Successful treatment of an impacted lithotripter basket in the common bile duct with intracorporeal electrohydraulic lithotripsy.

A 62-year-old woman with hypothyroidism and hypertension presented to an outside hospital with abdominal pain. She was found on her initial workup to have choledocholithiasis and was transferred to our institution for endoscopic retrograde cholangiopancreatography (ERCP).
