Intestinal stenosis from mesenteric injury after blunt abdominal trauma
- 70 Downloads
We report a case in which blunt abdominal trauma resulted in injury to the mesentery with subsequent ischemic stricture of the adjacent small bowel. We present CT images at the time of trauma and 5 weeks later when clinical signs of intestinal obstruction occurred. We include images of enteroclysis and angiography of this uncommon sequela of blunt abdominal trauma. At surgery, a stenotic small bowel loop was found adjacent to a healed defect in the mesentery. Histological examination of the resected segment showed mucosal and submucosal ischemia with mucosal ulceration, mural inflammation, and fibrosis. Posttraumatic intestinal stenosis subsequent to a mesenteric tear should be included in the differential diagnosis in a patient with a history of blunt abdominal trauma and signs of intestinal obstruction.
