Guideline for the Management of Bile Duct Cancer by the Brazilian Gastrointestinal Tumor Group

This is a clinical practice guideline for patients with biliary tract cancers, including gallbladder cancer, intrahepatic and extrahepatic cholangiocarcinoma, and cancer of the duodenal papilla. The guideline examines the diagnosis, staging, and treatment of these patients. Tests discussed for the diagnosis and staging include endoscopic retrograde cholangiopancreatography (ERCP), upper GI endoscopy (UGIE), endoscopic ultrasound (EUS), cholangioscopy, and laparoscopy. Surgical options are stratified by disease type, and both adjuvant treatment and systemic treatment for metastatic cancer of the biliary tract are also discussed.
