Biliary System

This lady was admitted with a 4 day history of severe upper abdominal pain. She was tender in the right upper quadrant with a positive Murphy's sign. An ultrasound of the right upper quadrant confirmed the clinical suspicion of symptomatic cholelithiasis. There was ultrasonographic evidence of a thickened gall bladder wall with a single large gallstone seen impacted in Hartman's pouch.
She was initially treated conservatively, but then had to undergo an emergency laparotomy.
