Gunshot wounds of the colon: role of primary repair.

This is a prospective study of 100 patients with bullet injuries of the colon. Primary repair was performed except in cases of severe colonic damage requiring colectomy or in the presence of disseminated gross peritoneal contamination. Primary repair was performed in 76% with an incidence of abdominal sepsis of 11.8%. The remaining 24% of the patients had a colostomy and the incidence of abdominal sepsis was 29.2% (P < 0.05). Left-sided colonic injuries, multiple colonic perforations, shock on admission, delay > 6 h, more than two associated intra-abdominal injuries, high Injury Severity Score (ISS), and high Penetrating Abdominal Trauma Index (PATI), are not in themselves contraindications for primary repair.
