IntroductionThere is limited evidence to suggest that patients with penetrating colon injury have higher complication rates when there is concomitant small bowel (SB) injury.AimWe performed a retrospective study looking at outcomes of penetrating colonic trauma in patients with- and without concomitant SB injury.MethodsWe interrogated our electronic registry over an eight-year period (2012-2020) for all patients over 18 years who had sustained penetrating colon injury and who had survived beyond 72 h. Demographic data, admission physiology, and Injury Severity Score (ISS) were recorded. Two groups of patients were observed: those with colonic injury (no SB injury) and those with combined colon and SB injury. Outcomes observed included leak rates, length of Intensive Care Unit (ICU) stay, length of hospital stay (LOS), morbidity and mortality.ResultsA total of 450 patients were eligible for analysis, of which 257 had colon injury without SB injury and 193 had a combination of colon and SB injury. There was no difference in mechanism of injury between groups. Admission physiology was similar between groups but arterial blood gas values were worse in the combined group. Rates of damage control surgery and ICU admission were higher in the combined group. Primary repair was done in equal proportions between groups but anastomosis was more frequently performed in the combined group. There was no difference in complication rates, including gastro-intestinal complications and suture line leaks. Length of ICU stay, LOS, and mortality were similar between groups. Univariable analysis demonstrated that the presence of concomitant small bowel injury was not an independent risk factor for colonic suture line failure or death.ConclusionThere is no evidence from this data that the presence of a combined penetrating colon and SB injury should change management priorities. Each injury should be treated on its own merit, in the context of the patient's physiology.Copyright © 2021. Published by Elsevier Ltd.
