Gallbladder polyps are broadly divided into three types. Cholesterol polyps are multiple and generally do not exceed 3MM in diameter, which are not cancerous, so they do not need to be treated; inflammatory polyps are multifocal mucosal hyperplasia on the background of gallbladder inflammation, which are rarely cancerous, but if the gallbladder inflammation is long and affects the quality of life, it is better to remove them; the third type is true polyps, which are generally solitary, varying in size, and more than 10MM are prone to cancer and should be especially alert. The following conditions should be operated in time: 1. older patients; 2. single polyps or polyps with less occurrence, diameter greater than 8MM; 3. recent ultrasound examination found that the polyps have grown significantly; 4. recent occult pain or pain in the gallbladder area. In fact, it is incomplete and even wrong to decide whether to operate by the size of polyps. Polyps do not tell you when they will change, and once clinical symptoms or ultrasound suggests cancer, it is often too late. Happily, with the improvement of people’s economic and cultural level and the enhancement of disease prevention awareness, especially the emergence of laparoscopic cholecystectomy, the occurrence of gallbladder polyp carcinoma has been significantly reduced.
