Endoscopic basket impaction.

Endoscopic Retrograde Cholangiopancreatography (ERCP) is an indispensable tool for imaging the pancreatico-biliary tree, and in treating diseases of the pancreatic and biliary systems. ERCP plays a primary role in the management of choledocholithiasis, both in diagnosis and treatment. Complications occur infrequently and can usually be treated nonoperatively. An unusual complication of ERCP and an impacted stone retrieval basket are presented and discussed along with review of the medical literature.
