Input: Six trials involving 705 patients were included. Mortality was not significantly different between groups, which was low in both the primary repair (1.94%) and the diverted groups (1.74%). The Peto OR for mortality was 1.22 (95% CI 0.40 to 3.74). However, the primary repair group experienced a significantly lower rate of complications (Peto OR 0.54; 95% CI 0.39 to 0.76), total infectious complications (Peto OR 0.44; 95% CI 0.17 to 1.1), abdominal infections including dehiscence (Peto OR 0.67; 95% CI 0.35 to 1.3), abdominal infections excluding dehiscence (Peto OR 0.69; 95% CI 0.34 to 1.39), wound complications including dehiscence (Peto OR 0.73; 95% CI 0.38 to 1.39), and wound complications excluding dehiscence (Peto OR 0.67; 95% CI 0.32 to 1.39). Statistical significance favoring primary repair over fecal diversion was achieved for all outcomes related to abdominal infections and wound complications when one study was excluded for both clinical and statistical heterogeneity in the sensitivity analysis. Meta-analysis of currently published randomized controlled trials favors primary repair over fecal diversion for penetrating colon injuries.
Output:

The review authors searched the medical literature and found six controlled studies in which patients were randomized to primary repair or fecal diversion. Results were reported for a total of 705 patients. The two groups sustained significant injuries with the primary repair patients at least as ill as the diverted patients. The studies were reported from 1979 to 2002 and involved increasingly 'high risk' patients. Five were conducted in the United States and one in South Africa. Primary closure was at least as safe as fecal diversion. The number of deaths was similar in both the primary repair (1.94%) and the diverted groups (1.74%). Total complications, total infectious complications, abdominal infections and wound complications all favored primary repair. The studies did not adequately report colostomy closure for trauma-related colostomies, which can itself result in complications and significant illness.
