Could a colonoscopy or endoscopy allow the doctor to see the pancreas?

Only the duct system: Scopes are inside the intestines. The pancreas is external to the intestines. The opening of the duct leading from the pancreas into the intestines is visible. The endoscopist can enter that duct and inject a dye that will light up the ducts within the pancreas. This procedure can identify problems within the pancreatic duct system.
