- W2356992011 abstract "Objective To evaluate the necessity of the routine application of MRCP(magnetic resonance cholangiopancreatography) in patients with gallstone disease to diagnose common bile duct(CBD) stones.And to study the efficacy of a logistic regressive predict model for diagnosing CBD stones.MethodsA retrospective analysis was performed on 1 030 patients(the control group) with gallstones routinely underwent MRCP before cholecystectomy.And a prospective study was carried out in 366 patients(treatment group) with gallstones firstly hospitalization.ResultsThe positive incidence of CBD stones was 7.8%(80/1030),the false positive incidence was 0%(0/80),and the false negative incidence was 0.8%(8/950) in the control group.The predict model for CBD stones consists of 5 variables that are ultrasonographically showing CBD stones or bile duct dilation(BDD),aged above 65 years,fever,serum alkaline phosphatase level greater than 121 IU/L and serum amylase level above 100 U/L.The prediction entry threshold of the predict model was 6%(P0.05).In 174 patients who did not undergo the MRCP because of their prediction probability below the entry threshold,only one patient(1/174) suffered a postoperative right-upper abdominal colic and was diagnosed as CBD stone by MRCP.The positive rate of MRCP diagnosing CBD stones in the treatment group was obviously higher(P0.01).The mean hospitalization course in the control group was obviously longer than that in the treatment group,while the average total costs in hospital of the patients in treatment group was markedly lower(P0.01).ConclusionIt is unnecessary for every patient with gallstone disease to perform the routine MRCP.But for the patients with gallstone disease whose prediction probability for CBD stones is above the entry threshold,the MRCP is recommended to confirm the presence or absence of CBD stones.The application of the new predict model for CBD stones combined with MRCP can obviously reduce the hospitalization costs,shorten the inhospital course,at the same time,can avoid increasing the incidence of misdiagnosis of CBD stones." @default.
