Both the differential diagnosis of pancreatobiliary malignancies and the confirm diagnose of pancreatic carcinoma are the key points for the clinical treatment of pancreatobiliary diseases. A better understanding of the aetiology and pathology and an appropriate choose of diagnostic methods are very helpful for the diagnosis and treatment of pancreatobiliary malignancies.
