Comparative Analysis of the Carcinoma of Pancreatic Head Between SCT Findings and Surgery or Pathology

Objective To evaluate the value of spiral CT scan in the diagnosis of the carcinoma of pancreatic head and to improve the accurate rate of the diagnosis of the carcinoma of pancreatic head by CT scan.Methods Twenty-five cases of the carcinoma of pancreatic head proved by surgery or pathology from 1998 July to 2004 February were analyzed.There were 24 cases of adenocarcinoma and 1 case of adenocystic carcinoma.The results of these cases were analyzed retrospectively with the spiral CT findings and the clinical characteristic according to surgery and/or pathology using SPSS.Results All cases of the carcinoma of pancreatic head showed lower density after enhancement.There were 18 cases with dilated pancreatic duct,10 cases with dual-duct sign,22 cases with 4 to 6 rings of dilated common bile duct,15 cases with the atrophy of pancreatic body and tail.The common bile duct of 21 cases and the intrahepatic bile duct of 19 cases were media or heavy-degree dilation.The dilated intrahepatic bile duct of 19 cases was proportional with dilated extrahepatic one.All associated with dilated gallbladders.Conclusion Spiral CT dual-phase scan is an evexamination modality in the diagnosis of the carcinoma of pancreatic head and using SCT scan predicts whether tumors are resectable before surgery.
