PP, they did put a stent in. How did you guess? (The problem was an obstruction in the bile ducts, but I don't recall saying anything about that).
They had me in overnight before the op, which puzzled me. Didn't get much sleep though; they were in every two hours to take blood samples and blood pressure. First puzzle solved, but changed for another one; why wasn't one lot enough? Anyway, I was discharged and out at 8pm. Feel OK. Have yet to face Christmas dinner; that may be a test!
Thanks for your good wishes.
And Happy Christmas !
