Endoscopic Retrograde Cholangiopancreatography(ERCP) is one of the important diagnostic methods for pancreaticcancer. It has an essential role in the early detection of pancreatic cancer. The ERCP findings of 35 cases ofpathologically proven pancreatic cancer during the period of five and a half years from April 1977 through Nov.1982 at Kwangju Christian Hospital were studied. The resuls were as follows; 1. The ratio of male of female was3.4:1, and most of the patients were over 40 years of age (88.5%). 2. The locations of the lesions were the headin 28 cases (80%), the body in 7 cases(20%), and the ail in 3 cases (8.6%). 3. The ERCP findings of pancreaticcancers were as follows; 1) Encasement or obstruction of common bile duct, 18 cases (51.4%). 2) Obstruction ofpancreatic duct, 16 cases (45.7%). 3) Irregular stenosis of pancreatic duct, 8 cases (22.3%). 4) Double duct sign,7 cases (20%). 5) Diffuse narrowing of pancreatic duct, 2 cases (5.7%).
