Hi, My wife is recently diagnosed with pancreatic and gall bladder stone. We did ultra sound twice a few months back and the stone size as reported in gall bladder was 8 mm and small size stones in pancreas. However, we did ultrasound in the same clinic a day back and the report says that pancreas has 18mm stone and gall bladder has small size stones. Is this possible that in a month’s time pancreas stone increases that big in size and how critical this is? should we go for other alternative ultrasound?
