Meta-analysis of Histological Margin Positivity in the Prediction of Recurrence After Crohn’s Resection

BACKGROUND: Despite significant advances in the medical management of Crohn’s disease, many patients will require intestinal resection during their lifetime. It is disappointing that many will also develop disease recurrence. OBJECTIVES: The current study utilizes meta-analytical techniques to determine the effect of positive histological margins at the time of index resection on disease recurrence. DATA SOURCES: Embase, Medline, PubMed, PubMed Central, and Cochrane databases were searched using a Boolean search algorithm for articles published up to August 2017. STUDY SELECTION: Meta-analysis was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. MAIN OUTCOME MEASURES: Databases were searched for studies reporting the outcomes for patients with Crohn’s disease undergoing primary resection that correlated resection margin status with disease recurrence. Results were reported as pooled ORs with 95% CI. RESULTS: A total of 176 citations were reviewed; 18 studies comprising 1833 patients were ultimately included in the analysis, with a mean rate of histopathological margin positivity of 41.7 ± 17.4% and a pooled mean follow-up of 69 ± 39 months. Histopathological margin positivity was associated with a higher rate of overall recurrence (OR, 1.7; 95% CI, 1.3–2.1; p
