    Abstract:
    Intraoperative realtime high resolution ultrasound scanning of the pancreas seems to be a new and promising procedure. We have performed it in 28 patients: the normal ultrasound picture of pancreatic ducts and parenchyma was defined in 9 patients without pancreatic disease; in 19 patients with pancreatic disease, intraoperative ultrasound was compared with preoperative ultrasound examination. Seven of 8 patients with pancreatic carcinoma and 4 of 6 with calcifying chronic pancreatitis had positive findings, respectively. In 3 cancer patients, intraoperative ultrasound investigation avoided a long and unavailing dissection of the tumor by revealing extensive spread. In selected cases, intraoperative sonography allowed to characterize and to localize pancreatic carcinoma: portal vein invasion, relationship of the tumor to the duct of Wirsung and small hepatic metastases. In chronic pancreatitis, intraoperative ultrasound information concerning the dimensions of the pancreatic duct, the structure and the localization of pseudocysts was comparable to that obtained by radiological opacification. Furthermore, intraoperative ultrasound exploration guided proper incision and evacuation of pancreatic pseudocysts in two patients. Operative ultrasound seems to us to be mandatory during pancreatic surgery. Further experience with this technique is needed in a larger number of patients. However, we believe that it could replace intraoperative cholangiography and pancreaticography in the assessment of extension and complications of pancreatic disease.
