[Gastrointestinal hemorrhage into the duct of Wirsung caused by chronic pancreatitis and carcinoma of the pancreas (author's transl)].

Report on 3 cases of gastrointestinal bleeding from the pancreas. In 2 patients with pancreatic pseudocysts and carcinoma of the pancreas a hemorrhage from the papilla Vateri due to a communication with the common pancreatic duct was observed endoscopically. In the third case a pancreatic pseudocyst had ruptured into the stomach. In the 2 cases with bleeding from the papilla routine gastroscopy with prograde optical fiberscope revealed blood in the duodenum, while the cause of bleeding could be established only with a side viewing duodenoscope.
