<s>[INST] Hi, My name is Ammy, I am from Canada I am having upper abdominal pain from last two months. My went through so many tests like breath test , abdominal ultrasound, flouroscopy and now my family doctor is gonna send me for CT scan . I don t know what s going on , I am just wondering if any GI can help me to get rid of this pain. I have previous history of gall bladder removal, after gall bladder removal I still had pain for one year, then I got very bad pancreatitis , next to it doctors in India found through ultrasound that there was a stone in the cystic duct, it was removed in Dec 2009 by surgery . I did not have any pain since Dec 2009, but now again I am having upper abdominal pain, bloating, chest pressure &pain and also back pain between the shoulder bladdes. Pain in the upper abdomen stops when I eat something. I would be highly grateful if someone can help me. [/INST] Hello! This might be either gastric ulcer or some blockage in biliary/pancreatic tract. And either way gastrostomy with ERCP should be performed as soon as possible (it will rule out both). Before it, you should have blood tests with hepatic and pancreatic enzymes done. CT scan is necessary if acute pancreas inflammation will be recognized or when gastrostomy/ERCP will show nothing. Until this test you should keep hepatic diet. Hope this will help </s>
