Diagnosis B l o o d T e s t s – T u m o u r M a r k e r s CA 19-9 • Increase in 50 – 70% of patients with biliary tract cancer CEA • Increase in 40 - 70% of patients with biliary tract cancer No specific and sensitive tumour markers for biliary tract cancer are available Improved diagnostic ability can be achieved with a combination of tumour markers and other imaging Patel AH, Harnois DM, Klee GG, at al.

Resectability W h a t a r e t h e u n r e s e c t a b l e f a c t o r s ? Poor General condition: • Major surgery is often needed • Functions of liver, heart, lung, kidney and performance status Presence of metastasis (liver, lung, peritoneum, distant lymph nodes): • Lymph node in hepatoduodenal ligament (N1): resectable • Peripancreatic lymph node (N2): unresectable • Para-aortic and exptraperitoneal lymph nodes (Distant): unresectable Weber SM, DeMatteo RP, Fong Y, Blumgart LH, Jarnagin WR.Staging laparoscopy inpatients with extrahepatic biliary carcinoma: analysis of 100 patients.

Resectability W h a t a r e t h e u n r e s e c t a b l e f a c t o r s ? Local extension of tumour: • Encasement or occlusion of main portal vein • Tumour extension to secondary biliary branches bilaterally • More aggressive surgical approaches like resection and reconstruction of the portal vein and/or hepatic artery have been reported Jarnagin WR, Fong Y, DeMatteo RP, Gonen M, Burke EC, Bodniewicz BS J, et al.

Assessment of Liver Function GOOD NO GOOD
Assessment of Liver Function A n y e f f e c t i v e m e a s u r e ? • Liver failure is the main cause of mortality • The perioperative outcome of hepatic resection has improved remarkably in recent years with improved surgical techniques and perioperative care • As a result, the indications of hepatic resection have been extended to include patients with borderline liver function
Assessment of Liver Function C T V o l u m e t r y CT Volumetry: • Measuring the ratio of the future remnant liver volume to the total liver volume • To assess effect of portal vein embolization • Percentage of residual liver volume around 40-50% should be safe in cirrhotic liver • 25% in normal liver Lee SG, Hwang S.

Assessment of Liver Function I C G c l e a r a n c e t e s t Indocyanine green (ICG) clearance test: • Generally used in pre-operative assessment of hepatic function reserve • Widely recognized as a predictor for post-operative death and the development of liver failure in patients with liver cirrhosis • Occurrence of cholangitis prior to resection have unfavourable impacts on post-operative results even in patients with good hepatic functional reserve Miyagawa S, Makuuchi M, Kawasaki S, Kakazu T.

Guidelines for the management of biliary tract and ampullary carcinomas: surgical treatment. J Hepatobiliary Pancreat Surg. 2008;15(1):41-54.

Pre-operative biliary drainage I s I t n e c e s s a r y ? Pre-operative biliary drainage is recommended for patients with cholangitis or patients scheduled to undergo extended hepatectomy
Pre-operative biliary drainage H o w ? • No RCTs compared percutaneous and endoscopic drainage as the most appropriate pre-operative drainage method in cholangiocarcinoma • Two RCTs on stent therapy for unresectable cases • Endoscopic procedure was superior to percutaneous stents and bypass surgery • For hilar lesion, endoscopic drainage is often difficult • Percutaneous drainage may be more effective and recommended Speer AG, Cotton PB, Russell RC, et al.

Pre-operative biliary drainage W h a t p r o c e d u r e s a r e a p p r o p r I a t e ? Percutaneous transhepatic or endoscopic, drainage can be used. The method that can be safely performed with the equipment and techniques available at each facility.
