Gallbladder polyps are medically categorized as polypoid lesions of the gallbladder (PLG), which can be divided into pseudopolyps and true polyps. 1.Pseudopolyps: also known as non-neoplastic lesions, accounting for about 82% of patients with gallbladder polyps, mostly due to abnormal bile metabolism caused by cholesterol crystals precipitation, is a benign lesion, which is the most common gallbladder polyps, another kind of pseudopoly called inflammatory polyps, is due to repeated inflammation of the gallbladder, the inflammatory bulge in the wall of the gallbladder caused by local fibrous tissue hyperplasia. 2.True polyps: mainly including adenoma, adenomyoma adenoma and adenomatous hyperplasia, among which adenoma is a recognized precancerous lesion with a cancer rate of about 10%, and adenomatous hyperplasia also has potential cancer risk. Since the overall surgical efficacy of gallbladder cancer is very poor, it is not sensitive to radiotherapy and chemotherapy, and the surgical efficacy of gallbladder cancer is limited to early stage, the only way to improve the treatment effect is early detection and early removal of gallbladder. Therefore, although true polyps are benign tumors, they need to be paid great attention because they have the possibility of becoming cancerous under certain conditions. Ultrasound is the most commonly used method to check gallbladder polyps. Generally, multiple polyps are mostly pseudo polyps, while single polyps are more likely to be true, if ultrasound suggests that the polyps have blood supply, it indicates that they are true polyps, and if they are broad-based, more attention should be paid to them, if the polyps are larger, CT examination is also feasible, which is helpful to differentiate benign from malignant. In addition, if the diameter of a true polyp exceeds 1 cm, the possibility of malignant transformation is greatly increased and should be taken seriously. The choice of treatment: multiple polyps, if there is no discomfort and the polyp is less than 1cm, you can review the ultrasound every six months, and at the same time, you can take some oral anti-inflammatory and biliary drugs. If there is frequent right upper abdominal discomfort, dull pain, and no acid reflux and other gastric manifestations, it means that gallbladder polyps have caused symptoms, and surgery should be considered. Surgery should be considered in the following cases: 1. ultrasound describes polyps as solitary with wide base; 2. larger than 10mm; 3. lesions with significant short-term increase; 4. with gallbladder stones.
