A rare case of acute cholangitis after endoscopic ampullectomy.

Endoscopic ampullectomy is indicated for the resection of non-invasive papillary adenomas in selected patients. Cholangitis is an uncommon complication (0-2%) that may be secondary to contamination during the procedure, poor emptying of the bile duct and prosthesis dysfunction or migration. Placement of a prophylactic biliary stent after the resection is not well established. We present a rare case of acute cholangitis after endoscopic ampullectomy secondary to a biliary prosthesis obstruction, due to a pancreatic prosthesis intrusion.
