A 46-year-old man was admitted to our hospital with abdominal pain. Abdominal ultrasonography and computed tomography (CT) showed a large pancreatic cyst in the pancreatic body. Magnetic resonance cholangiopancreatography suggested a large pancreatic pseudocyst. Endoscopic retrograde cholangiopancreatography revealed communication between the cyst lumen and the main pancreatic duct. Endoscopic nasopancreatic drainage was performed. Post-drainage CT revealed reduction in the size of the pancreatic cyst. Therefore, endoscopic pancreatic stenting was performed. The patient is being followed up and remains in good general condition. Two methods are available for endoscopic drainage of a pancreatic pseudocyst : transpapillary drainage and drainage guided by endosonography through the stomach or the duodenum. Drainage guided by endosonography is impossible without a specific modality and devices, as it carries a high risk of hemorrhage and perforation. The indication for transpapillary drainage is a cyst in communication with the pancreatic duct. It is a less invasive and safer procedure.
