AbstractBackground and AimsInflammatory bowel disease (IBD) can lead to long-term complications that significantly impact patients’ quality of life and healthcare resource utilization. Prior studies have demonstrated improved short-term outcomes to early exposure of biologics in patients with Crohn’s disease (CD) but not in patients with ulcerative colitis (UC). However, there are conflicting data on impact of early intervention on longer-term adverse events. Therefore, we conducted a systematic review and meta-analysis assessing the impact of early biologic treatment on rates of IBD-related surgery.MethodsA systematic search was conducted in April 2022. Studies were included if biologic initiation was compared between patients starting early (<3 years of diagnosis or top-down treatment) vs later (>3 years of diagnosis or step-up treatment). Studies with <1 year of follow-up were excluded. The outcomes were colectomy and CD-related surgery for patients with UC and CD, respectively. Random-effects analyses were conducted to compare rates of IBD surgery between early and late biologic treatment.ResultsEighteen studies were included in the meta-analysis. Three studies included patients with UC and 15 studies included patients with CD. In patients with CD, early biologic therapy was associated with lower odds of surgery (odds ratio, 0.63; 95% confidence interval, 0.48-0.84) compared with late treatment. Conversely, in patients with UC, the odds of colectomy were increased (odds ratio, 2.86; 95% confidence interval, 1.30-6.30).ConclusionsEarly biologic treatment is associated with lower rates of surgery in patients with CD. In contrast, early biologic therapy appears to be associated with higher rates of colectomy in patients with UC, which may be confounded by disease severity.
