We describe a new case of duodenal wound with complete transection in a 22-year-old patient following a motorcycle accident. He presented to the emergency room of the rural Regional Hospital of Edéa in Cameroon with a clinical picture of acute abdomen and post-trauma hemodynamic instability. A peritoneal puncture brought back an incoagulable blood. An exploratory laparotomy revealed a large hemoperitoneum mixed with food debris. A tear of the omentum and transverse mesocolon and a complete section of the third duodenum at the beginning of its free portion were observed. The surgeon performed emergency closure of both duodenal stumps and performed an isoperistaltic lateral gastrojejunal bypass. A transfer to a specialized center for a more anatomical continuity was considered, but the imminence of a humanitarian mission in the hospital prompted the surgeon to seize the opportunity of this mission for the reoperation. This surgical revision was performed on the fifth postoperative day. A resection of the distal duodenal stump and the adjacent jejunal segment including the anastomosis was performed. Continuity was restored by a mechanical duodenal-jejunal anastomosis. The patient was discharged on the 18th postoperative day. This type of lesion is difficult to manage in an emergency situation in a structure with limited technical resources. Unfortunately, surgeons treating polytraumatized civilians are encountering an increasing number of blunt duodenal wounds requiring laborious management.
