 10 mg/L, or the use of antibiotics, steroids or biological therapy including infliximab for active ileal disease within 2 months before surgery which were administered for Crohn's disease and not for another unrelated intercurrent inflammatory or infectious disease; (2) perforating disease defined as the presence of entero-enteric or enterocutaneous fistulas or perivisceral abscess formation within 2 months before surgery. Perianal fistulizing disease will not be considered as an indication of perforating disease in the ileum or right-sided colon. (3) Previous ileo-colonic resection, (4) active smoking, (5) age below 30.
- Males and females 16-75 years old.
- Curative surgical resection. All macroscopically inflamed colonic segments (except for anorectal involvement) are to be removed at surgery. Stricturoplasties in small bowel segments not involving the anastomotic region are allowed.
- Patients able to start oral nutrition and oral therapy within 14 days from surgery.
- Patients able and willing to give written informed consent
- Women of childbearing potential should have a negative pregnancy test at inclusion.
Exclusion
- Patients who only had strictureplasties or ileal/colonic resection without a new ileo-colonic anastomosis. Patients with ileorectal anastomosis.
- Patients with no increased risk of postoperative relapse as defined before.
- Patients with a known intolerance to azathioprine/6-mercaptopurine or with known homozygous thiopurine methyltransferase-low mutation.
- Patients in whom more than 100 cm of small bowel has been previously resected.
- Patients with active perianal disease or colorectal stenosis precluding ileocolonoscopy
- Patients with sepsis or other postoperative complications necessitating use of antibiotics for more than 14 days after surgery.
- Patients with liver test abnormalities (serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, alkaline phosphatase, bilirubin \> 2 ULN), leucopenia (\<3000 white blood cell count /µL, \<1500 neutrophils /µL), thrombopenia with \< 50.000 platelets/mm3.
- Patients with severe renal, pulmonary or cardiac disease.
- Pregnant or lactating women.
- Ongoing alcohol or substance abuse.
- Ongoing or recent (within 6 months) infectious disease (viral hepatitis, tuberculosis, AIDS, Herpes zoster related disease).
- Known malignancy 5 years from surgery except for superficial epithelioma of the skin with curative resection.
