Abstract
CT examination after ERCP (FRCP-CT) is a new trial for image diagnosis of biliopancreatic disorder and extrapancreatic mass. In Cancer Institute Hospital, ERCP-CT was carried out in 57 cases during the past 2 years and 4 months (Table 1). To obtain clear ERCP-CT image it is necessary to start CT scanning after ERCP as quickly as possible. To prevent artifacts on CT image, some considerations such as use of diluted contrast medium and less air insufflation are also necessary. The efficacy of ERCP-CT for pancreatic cancer and chronic pancreatitis was studied in this paper. ERCP-CT was useful for diagnosis of pancreas disease with following changes. Pancreatic cancer; 1. Those with cystic change around stenosis of main pancreatic duct (Figure 2-a, B) 2. Those with displacement and stenosis of main pancreatic duct (Figure 2-a, C) Chronic pancreatitis ; 1. Those with localized stenosis of main pancreatic duct (Figure 2-b, b) 2. Those with cyst, especially in the pancreas tail (Figure 2-b, c) As a result of evaluating ERCP-CT of pancreatic cancer (larger than 2 cm in diameter) and chronic pancreatitis, we have come to the conclusion that ERCP-CT is useful for diagnosis of small pancreatic cancer.
