The surgical procedure starts by opening the abdomen with an incision (usually shaped like an “L”). The sick liver and the gallbladder are removed, then the new liver is ‘implanted’, which means that it is put in the abdomen in place of the old liver, and connected to the blood vessels. Typically, in liver transplants, the common bile duct from the donor is joined to the recipient common bile duct. In PSC transplants, this doesn’t usually happen because the old bile duct still has the potential to have PSC and so the surgeons don’t usually create a normal anastomosis (join). In PSC, the existing bile duct is removed, and something called a Roux loop (Roux en Y) is formed.
