In the case of 10 to 15% of surgical patients with a pancreatic disorder an intraoperative diagnosis had to be made when a preoperative diagnosis had not yielded a definite result. Fine needle aspiration biopsy ( FNAB ) of the pancreas provided the basis for intraoperative differentiation of malignant and benign pancreatic processes. 244 pancreatic biopsies were carried out in 100 patients. It was possible to make a statement in 99% of the cases, with 65 malignant and 35 benign changes. In 83% the cytological diagnosis was correct; the method yielded incorrect-negative results in 7% of the cases. In 9% the presence of tumour cells was only suspected. There were no incorrect positive cancer diagnoses. FNAB caused no postoperative complications. Intraoperative bleeding after FBAB had to be stopped with a suture in one case. Transitory, asymptomatic hyperamylasemy must be expected in 25% of the patients after FNAB . This diagnostic technique is recommended in preference to the histological tissue removal methods because of its low risk factor. At least 2 biopsies of the suspect area with 2 smears are required, as a training in this diagnostic technique.
