title: [Diagnostic accuracy of fine needle aspiration cytology guided by ultrasonography in intra-abdominal and retroperitoneal lesions].
abstract: Evaluation of the fine needle aspiration cytology guided by ultrasonography in the diagnosis of abdominal and retroperitoneal tumors.
  
  
  METHODS
  Transversal study of diagnostic standard-criterion test.
  
  
  METHODS
  Ultrasonographic Unity Digestive Disease Department. Hospital Oncológico Padre Machado.
  
  
  METHODS
  98 patients with intraabdominal and retroperitoneal lesions.
  
  
  METHODS
  Fine needle aspiration cytology guided by Ultrasonography. INDICE TEST: Laparoscopy and/or laparotomy.
  
  
  METHODS
  Estimation of sensibility (S), Specificity (E), Efficacy (Ef), positive predictive value (VPP), negative predictive value (VPN), measure of false positives (TFP) and measure of false negatives (TFN) by diagnosis method.
  
  
  RESULTS
  VP: 81%; VN: 12%; FP: 1%; FN: 6%; S: 93%; E: 92.3%; Ef.: 97%; VPP: 98.7%; VPN: 66%; TFP: 1.25%; Benign lesions: 22.5%; Malignancy lesions: 65.5%; non lesions: 12%; complications: severe: 1%, non significance: 5%.
  
  
  CONCLUSIONS
  Fine needle aspiration cytology guided by ultrasound has high sensibility, specificity, efficacy, with low value of false positive. However, it has high incidence of false negatives and negative predictive value. We recommend diagnostic procedures when the suspicion of tumor is high did the cytology is negative.
