Benign lesions on the gallbladder, usually called polyps until a definitive pathology is obtained, include: cholesterol crystals, adenomyosis of the gallbladder and adenoma of the gallbladder. Such lesions account for 3% to 7% of routine abdominal ultrasound examinations and are found in 2% to 12% of post-surgical gallbladder specimens . 1. Cholesterol polyps are common benign lesions in the gallbladder, usually less than 10 mm in size, appearing as a bulge on ultrasound and taking the shape of a mushroom, and 30% of cholesterol polyps are multiple. 2. In contrast, adenomyosis of the gallbladder appears sessile on ultrasound and has many small cysts, mostly larger than 10 mm in size. 3, Gallbladder adenoma is usually difficult to distinguish from gallbladder cancer, and the main difference is the presence or absence of crossing the muscle layer in ultrasound examination. Gallbladder polyps have the possibility of malignant transformation when they are older than 60 years old, combined with gallbladder stones, larger than 10 mm in diameter and rapidly increasing in size. Therefore, patients with gallbladder polyps should follow the following treatment strategies: 1, clinically there are already symptoms, such as distension and pain in the right upper abdomen or under the quarter ribs, swelling and pain in the back, etc. At this time, patients with gallbladder polyps should choose surgery to remove the gallbladder regardless of the size of the polyps. 2.Gallbladder polyps >10 mm should be selected for surgical treatment. 3.Gallbladder polyps <10 mm, but age >60 years, combined with gallbladder stones, porcelain gallbladder, should be surgically removed from the gallbladder. 4.Gallbladder polyps <10mm, no clinical symptoms, less than 60 years old, no gallbladder stones and porcelain gallbladder comorbidities, should be followed up clinically, at least once every six months by ultrasound, the follow-up time is not shorter than 2 years, during the follow-up polyps grow rapidly then surgery, no change then clinical observation, no need to deal with.
