Gallbladder polyps of 2 millimeters are usually observed and followed up, and surgical resection should be considered if the polyp grows larger than 1 cm, has a tendency to malignancy, or causes clinical symptoms. Gallbladder polyp is a limited elevated lesion that occurs in the gallbladder wall towards the gallbladder cavity, including cholesterol polyp, inflammatory polyp and other types. Generally speaking, if the diameter of gallbladder polyps is less than 2mm, and there is no malignant tendency and no clinical symptoms, it is usually enough to observe and follow up. If the diameter of the polyp is more than 1cm, it means that the tendency of the polyp to become cancerous will increase; meanwhile, the polyp may also be accompanied by symptoms such as distension and pain in the right upper abdomen. For these cases, it is necessary to take timely surgical treatment to remove the gallbladder in order to reduce the risk of malignant changes. It is recommended to consult a doctor for standardized diagnosis and treatment when necessary.
