BackgroundManagement of colon injuries has significantly evolved in the recent decades resulting in considerably decreased morbidity and mortality. We set out to investigate penetrating colon injuries in a high-volume urban academic trauma center in South Africa.MethodsAll patients with penetrating colon injuries admitted between 1/2015 and 1/2018 were prospectively enrolled. Data collection included demographics, injury profile and outcomes. Primary outcome was in-hospital mortality. Secondary outcome was morbidity.ResultsTwo-hundred and five patients were included in the analysis. Stab and gunshot wounds constituted 18% and 82% of the cases, respectively. Mean age was 28.9 (10.2) years and 96.1% were male. Median injury severity score (ISS) and penetrating abdominal trauma index (PATI) were 16 (9-25) and 19 (10-26), respectively. A total of 47.8% of the patients had a complication per Clavien-Dindo classification. Colon leak rate was 2.4%. Wound and abdominal organ/space infection rate was 15.1 and 6.3%, respectively. Overall in-hospital mortality was 9.3%. Risk factors for mortality were higher ISS and PATI, shock on admission, need for blood transfusion, intra-abdominal vascular injury, damage control surgery, and extra-abdominal severe injuries.ConclusionsContemporary overall complication rate remains high in penetrating colon injuries, however, anastomotic leak rate is decreasing. Colon injury associated mortality is related to overall injury burden and hemorrhage rather than to colon injuries.Copyright © 2020 Elsevier Ltd. All rights reserved.
