There is no fixed rule for how big gallbladder stones are in general. Small ones may be just a few millimeters, large ones may reach more than 3cm, and conventional ones may still be between 1-2cm, although there is a certain range, but there is no definite size. The most common stones are still about 1cm, and gallbladder stones are usually single or multiple, and there is no clear pattern. The treatment of gallbladder stones is mainly through surgical treatment, which is laparoscopic cholecystectomy and also includes some open cholecystectomy, mainly for patients who cannot undergo laparoscopic surgery; there is also a part of cholecystostomy for patients who cannot tolerate cholecystectomy. In conclusion, the treatment of gallbladder stones is mainly surgical, and general medication only controls the inflammation, however, it cannot achieve the effect of fundamental treatment of gallbladder stones.
