Periampullary Clot Causing Biliary Obstruction: A Rare Presentation

Acute cholangitis is an emergency condition that requires an emergency biliary drainage for source control of the infection. Commonly cholangitis is precipitated by biliary obstruction due to causes like stones, strictures, stents, or malignancy of the pancreaticobiliary or ampullary origin. We report a unique case of a man who had acute cholangitis due to a periampullary clot who was fully recovered after clot removal by endoscopic retrograde cholangiopancreatography (ERCP).
