<s>[INST] I had an ultrasound in Nov that showed that I had several stomes/polyps lagest one 5mm.  Repeated ultrasound in March & showed several polyps largest one 8mm.  Makes me wonder if that 5mm grew that quick or measurements not correct.  Considering removing gallblader but unsure. [/INST] Hi, dairy have gone through your question. I can understand your concern. You have multiple polyps in gall bladder. Largest was 5 mm in November and now its 8 mm. It may be slightly increased and 1 to 2 mm variation is common so it's not a big difference. Whether it is 5 mm or 8 mm it doesn't make any difference in treatment. You should go for cholecystectomy. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
