Biologic use is not associated with postoperative complications in patients with Crohn's disease undergoing stoma reversion

Purpose: Stoma creation is a common procedure in patients with Crohn's disease (CD), and early prophylaxis with biologics is recommended for high-risk patients. However, the effect of biologic exposure on morbidity after stoma closure remains unknown. Therefore, this study aimed to investigate the impact of biologic use on the occurrence of complications in CD patients following stoma closure.Methods: Consecutive patients diagnosed with CD who underwent ileostomy reversal at a tertiary care centre between 1 January 2013 and 1 December 2021, were included in the study. The primary outcome was the occurrence of 90-day postoperative complications.Results: The study included 347 eligible patients who underwent ileostomy reversal. There was no significant difference in terms of infectious complications, overall complications or length of postoperative stay between the biologic and non-biologic groups. Multivariate logistic regression analysis identified several predictors of postoperative morbidity, including preoperative haemoglobin levels below 100 g/L, CRP levels above 10 mg/L, anastomotic site, ileostomy-related infectious complications and albumin levels below 35 g/L.Conclusions: This study demonstrated that the use of biologics is not associated with adverse outcomes. However, such as high CRP levels, ileostomy-related infectious complications, hypoproteinemia, and hemoglobinemia, should be optimized prior to surgery to reduce postoperative morbidities.
