Main pancreatic duct: morphlogy after acute biliary pancreatitis with magnetic resonance cholangiopancreatography after secretin stimulation.

Objective: to assess whether a magnetic resonance cholangiopancreatography performed after an acute biliary pancreatitis leads to pancreatic morphological alterations and if secretin stimulation influences the visualization of the pancreatic tree.

Method: forty patients with acute biliary pancreatitis, 25 female (62,5/) and 15 male (37,5/), 27 mild and 13 severe, were prospectively and consecutively studied. All patients had undergone cholecystectomy.
