Biliary colic occurs when a gallstone becomes lodged in the cystic duct and the gallbladder contracts against the obstruction, in response to a fatty meal. Complications include acute cholecystitis, pancreatitis, and ascending cholangitis. A RUQ ultrasound is the diagnostic test of choice due to its high sensitivity and specificity. Cholecystectomy is recommended. Dissolution therapies (eg, ursodiol) are reserved for nonsurgical candidates.
