COMPARISON OF MRCP AND ERCP IN DIAGNOSIS OF CHRONIC PANCREATITIS / 解放军医学杂志

ABSTRACT

The aim of this study was to evaluate the diagnostic value of MRCP and ERCP in patients with chronic pancreatitis. A total of 262 patients were diagnosed as charonic pancreatitis by clinical feature, screenage and pathology from January 1993 to December 2001 in Changhai Hospital. Among them 120 patients who had been subjected to MRCP and ERCP were analyzed retrospectively. There were 106 patients discovered constriction, dilatation and calculuses of pancreatic, bile ducts, and diagnosed chronic pancreatitis by MRCP, the sensitivity was 88 3%. Also there were 108 patients discovered cholangiopancreatic disorder and diagnosed chronic pancreatitis by ERCP, the sensitivity was 90%. No statistical difference was found between interpretations based upon MRCP and ERCP( P =0 678). Results from both MRCP and ERCP discovered 96 patients with chronic pancreatitis; the agreement rate in diagnosis was 81 4%. Furthermore, 118 patients were diagnosed chronic pancreaitis by MRCP or ERCP, and the sensitivity was up to 98 3%. In addition, all examined patients were succeeded and no severe complications were found in regard to examination itself. So MRCP is as sensitive as ERCP when detecting chronic pancreatitis. Furthermore, it is feasible to presume that all chronic pancreatitis cases could be diagnosed by MRCP combined with ERCP.
