The majority (70 %) of patients with severe chronic pancreatitis who respond to pancreatic stenting maintain this response after definitive stent removal. However, a significantly higher re-stenting rate was observed in patients with chronic pancreatitis and pancreas divisum.

Wirsungorrhagy can be responsible for massive bleeding in certain patients, especially those with chronic pancreatitis and pseudoaneurysm. In these cases, arteriography is most useful for identification and treatment of the bleeding. When it occurs during endoscopic manipulations, it can usually be managed endoscopically and/or stops spontaneously with appropriate main pancreatic duct drainage. When it occurs in patients with pancreatic tumors, optimal treatment is surgical resection; this is, unfortunately, usually not feasible.
