Gallbladder stones of 1.8 cm are close to the indication for surgery and need to be treated in conjunction with other manifestations as well as the patient’s wishes to decide whether or not to undergo surgical treatment. Gallbladder stones are a common digestive disease, mainly manifested as pain and discomfort in the right side of the upper abdomen, with episodes of epigastric colic. The current indications for surgery for gallbladder stones are: ① large number of stones and diameter ≥ 2~3 cm; ② calcified or porcelain gallbladder wall; ③ accompanied by gallbladder polyps; ④ thickening of the gallbladder wall, i.e., accompanied by chronic cholecystitis. Patients with gallbladder stones of 1.8 cm can choose to undergo surgical treatment to avoid subsequent attacks of biliary colic, in addition to other conditions of the patient’s gallbladder, such as whether it is a multiple stone, whether there is gallbladder fluid, whether the stone is in the gallbladder duct, etc., to comprehensively measure the need for surgical treatment. Patients with gallbladder stones should seek prompt medical attention and be treated aggressively.
