The best Viking Age example is the two sided game board from the Gokstad ship (c. 900). This is clearly Nine Men's Morris with its three courts. There is also what is clearly a Nine Men's Morris board on slate found at Peel, on the Isle of Man.
Jaundice is the most common symptom of bile duct cancer, but most cases of jaundice are not caused by cancer. Jaundice is more often caused by hepatitis (inflammation of the liver) or a gallstone that has traveled to the bile duct. But whenever jaundice occurs, a doctor should be seen right away.
Bile is also stored in the gallbladder. If the bile duct becomes blocked, the bile cannot drain normally and backs up in the liver. Signs of blocked bile ducts include jaundice (yellowing of the skin), dark urine, light stools, itching, nausea and poor appetite. This is a potentially serious condition that needs to be treated. It is possible to relieve the obstruction by inserting a fine plastic drainage tube (catheter) through the skin (percutaneous) into the obstructed bile duct, past the obstruction and into the duodenum.
