Overall, 39% of these cases required admission and 80% were diagnosed with acute gallbladder and bile duct-related conditions such as cholecystitis. When the emergency physician diagnosed gallstones without acute inflammatory conditions, 88% of cases were discharged from the ED.2 Consequently, emergency physicians who can effectively perform point-of-care ultrasound have the potential to efficiently impact the care of patients with right upper quadrant abdominal pain.
