Overview

Cholangiocarcinoma must be differentiated from other diseases that cause jaundice, abdominal pain, weight loss, and fatigue, such as gallbladder cancer, hepatocellular carcinoma, pancreatic cancer, cholecystitis, and choledochitis.

Differentiating cholangiocarcinoma from other diseases

Cholangiocarcinoma must be differentiated from other diseases that cause jaundice, abdominal pain, weight loss, and fever such as Gallbladder cancer, hepatocellular carcinoma, pancreatic cancer, cholecystitis, choledochitis and liver fluke infections.
