Preoperative diagnosis of biliary obstruction mainly depends on imaging examination.Percutaneous transhepatic cholangiography (PTC) is a common method in detecting biliary obstruction.PTC combined with computed tomography (CT) could enhance the diagnostic rate.From April 2009 to April 2011,8 patients with biliary obstruction were admitted to the Shenzhen Hospital of Peking University.Contrast solution (30 ml of iodine solution at a concentration of 1.5% -2.0%)was injected through a PTC tube,and then CT scan was performed.An iohexol contrast solution at a concentration of 300 mgl/ml was injected at a dosage of 1.5 ml/kg and at 3-5 ml/s,then the arterial phase,venous phase and delayed phase were scanned.The original data were uploaded to Vitrea 2 workstation for multiplane reconstruction,maximum intensity projection and volume rendering.The procedure was successfully performed on all patients,and the position of the biliary obstruction was identified in 7 patients.Five patients were diagnosed as with hilar cholangiocarcinoma,1 with sclerosing cholangitis and 2 with adenoma of the distal common bile duct.The patients' symptoms were alleviated after percutaneous transhepatic biliary drainage.
