The vast majority of gallbladder polyps are not clinically harmful, and in rare cases gallbladder polyps may cause serious consequences. The majority of lesions belong to pseudopolyps, which are cholesterol monohydrate crystals formed by the imbalance of bile acid and cholesterol dissolution. Most of them have no obvious clinical symptoms and are found unintentionally during physical examination. A small number of true gallbladder polyps, that is, mucosal hyperplasia of the gallbladder, may cause malignant transformation if they are of broad basal type and have a diameter of more than 1 cm. Currently in clinical practice for gallbladder cancer, if the lesion is stage III or above, the overall cure rate is usually low and the prognosis is relatively poor. In addition, relatively small gallbladder polyps may develop biliary pancreatitis when the polyps are expelled.
