If the gallbladder is found to be occupied during the examination, the following diseases may be considered: first, gallbladder stones, some patients with gallbladder stones may present an occupied lesion due to their large gallbladder stones, which have existed for a long time and have become adherent to the surrounding gallbladder tissue. Second, cholangiocarcinoma, another disease that causes the gallbladder to become occupied is cholangiocarcinoma, which is a malignant disease and may be related to genetic factors. Thirdly, liver cancer, some patients with liver cancer will also have gallbladder metastasis, but in addition to gallbladder occupancy, the liver will also show obvious lesions. After the above cases are found, they must be treated by surgical resection in time to have a good healing.
