Pancreatic duct stones are secondary to chronic pancreatitis while conventional medical treatment is always not effective. Due to the advantages of less trauma, simple operation, and fewer complications, since endoscopic retrograde cholangiopancreatography (ERCP) combined with extracorporeal shock wave lithotripsy (ESWL) was first used in the treatment of pancreatic duct stones in 1987, the treatment method has been continuously improved for more than 30 years, and has experienced the development process from being questioned to becoming the first-line treatment for pancreatic duct stones in multinational guidelines nowadays. However, with the rapid development of science and technology today, the method of ERCP combined with extracorporeal lithotripsy is also facing the challenges of many other treatment methods.
