Repair by Primary Closure of Traumatic Blunt Duodenal Injuries: Simple is Not Always Safe.

ABSTRACT

INTRODUCTION: Recent literature on managing traumatic duodenal injuries suggests the superiority of primary repair. We hypothesized that duodenal trauma repair by primary closure might not be a safe strategy in an environment dealing predominantly blunt injuries with limited resources. METHODS: Data analysis was done from the prospectively maintained trauma registry. The study period chosen was from January 1, 2014 to December 31, 2018. Data of 63 patients were analyzed for demographics, injuries, management, and outcome. Logistic regression was used to identify mortality predictors. RESULTS: The most common mechanism of injury was blunt (56/63, 88.9%). Forty (63.5%) patients had associated intraabdominal injuries. The most common American Association for the Surgery of Trauma grade of injury to the duodenum was three in 21 patients. Univariate analysis showed that mortality was associated with hypotension on presentation, higher duodenal grade, associated abdominal vascular injuries, primary closure, and duodenal leak. Logistic regression showed associated associated abdominal vascular injuries, primary closure, and leak remained significant predictors of mortality. CONCLUSIONS: Primary repair was found to be an independent predictor of mortality. A patient's physiology is a critical determinant of the outcome. Liberal use of tube duodenostomy over primary repair seems reasonable for blunt duodenal injury management.
