The pancreas is a retroperitoneal organ, and the accuracy of traditional imaging in the diagnosis of pancreatic diseases is not high. When a malignant tumor is found, it is often in an advanced stage and the patient loses the opportunity for surgery. Endoscopic ultrasound guided fine needle biopsy has high diagnostic value for pancreatic diseases and is widely used in the diagnosis of pancreatic diseases. Some emerging ultrasound endoscopic imaging techniques, such as elastography and confocal laser endoscopy, have also become important diagnostic tools. Endoscopic drainage under ultrasound guidance is the preferred method for intrapancreatic drainage. Ultrasound-guided radiofrequency ablation, as a new therapeutic approach, is also beginning to play an important role in neoadjuvant and palliative care for pancreatic cancer. The development and popularization of endoscopic ultrasound will provide a new way for the diagnosis and treatment of solid pancreatic diseases.
