I have been having this issue for three years now.  It first started in 2010 when I had a gallbladder attack and they removed my gallbladder.  Ever since then, I have these random episodes.  It starts with bloating and burps that smell like fart.  Then I will start vomiting up what seems like fecal matter mixed with undigested food if Ive eaten anything recently.  Once the vomiting stops I will have diarrhea that looks and smells exactly like the vomit.  Then the process repeats itself from a few hours up to a few days.  During the entire episode I have extreme abdominal pain.  The doctors have prescribed phenegran for the n/v but it does nothing to stop it or even help at all.  Ive had 4 endoscopes done, 1 flex sig, and 3 full colonoscopys all after (not during) an episode, and they all have come up with no answers.  They found diverticuli in my colon along with polyps (negative results on those), but they said those wouldnt be causing these issues.  Ive had multiple x-rays, ct scans, have drank every nasty mix of stuff before the scans they can think of, and still cant get any answers or a direction as to what it might be.
Hi.thanks for posting query at Chat Doctor. Read your question thoroughly and understood your concern. Gall bladder primary role is to store \"bile\".when gall bladder is intact, bile is usually secreted after having a meal rich in fat; bile plays a vital role in fat digestion. After gall bladder is removed, bile is continuously being secreted in small intestine and may reflux into stomach. As a result, gastric inflammation may occur causing pain and discomfort. Moreover, high fat meal induces more bile synthesis - further affecting gastric mucosa as well as bile is less concentrated and Chat Doctor. Advise
