Colon trauma is a clinical entity that can occur in both civilian and military contexts. Overall mortality is 8.2% and its incidence is 0.64%, of which 43.9% is caused by blunt trauma and 56.1% by penetrating trauma. Some studies have found an increase in mortality in cases of blunt trauma, especially in patients over 65 years of age and in those with a high ISS.

Observational analytic study of adult patients with surgically confirmed colon trauma treated at our institution. Clinical records and operative notes were reviewed. The primary outcome was surgical site infection (SSI) within 30 days, defined by CDC criteria. Predictor variables included mechanism of injury, vital signs on admission, presence of peritonitis, need for intensive care, type of surgical procedure, and hospital stay.

A significant positive correlation was found between the following factors: in-hospital stay (HIE) greater than 10 days (OR 4.95 [CI95 1.2-19.06]; p=0.016), penetrating trauma by firearm projectile (OR 8.35 [CI951.61-43.27]; p=0.006), generalized peritonitis (OR 12.35 [CI951.44-105.44]; p=0. 007), heart rate greater than 90 beats per minute on admission (OR 4.58 [CI95 1.18-17.6]; p=0.022), requirement of intensive therapy (OR 6.12 [CI951.42-26.32]; p=0.010) and performance of colostomy in the first surgical procedure (OR 4.50 [CI951.21-16.62]; p=0.020), with the development of surgical site infection.

The results demonstrated that there are factors that elevate the risk of surgical site infection in patients diagnosed with colon trauma.
