Comparitive Study On Hilar Cholangiocarcinoma On Msct With Surgical And Pathologic Findings

ObjectiveThere are no typical manifestations in the early stage of hilar cholangiocarcinoma. Most patients do not go to hospital until the advanced stage or late stage of disease. Hilar cholangiocarcinoma is still the sticky issue of surgical treatment. This study is to compare the CT findings, clinical and pathological character, to provide information for diagnose, treatment and prognosis, and to discuss the diagnostic value of MSCT in diagnosing hilar cholangiocarcinoma.Materials and Methods36 cases of hilar cholangiocarcinoma were examined with 16 slice CT scanner (GE lightspeed 16, USA, SIEMENS Sensation 16, Germany). All the cases were scanned with plain and dynamic contrast enhancement. The data were processed with workstation ADW4.2 or SIEMENS processing software. The diagnosis was conformed with surgical pathology.ResultsThe initial symptoms of hilar cholangiocarcinoma are intrahepatic cholangiectasis, mass of hepatic porta and narrow or absence of bile duct in the region of the hepatic porta. Most of mass shown delayed enhancement; 28 cases were high-differentiated gland cancer and eight cases were low-differentiated gland cancer in surgical pathology.ConclusionThe initial symptoms of hilar cholangiocarcinoma are obstructive jaundice, and the surgical treatment is the only effective method. MSCT plays an important role in qualitative analysis, determining the location and the surgical method. MSCT can show direct and indirect signs of hilar cholangiocarcinoma. But it also has limits in estimating infiltration of tumor.
