Understanding Gallbladder & Bile Duct Cancer
Gallbladder cancer (GBC) and cholangiocarcinoma (cancer of the bile ducts) are the two most common biliary tract malignancies. India has particularly high rates of GBC in certain regions — the Indo-Gangetic belt and Andhra Pradesh — likely related to cholelithiasis (gallstones) prevalence, Salmonella infection, and genetic factors. GBC is often discovered incidentally after cholecystectomy for “benign” gallstones.
Cholangiocarcinoma is classified by anatomical location: intrahepatic (within the liver), perihilar/Klatskin tumour (at the hepatic duct confluence — the most common, most complex), and distal cholangiocarcinoma (in the common bile duct). Each requires a different surgical strategy. Perihilar cholangiocarcinoma requires detailed biliary anatomy delineation with MRCP and hepatic volumetry before planning resection.
The only curative treatment for biliary tract cancers is surgical resection with clear margins. Unfortunately, most patients present with advanced or unresectable disease — emphasising the importance of specialist evaluation for every potentially operable case. Small tumours found incidentally (T1a GBC in the muscle layer) may be cured by cholecystectomy alone; T1b and T2+ require re-resection with liver bed excision and lymphadenectomy.
At a Glance
Symptoms of Gallbladder & Bile Duct Cancer
Biliary tract cancers are often diagnosed late — painless jaundice is the classic presentation and should always trigger urgent investigation.
Yellow skin/eyes from biliary obstruction — the most common presenting symptom.
Dull or colicky right upper abdominal pain, sometimes radiating to the back.
Significant unintentional weight loss and poor appetite.
Charcot’s triad (jaundice, fever, RUQ pain) suggests cholangitis — urgent treatment needed.
Raised tumour markers on routine blood tests — requires imaging investigation.

Surgical Treatment of Biliary Cancers
For gallbladder cancer, the extent of resection depends on T-stage. T1a: simple cholecystectomy is curative. T1b–T2: requires re-resection with a 2 cm margin of liver bed (segments IVb and V), portal lymphadenectomy, and bile duct resection if involved. T3–T4: more extensive hepatectomy with vascular reconstruction in selected cases. Patients who had laparoscopic cholecystectomy for GBC require re-staging and re-resection at a specialist centre.
For perihilar cholangiocarcinoma (Klatskin tumours), resection requires an extended hepatectomy (right or left), total bile duct excision, and biliary reconstruction with a Roux-en-Y hepaticojejunostomy. Pre-operative portal vein embolisation may be needed to ensure adequate future liver remnant. Bismuth-Corlette classification guides the extent of resection.
For distal cholangiocarcinoma, a Whipple’s procedure (pancreaticoduodenectomy) is performed. All biliary tract cancers benefit from adjuvant capecitabine chemotherapy after resection (BILCAP trial). FGFR2 inhibitors (for intrahepatic CC with FGFR2 fusions) and IDH1 inhibitors represent targeted therapy options in the palliative setting.
