title: Fascial ultrasound for evaluation of anterior abdominal stab wound injury.
abstract: BACKGROUND
  Local stab wound (SW) exploration to assess abdominal fascial integrity is a highly invasive procedure frequently performed under demanding circumstances in the Emergency Department (ED). We hypothesized ultrasound (U/S) may be useful in the detection of fascial defects resulting from anterior abdominal stab injury, eliminating the need for local wound exploration
  
  
  METHODS
  Thirty-five hemodynamically normal patients evaluated at a Level I trauma center for anterior abdominal stab wounds were examined by U/S (8 mHz probe) for evidence of fascial violation. All patients were subsequently evaluated by local wound exploration
  
  
  RESULTS
  Fascial U/S had an overall sensitivity of 59% and specificity of 100%, (PPV 100%, NPV 59%) for detection of fascial SW defects compared with local wound exploration. The sensitivity of fascial U/S for stab wound evaluation varied directly with experience of the sonographer
  
  
  CONCLUSIONS
  A positive fascial U/S obviates the need for invasive SW exploration; however, a negative fascial U/S does not preclude the need for local wound exploration. Resident U/S training for specific penetrating injuries may reduce the need for abdominal SW fascial exploration in the ED.
