Endoscopic Ultrasound Staging
Preoperative staging of pancreatic cancer determines the therapeutic approach to the malignancy. The major decision point is whether surgical resection will be attempted or nonoperative therapy will be employed. Cross sectional imaging is often used to initially localize the primary site of a pancreatic malignancy. Although staging of the pancreatic malignancy can be assessed with diagnostic CT and MRI scanning, detailed staging is usually performed with specific staging protocols that involve the use of timed administration of intravenous contrast agents. Endoscopic ultrasound (EUS) uses high frequency ultrasound images to provide detailed imaging of the primary malignancy and its relationship to adjacent structures, such as the portal venous system. With accurate staging, inappropriate therapy, such as unsuccessful surgical resection can be avoided and palliative therapy can be provided to patients with advanced disease.
