Tests to Surrounding Organs 
• Upper gastrointestinal tract x-rays (UGI series) may be done to examine the duodenum (the portion of the
  small intestine that surrounds the pancreas) to look for abnormalities.
• A needle may be inserted into the liver to discover obstructions in the bile duct (percutaneous transhepatic
  cholangiogram).
•  Liver biopsy to confirm metastases, if suspected.
  Ninety percent of cases can be diagnosed with abdominal ultrasound , CT scans, ERCP and a positive CA
  19-9, although early diagnosis remains difficult.
