This is a case of traumatic bowel perforation at the duodenojejunal flexure. The localization of the hematoma in combination with the finding of both retroperitoneal and intraperitoneal extraluminal gas allowed us to pinpoint the location of the perforation, which was confirmed intraoperatively. The duodenojejunal flexure is a common location for traumatic bowel perforation due to its relative fixation by the ligament of Treitz, making it susceptible to injury by shearing forces.
