Aim Surgical site infections are disproportionately common after colorectal surgery and may be largely preventable. The objective of this retrospective cohort study was to determine the effect of oral antibiotics and mechanical bowel preparation on surgical site infections. Method A retrospective study of a consecutive series of elective colonic and rectal resections following an Enhanced Recovery After Surgery pathway, which also included mechanical bowel preparation, from 1 September 2014 to 30 September 2017. The addition of oral antibiotics (neomycin and metronidazole) to the mechanical bowel preparation procedure was assessed. Development of surgical site infections within 30 days was the main outcome measured. The secondary outcome was assessment of possible surgical site infection predictors. Results Seven‐hundred thirty‐two patients were included: 313 (43%) preintervention (mechanical bowel preparation only); and 419 (57%) postintervention (mechanical bowel preparation plus oral antibiotics). Surgical site infection rates preintervention and. postintervention were: overall, 20.8% vs 10.5%, P  < 0.001; superficial, 10.9% vs 4.3%, P  < 0.001; and organ space, 9.9% vs 6.2%, P  = 0.03. Subgroup analysis of colonic resections revealed a significant reduction in overall (17.1% vs 6.8%), superficial (10.7% vs 4.3%) and organ space (6.4% vs. 2.6%) infections. Rectal resections had significant reduction in overall (26.2% vs 15.3%) and superficial (11.1% vs 4.4%) infection rates but not in organ space infections (15.1% vs 10.9%). Multivariate regression analysis revealed open vs minimally invasive surgery ( P  < 0.001) and omission of oral antibiotics ( P  = 0.004) as independent predictors of surgical site infections. Conclusion Administration of oral antibiotics resulted in significant reduction of superficial and organ space infections after colonic resection; after rectal resection, significant reduction only of superficial infections was found.
