With the widespread use of ultrasound instruments, gallbladder polyps are increasingly being detected. What is meant by gallbladder polyps? The gallbladder polyp suggested by ultrasound report is actually a generic term for the raised lesions on the mucosa of the gallbladder lining, which includes common cholesterol polyps, small gallbladder adenomas; also includes uncommon small smooth muscle tumors, lipomas, fibroids, granulocytomas, gallbladder cancer, etc. All of these are difficult to distinguish by ultrasound when they are relatively small, so not all gallbladder polyps are reassuring and not all of them are Therefore, not all gallbladder polyps are reassuring or worry-free. The following is a description of the different ultrasound features and commonalities of these “polyps”. Cholesterol-like polyps: These are formed when cholesterol is deposited on the wall of the gallbladder due to a local disorder of cholesterol metabolism and an increase in the cholesterol content in the bile. Its ultrasound characteristics are multiple, small, within 1 cm, tipped and small, hyperechoic, no acoustic shadow, nodules are not round, no blood flow signal in the nodules, attached to the wall of the cyst, and some polyps are dislodged and discharged from the gallbladder. Most of the gallbladder polyps reported by ultrasound are cholesterol polyps, which will not grow up after years of ultrasound observation and are not harmful to people, so there is no need to worry too much. Gallbladder adenoma: It is divided into simple gallbladder adenoma and papillary gallbladder adenoma, the former is benign and the latter is malignant, or precancerous lesion. This disease is difficult to distinguish from cholesterol polyps when smaller (less than 1 cm), but its ultrasound features are more solitary, small in size (average 5.5 cm), round nodules, occasional tissues, non-dislodging, attached to the cyst wall, low echogenicity, no acoustic shadow, and smaller ones with no blood flow signal. This type of adenoma has the possibility of malignancy as soon as it grows, and those with a tip are not prone to malignancy, while those without a tip are prone to malignancy. Those smaller than 1 cm are not prone to malignancy, while those larger than 1 cm are prone to malignancy. According to these characteristics, polyps that are single, round and low in echogenicity should be of special concern and should be examined by ultrasound once in six months for early treatment. In addition to the above adenoma characteristics, papillary gallbladder adenoma is often accompanied by chronic cholecystitis, gallstones and corresponding uncomfortable symptoms, and it is best not to delay and operate early if you find such gallbladder polyps, regardless of size. Gallbladder cancer: It has a distribution characteristic, mostly at the bottom of gallbladder, followed by the body and neck, without a tip, not round, mostly block-shaped, papillary-shaped, with low internal echogenicity, internal blood flow signal, etc. These phenomena are usually indicated in the report by ultrasonographers. These phenomena are usually indicated by the ultrasonographer on the report. Early diagnosis and surgery can be made when such reports are found. Other types of gallbladder augmentation-like lesions such as smooth muscle tumors, lipomas, fibromas, and granulosa cell tumors are rare and characterized by roundness and large size. Nodules larger than 1 cm should be operated. The above suggests that gallbladder polyps less than 1cm that are solitary, non-tipped, round, hypoechoic, and located at the base of the gallbladder should be checked regularly to observe changes, with ultrasound once every six months; multiple, tipped, hyperechoic polyps once a year; block-shaped, papillary-shaped, hypoechoic, hemorrhagic, symptomatic gallbladder augmentation-like lesions should be operated early. Polyps of any form larger than 1 cm should be taken seriously and preferably surgically removed except for those clearly identified as cholesterol polyps.
