Gallbladder polyps vary in size each time and may be associated with multiple gallbladder polyps or enlarged or cancerous gallbladder polyps, etc. They can be treated according to the size and associated risk factors, etc. Gallbladder polyps are generally defined as elevated or protruding lesions in the gallbladder lumen that are papillary, spherical, hemispherical, and may be tipped, and are most often detected by ultrasound during physical examination. Inflammatory gallbladder polyps can be multiple, often combined with cholecystitis and gallbladder stones, and the diameter is often less than 1 cm. Polyps can increase in size due to irritation, so the size varies from one examination to the next. A small number of gallbladder polyps can become cancerous, and some risk factors such as enlargement of gallbladder polyps, diameter more than 1cm, combined with gallbladder polyps and thickening of the gallbladder wall, single lesion with a wide base, etc., can cause malignant transformation of polyps, especially if the diameter of the polyp is more than 2cm, which is more important to pay attention to. If the diagnosis of gallbladder polyps is confirmed, without clinical symptoms and the above risk factors for malignant transformation, there is no need for surgical treatment, and regular review is needed; if obvious symptoms and malignant factors occur, surgical treatment is needed and further diagnosis is needed.
