My 69 yr old brother has been having blood in his bowels, he passes out, goes to Er, they have ran MRI, 3 colonoscopys He has lost a lot of blood and would have to have blood and plasma given to him as much as 3 - 5 bags. A lot, ugh? This has been going on since Sept. They did clip a blood vessel in his stomach that was just laying on the lining of his stomach. They have ran other tests but cannot find where he is still bleeding or why? Canadaquia NY Hospital and also Rochester NY hospital. What do you conclude It might be?
