[Morphological diagnosis of abdominal cavity tumors using fine-needle aspiration biopsy controlled by ultrasound].

Thin needle biopsy under ultrasound control was carried out in 142 patients. Cytologic evaluation (142 samples) was supplemented by histologic study in 111 cases. Morphologic assessment of the biopsy specimens proved sufficient for an adequate diagnosis in 93.6% of cases, represents an objective method of verification of ultrasound findings in primary and metastatic tumors of the peritoneum providing evidence for their tissue origin and histologic form.
