Surgical treatment for hilar cholangiocarcinoma of Bismuth-Corlette type IV

Abstract

To investigate the surgical treatment for hilar cholangiocarcinoma(HCCA) of Bismuth-Corlette type IV. The clinical data of 73 HCCA patients admitted in Southwest Hospital, the Third Military Medical University from January 2002 to December 2008 were analyzed retrospectively. There were 41 males and 32 females, aged from 30 to 84 years old (averaged, 56.8 years old). All patients were diagnosed as hilar mass with hilar biliary obstruction by B-ultrasound, CT, magnetic resonance imaging, endoscopic retrograde cholangiopancreatography, magnetic resonance cholangiopancreatography or percutaneous transhepatic cholangiography, and confirmed by pathological examination in intra-operation and post-operation. Diagnosis of all patients were according to Bismuth-Corlette type IV. Fifteen cases underwent percutaneous transhepatic cholangial drainage, stents were implanted in 8 patients. Simple internal drainage was performed on 25 of the 73 patients and 4 with palliative resection. Radical resection was performed on 19 patients. The radical resection rate of HCCA were 26.0%. The 1, 3 years of survival rates were 36.8%, 10.5% respectively. The 1 year survival rate was 6.3% in drainage group. Radical resection is the potentially curative treatment for HCCA, a sufficient, reasonable use of internal and external drainage would improve the patient's quality of life.
