Gallbladder polyp or gallbladder polyp-like lesion is a general term, generally speaking, the ultrasound report describes “gallbladder polyp-like lesion”, the so-called “polyp-like”, that is, like a polyp, but not necessarily a polyp. This is the name under the imaging examination, the specific gallbladder polyp is good or bad, pathological examination is the gold standard, but through the imaging characteristics can generally determine the benign and malignant. Gallbladder polyps generally have mild symptoms, or even asymptomatic; a few patients have epigastric discomfort, which can be accompanied by abdominal pain, discomfort or pain sites in the right upper abdomen or right quarter rib, a few can be accompanied by radiation to the right shoulder and back; polyps located in the neck of the gallbladder can appear biliary colic, in the combination of stones can be biliary colic attacks and acute and chronic inflammatory episodes of performance. The following types of gallbladder polyps are seen clinically: a. Cholesterol polyps: more than half of the gallbladder polyps found by ultrasound are of this type, which are not true polyps to be exact, but are believed to be cholesterol crystals formed on the mucosal surface of the gallbladder or cause mucosal elevation, and therefore are also called pseudopolyps. The current theory is that these polyps are not cancerous. Cholesterol polyps have the following characteristics: multiple, easily dislodged, mostly within 25px, mulberry-like in appearance, brittle and friable, with a thin tip like cotton thread, and mostly located in the body of the gallbladder. Cholesterol polyps are related to diet, and patients with high cholesterol diet or fatty liver are prone to get cholesterol polyps. No special treatment is needed for cholesterol polyps. It is recommended that: regular diet, breakfast, low cholesterol diet, and medications can be tried. For cholesterol polyps below 1 cm, regular ultrasound review can be done every 6 months to a year to observe the changes in size, shape and number. Second, non-cholesterol benign polyps: also known as true polyps, refers to a “meat” that really grows from the wall of the gallbladder, including adenoma, adenomyoma, inflammatory polyps, adenomatous hyperplasia, etc.. Inflammatory polyps are formed by long-term gallbladder stone irritation combined with chronic cholecystitis. Gallbladder adenoma is a benign tumor adenomyosis, adenomatous hyperplasia also has the risk of cancer. Early polyp-type gallbladder adenocarcinoma: Some patients with adenomatous gallbladder polyp diagnosed on ultrasound, but the postoperative pathology is adenocarcinoma, in fact, this type is not strictly speaking the category of gallbladder polyps. At present, it is sometimes difficult to identify polypoid early gallbladder cancer mixed with gallbladder polyps by ultrasound alone, and if necessary, thin enhancement CT or MRI enhancement scan should be done. The ultrasound characteristics of cancerous polyps are as follows: about 80% of them are larger than 25px and solitary; about 70% are located in the neck of gallbladder; about half are accompanied by gallbladder stones. Once such a lesion is suspected, it should be treated surgically as soon as possible. The gold standard for diagnosis is pathological diagnosis under the microscope. The nature of polyps cannot be determined directly under ultrasound, but can only be inferred empirically, so the term “gallbladder polyps” reported under ultrasound is usually a general term. However, ultrasound will generally describe the nature, whether it is multiple or single, size, etc. Treatment options: 1. If the polyp is less than 1 cm, the cholesterol polyp is mostly considered, the patient is advised to observe, but not to ignore it; about six months to do ultrasound, during the observation period to improve lifestyle habits and dietary structure (usually pay attention to eat more fresh fruits, vegetables and low-fat, low-cholesterol foods such as: mushrooms, fungus, celery, bean sprouts, kelp, lotus root, fish, chicken, fresh beans, etc.). Avoid eating some high cholesterol foods such as: eggs, fatty meat, seafood, animal offal, etc.; usually pay attention to drink more water) which is the most important. 2, a short period of rapid growth; greater than 1 cm; single; broad-based; gallbladder polyps; with local or whole gallbladder wall thickening; combined with gallbladder stones chronic cholecystitis; ultrasound, CT and nuclear magnetic does not exclude the possibility of cancer. From clinical experience, polyps with these characteristics have a high tendency to be “malignant”, and drug treatment is ineffective, so surgery is usually recommended before malignant transformation.
