An elderly woman with a history of choledocholithiasis presented to the emergency department with a 3-day history of nausea and abdominal pain. She was admitted to the general internal medicine (GIM) service with a diagnosis of recurrent biliary obstruction due to microlithiasis. She underwent an endoscopic retrograde cholangiopancreatogram (ERCP) 2 days later (on a Friday), which was unsuccessful at cannulizing the common bile duct. Plans were made for a percutaneous biliary drain insertion and rendezvous ERCP (an interventional radiology technique to increase the success of an ERCP procedure) for the following Monday.
