title: Evaluation of selective treatment of penetrating abdominal trauma.
abstract: OBJECTIVE
  In penetrating abdominal trauma, diagnostic imaging and the application of selective clinical management may avoid negative celiotomy and improve outcome.
  
  
  METHODS
  We prospectively observed patients with penetrating abdominal trauma over 15 months and recorded demographics, presentation, imaging, surgical procedure, and outcome. Patients who underwent immediate laparotomy were compared with patients who were observed and/or had a computed tomography (CT) scan. Outcomes of negative versus positive and immediate versus delayed celiotomy were compared. Chi-square and Student t tests were used. A p value of less than 0.05 was considered significant.
  
  
  METHODS
  A level 1 trauma center.
  
  
  METHODS
  Adult patients who presented with penetrating abdominal injury.
  
  
  RESULTS
  In all, 100 consecutive patients (mean age, 32 years) were included (male:female, 91:9; gunshot wound:stab wound, 65:35). Overall, 60 immediate and 10 delayed laparotomies were performed; 30 patients did not undergo surgery. Predictors of immediate celiotomy were hypotension (p = 0.03), anteriorly located entrance wounds (p = 0.0005), and transaxial wounds (p = 0.03). Overall morbidity and mortality was 32% and 2%, respectively. The negative celiotomy rate was 25%. Patients with a positive celiotomy had higher morbidity (p = 0.006) and longer hospital length of stay (p = 0.003) compared with negative celiotomy. A CT scan was employed in 32% of patients, with 100% sensitivity and 94% specificity. Delayed celiotomy (10%) did not adversely impact morbidity (p = 0.70) and was 100% therapeutic, with no deaths.
  
  
  CONCLUSIONS
  Nonselective immediate celiotomy for penetrating abdominal trauma results in a high rate of unnecessary surgery. Hemodynamically stable patients can safely be observed and/or have contrast CT scans and undergo delayed celiotomy, if indicated. This selective treatment had no adverse effect on patient outcomes and can potentially improve overall outcome.
