vasoactive-intestinal-peptide and Pancreatic-Cyst

A 32-year old patient presented with recurrent pancreatitis, severe watery diarrhea and elevated serum levels of vasoactive intestinal polypeptide. His diarrhea appeared to respond to intramuscular propantheline. Initially he improved but had another attack of pancreatitis while hospitalized. Evaluation by ultrasound revealed the presence of a pseudocyst and endoscopic retrograde pancreatography demonstrated complete occlusion of the main pancreatic duct. Exploratory laparotomy was performed with drainage of a pseudocyst. Analysis of the pseudocyst fluid revealed an elevated amylase, lipase and vasoactive intestinal polypeptide level. It is believed that this patient's severe diarrhea was related to his pancreatitis and pancreatic pseudocyst with elevated levels of vasoactive intestinal polypeptide.
