Enterolith formation is a rare condition precipitated by decreased bowel motility. It may cause obstruction or other complications and the diagnosis usually is confirmed after surgery and analysis of the stones or fragments. It is often seen in association with intestinal abnormalities such as diverticula and inflammation or in biliary tract fistulas where stones migrate to the duodenum and small bowel. We report an unusual case of a primary true enterolith formation in a patient without any underlying bowel condition or any previous surgery.

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.
