[90 fine-needle punctures for diagnosis of the upper abdomen under ultrasonic guidance. Contribution of cyto- and histologic analysis].

Fine needle puncture was performed of upper abdomen in 19 cases. The method is rapid, reliable, of low cost and only weakly traumatic. The recent possibility of coupling histologic and cytologic analysis with fine needles provides improved results by increasing diagnostic precision and identification of malignant tumors and benign tumors of difficult cytologic diagnosis.
