Mechanical intestinal obstruction from pseudocyst bezoar following internal drainage of traumatic pancreatic pseudocyst.

A unique case of intraluminal mechanical small-intestinal obstruction occurring from a bezoar of organized debris that extruded from a post-traumatic pancreatic pseudocyst following Roux-en-Y cystojejunostomy is presented. Although an apparently unusual complication, it is one that should be considered in any patient experiencing incomplete cyst drainage or intestinal obstruction following an internal drainage procedure for pancreatic pseudocyst.
