Cholelithiasis refers to gallstone formation anywhere along the biliary tree. Gallstones are present in up to 10% of the population, and only about 1/4 of patients are symptomatic. When symptomatic, the most common finding is biliary colic (post-prandial RUQ pain, especially following a fat-rich meal). Pain may radiate to tip of the right scapula, a finding known as Collin’s sign. Nausea, bloating, belching, heartburn, and flatulence are also common (Bell).
