Giant Staghorn Common Bile Duct Calculus (A Case Report)

Giant staghorn common bile duct (CBD) calculi are usually uncommon but can be found in patients with oriental cholangiohepatitis. The size of stone can vary from few millimetres to several centimetres. These are usually pigment stones and patients can present with pain, jaundice and fever or some times Reynold's pentad. Primary bile duct stones form within the bile ducts and usually are of brown pigment variety containing higher proportion of bilirubin as compared to cholesterol. Bile infection appears to be the initial event leading to stone formation. The secondary CBD stones arise from gall bladder or intra and extrahepatic ducts. They are mostly cholesterol stones. We are presenting a case in which we removed a giant staghorn calculus from the CBD measuring 11.5 × 4 cm and weighing about 100 g.
