Indications for and outcome of primary repair compared with faecal diversion in the management of traumatic colon injury.

AIM: Injuries of the colon are a serious sequel of abdominal trauma owing to the associated morbidity and mortality. This study aims to assess postoperative outcome and complications of faecal diversion and primary repair of colon injuries when applied according to established guidelines for the management of colon injuries.
METHOD: This retrospective study was conducted on 110 patients with colon injuries. Guided by estimation of risk factors, patients were managed either by primary repair alone, repair with proximal diversion or diversion alone.
RESULTS: There were 102 (92.7%) male patients and 8 (7.3%) female patients of median age 38 years. Thirty-seven were managed by primary repair and 73 by faecal diversion. Colon injuries were caused by penetrating abdominal trauma in 65 and blunt trauma in 45 patients. Forty-three patients were in shock on admission, and were all managed by faecal diversion. Forty patients developed 84 complications after surgery. Primary repair had a significantly lower complication rate than faecal diversion (P = 0.037). Wound infection was the commonest complication. The overall mortality rate was 3.6%.
CONCLUSION: Primary repair, when employed properly, resulted in a significantly lower complication rate than faecal diversion. Significant predictive factors associated with a higher complication rate were faecal diversion, severe faecal contamination, multiple colon injuries, an interval of more than 12 h after colon injury and shock.
