Abstract
Duodenal trauma resulting in perforation is rare and management can be challenging due to injuries in other organs and vascular structures. Primary repair is the preferred option and is technically feasible even in cases with large defects. In more complex injuries with pancreaticobiliary tract involvement, damage control techniques and staged procedures may be required. Triple tube drainage with tube gastrostomy, tube duodenostomy, and feeding jejunostomy can benefit the adequate decompression of the duodenum and protect the primary repair suture line. We report the case of a 35-year-old male patient with perforation in the second part of the duodenum following a gunshot injury, who was managed with primary repair and triple tube drainage.
