Mandatory medical device diagnostics.
- Abdominal ultrasonography (ultrasonography of abdominal organs) [safe detection of cholestasis (biliary obstruction) as the most common complication of biliary tumors]
- Esophago-gastro-duodenoscopy (ÖGD; reflection of esophagus, stomach and duodenum).
- Endosonography (endoscopic ultrasound (EUS); ultrasound examination performed from the inside, i.e., the ultrasound probe is brought into direct contact with the internal surface (for example, the mucosa of the stomach/intestine) by means of an endoscope (optical instrument)). – To detect tumors in the orifice of the duodenum (duodenum).
- Intraductal sonography – ultrasound with miniaturized probe (image center) in dilated bile duct; for staging; the method allows a good statement about the local tumor extent including involvement of regional lymph nodes (especially in distal bile duct tumors).
- Endoscopic retrograde cholangiopancreaticography (ERCP) – X-ray imaging of the bile duct system and ductus pancreaticus during an endoscopic examination; possibility of biopsy (tissue sampling) and therapy: in inoperable tumors in the bile duct area, a stent can be inserted to restore the passage of bile.
Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics and obligatory medical device diagnostics – for differential diagnostic clarification.
- Magnetic resonance imaging of the abdomen (abdominal MRI).
- Computed tomography (CT) of the abdomen (abdominal CT) – for staging.
