<s>[INST] can anyone explain how someone can be diagnosed with multiple gallstones and gallbladder polyps, to be told 6months later polyps have gone and one gallstone can be seen. Gallbladder [/INST] Hi. You haven't mentioned the number of stones and range of their size. Similarly, you have also not mentioned the details of polyps. Anyway.1. The key investigation for the diagnosis of both is ultrasound scan.2. The disappearance of stones without having caused any symptoms (particularly severe pain) and spontaneous disappearance of polyps is unusual. 3. I would recommend you to repeat ultrasound scan from another experienced monologist. I do not mean to doubt competency of your previous monologist, but that's the best suggestion I can offer because of the fact discussed above (point number 2). Thanks. </s>
