Clinical manifestations of common bile duct obstruction include all of the following except?

Explanation:
Obstruction of the common bile duct causes cholestasis, so bile cannot reach the intestine. This leads to bile pigments building up in the blood and being excreted by the kidneys. Clinically, you see pale or clay-colored stools because bilirubin pigments aren’t reaching the gut, jaundice from elevated bilirubin in the blood, and pruritus from bile acids deposited in the skin. Urine becomes dark because conjugated bilirubin is excreted in the urine. Light-colored urine would not be expected in this situation; instead, urine is dark. Therefore, light-colored urine is the exception among the listed manifestations.
