Application of endoscopic ultrasound interventional therapy in biliary and pancreatic diseases

Endoscopic ultrasound (EUS) has been greatly developed in the diagnosis of digestive diseases. In recent years, with the continuous innovation of endoscopic technology and accessories, important breakthroughs have been made in endoscopic ultrasound-guided interventional therapy, especially in the treatment of refractory biliary and pancreatic diseases. Based on the latest literatures and work experience, in this paper, we reviewed the latest progress of EUS interventional treatment for biliary and pancreatic diseases, including EUS- guided bile duct drainage, EUS-guided gallbladder drainage, EUS-guided pancreatic duct drainage, EUS guided-pancreatic pseudocyst drainage, and EUS guided pancreatic tumor treatment.
