Abstract

UNLABELLED

Evaluation of the fine needle aspiration cytology guided by ultrasonography in the diagnosis of abdominal and retroperitoneal tumors.

DESIGN

Transversal study of diagnostic standard-criterion test.

PLACE

Ultrasonographic Unity Digestive Disease Department. Hospital Oncológico Padre Machado.

SAMPLE

98 patients with intraabdominal and retroperitoneal lesions.

INTERVENTION

Fine needle aspiration cytology guided by Ultrasonography. INDICE TEST: Laparoscopy and/or laparotomy.

MEASUREMENTS

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.
