Beskrivelse
Inclusion Criteria:
- Age ≥18 years.
- Diagnosis of Crohn's disease according to the European Crohn's and Colitis Organisation (ECCO) guideline criteria, based on clinical, laboratory, endoscopic, radiologic, and histopathologic findings.
- Underwent Crohn's disease-related intestinal resection, including ileocolonic resection, segmental small bowel resection, or segmental colonic resection.
- Initiated postoperative prophylactic biologic therapy within 6 weeks after surgery.
- Maintained postoperative prophylactic biologic therapy for at least 3 to 6 months.
- Completed at least one evaluable postoperative ileocolonoscopy within 6 to 12 months after surgery for assessment of the Rutgeerts score, or had available clinical, radiologic, ultrasonographic, or laboratory data for evaluation of clinical recurrence.
Exclusion Criteria:
- Diagnosis of other intestinal diseases, including intestinal Behçet's disease, ulcerative colitis, intestinal tuberculosis, or intestinal malignancy.
- Intestinal surgery mainly performed for non-IBD conditions, such as intestinal malignancy.
- No postoperative endoscopic evaluation within 6 to 12 months after surgery, or endoscopic quality insufficient for Rutgeerts score assessment, and lack of adequate clinical, radiologic, ultrasonographic, or laboratory data for recurrence assessment.
- Irregular use of postoperative prophylactic therapy due to severe comorbidities, serious infection, or other reasons, making treatment efficacy difficult to evaluate.
- Other conditions considered by the investigators to be inappropriate for inclusion.

Postoperative anti-TNF biologics group
Patients with Crohn's disease who underwent CD-related intestinal resection and initiated postoperative prophylactic anti-TNF biologic therapy within 6 weeks after surgery, including infliximab or adalimumab.
All treatments were prescribed as part of routine clinical care, and this retrospective observational study did not assign any intervention.
|
Infliximab was used as postoperative prophylactic biologic therapy for Crohn's disease according to routine clinical practice.
The recommended regimen was 5 mg/kg intravenously at weeks 0, 2, and 6, followed by maintenance treatment every 8 weeks.
Adalimumab was used as postoperative prophylactic biologic therapy for Crohn's disease according to routine clinical practice.
The recommended regimen was 160 mg subcutaneously at week 0, 80 mg at week 2, and 40 mg every 2 weeks from week 4 onward.
|
|
Postoperative non-anti-TNF biologics group
Patients with Crohn's disease who underwent CD-related intestinal resection and initiated postoperative prophylactic non-anti-TNF biologic therapy within 6 weeks after surgery, including vedolizumab or ustekinumab.
All treatments were prescribed as part of routine clinical care, and this retrospective observational study did not assign any intervention.
|
Vedolizumab was used as postoperative prophylactic biologic therapy for Crohn's disease according to routine clinical practice.
The recommended regimen was 300 mg intravenously at weeks 0, 2, and 6, followed by maintenance treatment every 8 weeks.
Ustekinumab was used as postoperative prophylactic biologic therapy for Crohn's disease according to routine clinical practice.
The recommended regimen included a weight-based intravenous induction dose, followed by 90 mg subcutaneously every 8 weeks.
