Describe and explain the consequences of a gallstone that becomes stuck in the bile duct, either above or below the site where the pancreatic duct joins the bile duct.
What will be an ideal response?
Ans: A gallstone blocking the bile duct (only) will prevent or reduce secretion of bile salts into the intestine. This will interfere with fat digestion and absorption (causing weight loss, as well as diarrhea due to the fat being metabolized by bacteria in the large intestine), as well as interfering with the absorption of fat soluble vitamins (A, D, E and K), leading to problems such as poor clotting, poor calcium absorption, poor vision or skin. A bilirubin is not released, it will build up in the blood, giving a yellow appearance to the skin (jaundice). A gallstone lodged where it blocks both the bile duct and the pancreatic duct will, additionally, block all the digestive enzymes from the pancreas, resulting in poor digestion of all foods, leading to weight loss and diarrhea.
