Figure 1 Pancreatic duct stenting for preventing post-endoscopic retrograde cholangiopancreatography pancreatitis. A: Duodenal papilla before cannulation is performed; B: Duodenal papilledema occurs by frequent cannulation manipulation; C: Pancreatic duct stent is placed to regulate the passage of pancreatic juice.
