Laughing through the pain with Ricky Gervais
I've learned more technical detail about the complications he experienced: hepatic artery stenosis and associated biliary stricture. In English, that means the hepatic artery (which is the primary supply of blood to the liver) collapsed, I think at the point where my piece of artery was sewn to his during the transplant. And then, as is frequently the case, that somehow caused the bile duct (which drains bile from the liver) to collapse, also at the point where mine was sewn to his. If you're feeling adventurous or if you're a scientific nerdy type, you might enjoy reading some of the many scientific articles published on the subject.
Joe's arterial stricture was solved with a stent, and a bile drain tube is currently propping open the bile duct. In both cases, Joe's tubes will heal and remain open independently. Then he's back on his way. And on to season two.
