Paak…..I am sorry to hear of the latest developments. In regards to the elevated ammonia levels, have the physicians mentioned hepatic encephalopathy? This can be treated with lactulose. Our Percy had posted the following: http://www.cholangiocarcinoma.org/punbb/viewtopic.php?id=6004
GI bleeds also are not uncommon; most (but not all) are caused by Esophageal varices which develop when normal blood flow to your liver is slowed. This causes the blood to back up into smaller blood vessels. Banding of these varicies has been helpful for some.
As always, dear Paak, all information on this site needs to be confirmed by a physician.
Hopefully others will come forward and share some of their thoughts with you also. Hang in there.
A tidal wave of good wishes are heading your way,
Hugs,
Marion
