Choledocholithiasis is the most common non-neoplastic cause of biliary obstruction, accounting for 14% of all new cases of jaundice.2 An estimated 20 million Americans have gallstones, and risk factors for choledocholithiasis include female sex, older age, increasing body mass index, and rapid weight loss.22, Gallstones may cause jaundice by obstructing the biliary tree (typically the common bile duct) or by inducing a biliary stricture.23 Less commonly, stones in the gallbladder or cystic duct may mechanically compress the common hepatic duct causing jaundice, and, rarely, stones may cause the formation of a biliary-vascular fistula with accompanying jaundice.24 Biliary stricture causing postoperative jaundice is a rare complication of cholecystectomy (0.6% of cases).7,23, Jaundice may be caused by surgeries such as liver transplantation and the Whipple and Billroth procedures, which both involve the creation of a choledochojejunostomy.

The initial laboratory evaluation of jaundice in adults should include fractionated bilirubin, complete blood count, alanine transaminase, aspartate transaminase, alkaline phosphatase, -glutamyltransferase, prothrombin time and/or international normalized ratio, albumin, and protein.
