The majority of gallbladder polyps do not cause any symptoms and are only detected incidentally during an ultrasound physical examination. A small percentage of people will experience varying degrees of right upper abdominal tightness or biliary colic, which may be due to a polyp growing near the gallbladder duct. Polyps obstruct the flow of bile from the cystic duct, which is a very thin duct that drains bile outward, causing discomfort and pain due to increased pressure in the cavity of the gallbladder, which can lead to chronic cholecystitis over time. The above-mentioned manifestations in people with polyps combined with stones may still be mainly related to stones. There are three different types of gallbladder polyps (cholesterol polyps, inflammatory polyps, and adenomatous polyps), and cholesterol polyps and inflammatory polyps are not harmful to health and life if they do not cause clinical symptoms. Adenomatous polyps are tumors that have a tendency to become malignant, and it should be said that this is the greatest potential threat. According to the current level of imaging technology, we can only generally distinguish the nature of polyps, and it is even more difficult to determine whether the polyps are cancerous in the early stage. However, adenomatous polyps are rare, less than 1% in total, and whether malignant changes occur or not is closely related to the size of the polyps. By summarizing and analyzing a large number of cases, we found that there are almost no malignant polyps below 1 cm, and once the polyps grow more than 1 cm, the chance of cancer increases steeply to 2%-13%, and some medical literature reports even more than 20%.
