Pancreatic pseudocyst is one of the complications of pancreatitis, and its recurrent symptoms have a significant impact on the quality of life of patients. At present, the treatment methods for pancreatic pseudocysts include surgical treatment, percutaneous puncture drainage, and endoscopic natural cavity drainage. In recent years, endoscopic natural lumen drainage has gradually become a standard treatment method, mainly guided by endoscopic ultrasonography (EUS) to establish an effective drainage channel between the cyst and the stomach or duodenum, in order to achieve internal drainage of the cyst. In clinical practice, various forms of stents are usually placed between channels to ensure their good open state.
