Accurate diagnosis and staging of cholangiocarcinoma are now possible using imaging and cholangiography. Surgical resection is feasible for localized tumors, while unresectable cases require palliative care and tissue diagnosis.

Area of Science:

Hepatobiliary Surgery
Surgical Oncology
Diagnostic Imaging

Background:

Cholangiocarcinoma diagnosis has improved in accuracy and speed.
Obstructive jaundice presentation often involves dilated intrahepatic ducts.

Purpose of the Study:

To outline current diagnostic and staging methods for cholangiocarcinoma.
To discuss surgical resectability criteria and treatment options.
To review the role of adjuvant therapies.

Main Methods:

Diagnosis confirmed by cholangiography.
Tumor staging via cholangiography and angiography.
Assessment of tumor involvement of liver lobes and major vessels.

Main Results:

Related Experiment Videos

Unresectable if tumor involves both liver lobes or main portal vein/hepatic artery.
Resectable if tumor is distal to hepatic duct bifurcation or involves one lobe/vessel.
Up to 50% of explored patients achieve successful resection.

Conclusions:

Surgical options vary based on tumor site and extent.
Radiotherapy's role in cholangiocarcinoma management requires further study.
Adjuvant chemotherapy and hormonal therapy need further investigation for survival improvement.
