Excess bile, excruciating pain after gall bladder surgery

Hi
I'm desperately trying to find some help regarding my husband's excruciating chronic stomach pain since his gall bladder removal. He has excess bile constantly in his stomach diagnosed by colonoscopies, gastro emptying studies, and other tests but so far all medicines and tests have not helped him. Nor has changing his diet and he doesn't want to go on any more. I don't know where to turn for help and I was hoping that maybe a doctor online would be able to point me in a direction as to other tests or possible ways to aleviate his pain so he finds life worth living again. I'm not really great on the computer but I would certainly be extremely grateful for any help that you could give me. My husband is barely 50 and he has been suffering now for over three years with absolutely no day or night free of pain. Which has resulted in an addiction to sleep medications and gastritis as he has tried to relieve his excruciating pain. If you can give me any help I would so appreciate it because things are desperate here. Thank you.
