Abstract:
Objective To explore the diagnostic value of contrast-enhanced spiral CT after low tension and drinking water in papillary carcinoma of ampulla. Methods CT manifestations of papillary carcinoma of ampulla comfirmed pathologically in 20 cases were analysed retrospectively emphasized in artery phase on contrast CT which was performed after injecting 654-2 20 mg and drinking 300~500 ml water.Results Of all the cases , only 2 cases showed tumor filling defect in the descending part of duedenum nearby pancreas on routine CT, but all the cases showed more or less tumor filling defect on contrast-enhanced spiral CT . The diameters of the tumor were between 0.8 to 2.6 cm,2 cases with head of pancreas affected,the diameters of the tumor were between 2.4 to 2.6 cm.There were 2 cases with lymph node metastasis nearby duedenum.All the cases showed expansion of gallbladder ,intrahepatic duct and choledochus expanding in the liver. Conclusion Contrast-enhanced spiral CT after low tension and drinking water is superior to routine CT in determining the size and morphosis of tumor.
