Each type of diagnostic information can be provided in phases, thus reducing the number of exploratory laparotomy and an increase in the proportion of patients undergoing surgery.

Of these CT, ultrasound, or ERCP examination, that surgery patients have to accept some of the other inspection methods can provide additional staging information. Researchers have proposed to use laparoscopy for staging of pancreatic cancer.

The CT examination and combination of pre-operative angiography can periampullary tumor patients in phases. Large vessels have been wrapped or blocked, significantly reduced the possibility of surgery, while patients with normal angiography most likely to surgical resection. The importance of pre-operative angiography, which shows the abnormal blood vessels on the abdomen, which is usually associated with superior mesenteric artery from the right hepatic artery anomalies related, 16% ~ 29% of patients may occur such a change. Because the blood vessels through the head of pancreas, liver, arterial blood loss and extrahepatic bile leakage is dangerous.

Tumor marker does not help the diagnosis or staging of pancreatic cancer, but further treatment may play a role, carcinoembryonic antigen (CEA) is elevated in many patients, but the sensitivity is low, some other benign and malignant tumors patients are also rising. CA19-9 than CEA is more useful for the diagnosis of pancreatic cancer, but pancreatic cancer is not a specific, colon and bile duct cancer patients can also be increased. Other tumor markers, such as the DU-PAN-2-pancreatic cancer antigen, and galactosyltransferase isoenzyme, did not have a universal effect, but also not readily available.
