title: [Cytology and biopsy by fine needle aspiration with ultrasound guidance in abdominal tumors].
abstract: To determine the value of fine needle aspiration biopsy (FNAB) we selected 53 patients with liver, pancreas and other abdominal tumors, their diagnosis was made on clinical and ultrasound grounds, we performed FNAB in all these patients. The specimens were sent for cytology and histopathology. 33 out of 53 cases were reported as liver cancer: true positives: 29, false negative 2, and true negatives: 2, for sensibility; 93% specificity: 100%. 15 cases were pancreatic cancer, true positives: 11, true negatives: 3; with 1 false negative, sensibility 91%; specificity 100%. 5 cases were tumors from other abdominal cavity locations (true positives: 3, false negatives: 2; sensibility: 60% specificity: 100%. All these results were well correlated with surgery, clinical follow up and other diagnostic methods ERCP, CT, Laparoscopy. We conclude (FNAB) has a high sensibility and specificity and should be used as a routine procedure in the study of abdominal tumors. No false positive was reported.
