[Accuracy of ultrasound-guided fine needle biopsy in pancreas cancer--effect of puncture frequency and character of puncture material].
There is no agreement upon the number of punctions guided by ultrasonography needed to establish cytologically the diagnosis of pancreas carcinoma. Therefore reliability of the method as being dependent upon the number of punctions in 43 maligne tumors of the pancreas was evaluated. Performing two to five punctions yielded significantly better results than just one. In addition the macroscopic aspect of the aspirate is important.
