Abstract: With a high degree of malignancy, pancreatic adenocarcinoma is a difficulty in clinical work. Multislice spiral CT, magnetic resonance imaging (MRI) and endoscopic ultrasound (EUS) are important diagnostic methods for pancreatic adenocarcinoma. With the continuous improvement of EUS technology, the value of EUS technique in diagnosis of pancreatic adenocarcinoma is gradually increased, especially EUS-guided fine needle aspiration (EUS-FNA), an important method for pancreatic biopsy. In addition, EUS also plays a key role in the treatment of pancreatic adenocarcinoma. EUS elastography (EUSEG) and contrast-enhanced EUS (CE-EUS) can guide clinical administration of medication. EUS-guided therapy is also an important component in comprehensive treatment of pancreatic adenocarcinoma. Therefore, we reviewed and evaluated the role of EUS in the diagnosis and treatment of pancreatic adenocarcinoma.
