[A method for percutaneous thin-needle biopsy of the pancreas aimed by ultrasound (author's transl)].

Percutaneous biopsy of the pancreas with a fine needle aimed by ultrasound was carried out on 26 patients with sonographically proven carcinoma of the pancreas. The accuracy of this method was correlated with other radiological techniques. Needle biopsy of the pancreas proved an informative and economical procedure, since the sonographic demonstration of a pancreatic mass otherwise requires additional radiological and endoscopic investigations.
