The term “gallbladder polyp” is a general concept, often referred to as gallbladder polyps, which are small lesions that protrude from the inner wall of the gallbladder into the lumen of the gallbladder, and are mostly found during ultrasound examinations. Most of the gallbladder polyps found by ultrasound are cholesterol crystals and cholesterol polyps are not cancerous. However, although true polyps and adenomas are benign lesions, they may become cancerous, and a very small number of gallbladder polyps are early manifestations of gallbladder cancer. As for the risk of cancer, the risk of cancer is greater for single polyps than for multiple polyps, and the risk of cancer is minimal for polyps with more than 3 polyps because most of them are cholesterol polyps; the risk of cancer is significantly greater for polyps with more than 1 cm than for polyps with less than 1 cm. And gallbladder cancer is a malignant tumor with poor prognosis. Most gallbladder polyps are asymptomatic, while those with gallbladder inflammation or gallbladder stones may have symptoms. For polyps less than 1cm in diameter, patients do not need any treatment as they have no symptoms, but they should be observed by ultrasound once every 3 months to 6 months, and if there is not much change, they can continue to be observed without surgery. The following cases should be operated: 1.Gallbladder polyps larger than 1cm; 2.Gallbladder polyps in a short period of time, such as the growth of 0.3cm or more within 3 months, even if its diameter does not reach 1cm, surgery, or close observation; 3.Gallbladder polyps combined with cholecystitis or gallbladder stones, there are obvious symptoms of cholecystitis; 4.B ultrasound found that the base of gallbladder polyps is wider, the polyps see blood flow, especially single polyp.
