The impact of pre-operative biologic therapy on post-operative surgical outcomes in ulcerative colitis: a systematic review and meta-analysis.

ABSTRACT: Background and aims: Biologic therapy has emerged as an effective modality amongst the medical treatment options available for ulcerative colitis (UC). However, its impact on post-operative care in patients with UC is still debatable. This review evaluates the risk of post-operative complications following biologic treatment in patients with UC.

Methods: A systematic search of the relevant databases was conducted with the aim of identifying studies that compared the post-operative complication rates of UC patients who were either exposed or not exposed to a biologic therapy prior to their surgery. Outcomes of interest included both infection-related complications and overall surgical morbidity. Pooled odds-ratio (OR) and 95% confidence intervals (CI) were calculated using Review Manager 5.3.

Results: In all, 20 studies, reviewing a total of 12,494 patients with UC, were included in the meta-analysis. Of these, 2254 patients were exposed to a biologic therapy prior to surgery. The pooled ORs for infection-related complications (n?=?8067) and overall complications (n?=?11,869) were 0.98 (95% CI 0.66-1.45) and 1.14 (95% CI 1.04-1.28), respectively, which suggested that there was no significant association between the use of pre-operative biologic therapy and post-operative complications. Interestingly, the interval between the last dose of biologic therapy and surgery did not influence the risk of having a post-operative infection.

Conclusions: This meta-analysis suggests that pre-operative biologic therapy does not increase the overall risk of having post-operative infection-related or other complications. PROSPERO registration id-CRD42019141827.
