Gallbladder polyps refer to a group of lesions that protrude or bulge into the lumen of the gallbladder and are mostly benign. They can be divided into neoplastic polyps, such as adenomas and adenocarcinomas, and non-neoplastic polyps, such as cholesterol polyps and inflammatory polyps with adenomyosis. It is difficult to determine the nature before surgery, so collectively they are called gallbladder polypoid lesions. Most of them are asymptomatic. However, the following conditions are considered as risk factors for malignant lesions: diameter over 1 cm, age over 50 years, solitary lesion, progressive increase in polyp size, limited thickening of the gallbladder wall or wide basal polyps, combined gallbladder stones, etc. Surgery should be considered for those with significant symptoms and those with the above risk factors for malignancy. Except for some cholesterol polyps that can be treated with medication, other types of polyps are not very effective. Drug therapy combined with dietary modification is more effective for cholesterol polyps.
