Y1 - 2021 N1 - T2 - Ma and Mateer's Emergency Ultrasound, 4e AB - Abdominal pain is the most common chief complaint in patients presenting to the emergency department (ED), accounting for more than 12 million visits annually in the United States.1 An estimated 15% of the U.S. population has gallstones with 1–4% becoming symptomatic per year, of whom 20% will develop acute cholecystitis.2–4 This disease burden results in over 200,000 hospitalizations each year for acute cholecystitis.5 Point-of-care ultrasound (POCUS) has been used to both diagnose and exclude gallstone-related pathology with a high degree of confidence, resulting in improved clinical decision-making and ED throughput.6–9 Emergency physicians who perform POCUS proficiently can impact the care of patients presenting with abdominal pain.
