Abdominal ultrasound showed the classic presentation of the Wall-Echo-Shadow (WES) sign. The superficial aspect of the gallbladder wall is represented by a hyperechogenic curve. Below this, bile fluid is represented by hypoechogenicity. Underneath the bile fluid is the echo of the dense border created by the collection of gallstones, represented by a hyperechogenic curve. Due to the high density of the gallstones, nothing deeper can be visualized (including other gallstones or the far end of the gallbladder); this is the shadow.

At the end of this simulation session, the learner will: 1) Recognize signs and symptoms of mesenteric ischemia; 2) order appropriately imaging and labs in the workup of an elderly patient with abdominal pain; 3) manage a patient with mesenteric ischemia, a rare, but serious cause of abdominal pain in the elderly; 4) discuss anchoring bias, specifically related to patients referred to the ED with an established diagnosis by outside specialists.
