Percutaneous aspiration biopsy of the pancreas under ultrasonic guidance

Abstract

Fine-needle aspiration biopsy for cytologic diagnosis was performed on seven patients suspected of having pancreatic tumors. A 23-gauge biopsy needle was accurately placed in the suspicious lesion under ultrasonic guidance. Six patients had tumors; of these, five had a definite cytologic diagnosis, and the sixth was suspicious of tumor. There was no morbidity associated with the procedure in these patients. Although fine-needle biopsy is not expected to prolong life in patients with pancreatic tumors, it does eliminate the need for more complicated, expensive, uncomfortable and hazardous diagnostic procedures. In many cases exploratory surgery may be obviated.
