A 22-year-old male presented from the scene as a trauma after motorcycle crash. He was tachycardic and hypertensive with obvious extremity injuries and a circular handlebar injury to the midabdomen.  He underwent CT scan with intravenous contrast. CT revealed free intraperitoneal air with intraluminal high-density material consistent with contrast in the small and large bowel. However, the patient did not receive oral contrast, nor had he had any recent imaging. He was taken to the operating room and underwent exploratory laparotomy.  A jejunal perforation was identified and resected, but did not completely explain the intraluminal contrast.  Only after exploring the remaining GI tract, mobilizing the right colon, and performing a Kocher maneuver, was it possible to identify the etiology of the intraluminal contrast. There was a 3 centimeter duodenal perforation with an adjacent actively bleeding branch off of the superior mesenteric vein. The venous branch was suture ligated and the duodenal perforation closed in two layers.  The patient was left in discontinuity with an open abdomen, secondary to intraoperative pressor requirements, and was taken the following day to the operating room for reanastomosis and a second look.  During that procedure, the duodenal anastomosis was evaluated and appeared healthy and intact.  There was no evidence of ongoing bleeding from the previously ligated mesenteric vein branch.  No further venography was performed.

Due to timing of the CT imaging, there was no evidence of extravasation of IV contrast from the venous injury into the duodenal perforation, but there was clear evidence of contrast in the GI tract in the absence of PO contrast administration.  The injury pattern is somewhat unique in that the venous bleeding was entirely into the GI tract rather than intraabdominal.  However, given the trajectory of the high impact blunt injury from the motorcycle handlebar, the venous branch injury overlying the duodenal branch injury is easily explained.  The decision for operative intervention was based on free air and unexplained intraluminal contrast in the GI tract.  Although the jejunal perforation explained the free air, further exploration was necessary for discovering the etiology of the intraluminal contrast.  This is a useful case presentation on the importance of performing a thorough exploration of the entire GI tract for all trauma patients.
