Figure 7.
Main pancreatic duct leak 53-year-old man with multiple bouts of acute pancreatitis. A stricture of the main pancreatic duct (short arrows) is seen on MRCP before secretin administration (A). At 1 minute after secretin administration (B), fluid accumulates in the stomach, consistent with a pancreaticogastric fistula. Fluid progresses into the duodenum at 2 minutes (C) and 5 minutes (D). The downstream main pancreatic duct does not dilate (curved arrow) given flow of pancreatic fluid through the fistula.
