Courvoisier's law revisited.

According to Courvoisier's law; if gallbladder is palpable in a jaundiced patient, it is unlikely to be due to gallstones, because stones would have given rise to chronic inflammation and subsequently fibrosis of gallbladder therefore, rendering it incapable of dilatation. Conversely, the causes other than stone (principally tumours), would result in the distension of gallbladder, felt on abdominal palpation. However, in Courvoisier study of 109 cases of dilatation of gallbladder, 17 were due to impacted stones. Therefore, Courvoisier concluded that dilatation of gallbladder was rare with stones obstructing the common bile duct. Despite this fact it is always assumed that the palpable gallbladder is due to malignancy (pancreatic or periampullary etc.). Here, we report a rare case of palpable gallbladder in a jaundiced patient due to multiple cholelithiasis and a large choledocholithiasis causing obstruction of CBD.
