A mass survey for pancreatic cancer using ultrasonography (US) is still necessary for improvement. We found 753 pancreatic abnormalities (0.9%) by US in consecutive 87, 597 subjects undergoing periodical health examination in Chubu Health Care Center during 1993-2002. demonstrated 544 of dilatation of pancreatic duct (72%), 72 of pancreatic cyst (10%), 56 of pancreatic tumor (7%), 21 of pancreatic calcification (3%) and 8 of pancreas swelling (1%). Further examinations revealed various pancreatic diseases, including 11 of intraductal papillary tumors, 4 of pancreatic carcinoma, 2 of solid cystic tumor of pancreas, 1 of islet cell tumor and 1 of serous cystadenoma. In patients with pancreatic cancer, one died with hepatic metastasis after pancreatoduodenectomy, and one is surviving for 6 years after distal pancreatectomy. Two had unresectable cancer. It is difficult to detect a resectable small pancreatic cancer, because patients suffering from pancreatic cancer are older than those subjects of mass survey at present. Also, it is difficult to establish high-risk group of pancreatic cancer. Subsequent further examinations by endoscopic ultrasonography (EUS) or enhanced computed tomography (CT) may be efficient tools to find a small respectable cancer.
