I. What is a gallbladder polyp? Clinically, gallbladder polyp or polypoid lesion of the gallbladder is a general term used by medical imaging for a protruding lesion on the inner wall of the gallbladder. There are several clinical conditions: 1. Cholesterol polyps: also known as pseudopolyps, which account for about 65% of all gallbladder polyps. It has a mulberry-like appearance, brittle and fragile, with a thin tip, extremely easy to fall off, mostly within 10mm, thought to be multiple. Most patients with cholesterol polyps are asymptomatic or have mild symptoms and good gallbladder function. Cholesterol polyps are related to diet. Patients with high cholesterol Калогание diet or fatty liver are prone to cholesterol polyps. Patients with cholesterol polyps are advised to have a regular diet, low cholesterol diet and avoid alcohol. Excessive cholesterol intake (egg yolk, fatty meat, fish without scales, animal offal, etc.) can exceed the metabolism of liver and gallbladder, causing excess cholesterol to crystallize and precipitate in the gallbladder wall, thus forming cholesterol polyps. 2, non-cholesterol benign polyps: also known as true polyps, accounting for about 30% of the total. They mainly include: adenoma of gallbladder, adenomyoma of gallbladder, inflammatory polyp, adenomatous hyperplasia and so on. Among them, inflammatory polyps are formed by long-term gallbladder stone stimulation combined with chronic cholecystitis. Gallbladder adenoma is a benign tumor, which is a precancerous lesion of gallbladder, with a cancer rate of about 30%. Adenomatous hyperplasia and adenomatous hyperplasia of the gallbladder also have the risk of cancer. This type of patient is ineffective in drug treatment, so bile preservation and drug treatment are not recommended, and cholecystectomy is recommended. 3. Polypoid early gallbladder adenocarcinoma: It accounts for about 5% of the total number of patients, and is not strictly speaking the category of gallbladder polyps anymore. At present, it is often difficult to identify polypoid early gallbladder cancer mixed with gallbladder polyps by ultrasound alone. Ultrasound features of cancerous polyps are: about 80% or more are larger than 10mm, solitary, combined with gallbladder stones, and mostly located in the neck of gallbladder. Once such a lesion is suspected, it should be treated by surgery as soon as possible. Second, how to treat gallbladder polyps? The surgical treatment of gallbladder polyps has two aspects, on the one hand, it is to prevent cancer or leakage of cancer, which mainly refers to the latter two types of polyps mentioned earlier. On the other hand, if the symptoms are not relieved by medication, and if the chronic cholecystitis affects normal work and life, laparoscopic minimally invasive cholecystectomy should be considered. Surgery is usually recommended for gallbladder polyps that grow rapidly within a short period of time, are greater than 10 mm in length, are solitary, and have a wide base; or are associated with local or whole thickening of the gallbladder wall; or are combined with gallbladder stones; and are not excluded from the possibility of cancer.
