[Sonographically monitored intraoperative fine-needle aspiration cytology in pancreatic diseases]

Intraoperative fine needle aspiration cytology of the suspected pancreatic region was carried out in 14 patients with a preoperatively confirmed tumour of the pancreas. Sonographic assessment revealed a malignoma in six cases and chronic pancreatitis in eight cases. All sonographic findings were confirmed by puncture cytology; there was no false negative or false positive diagnosis. Fine needle aspiration cytology monitored via sonography can help to further reduce the incidence of false negative findings in intraoperative cytology and can exercise a decisive influence on surgical procedure by intraoperative sonography-monitored staging.
