About gallbladder polyps: 1. What is a polyp? A polyp is a tissue that protrudes from the surface. Such as nasal polyps, and gallbladder polyps are often found by ultrasound examination, is the surface of the gallbladder “elevated lesions”. Many people think of “cancer” when they see “lesions”, but there is no need to do so. Most of the bulging lesions seen under ultrasound are, by nature, cholesterol polyps and benign polyps, and only a few are adenomas and adenocarcinomas. For example, there are more than 500 cases of gallbladder removal in our department every year, among which there are no more than 10 cases of malignant tumors. 2.When should polyps be treated surgically? Many people ask for surgery because they are worried about the polyp becoming “malignant”. I have met a patient who found polyps for 3 years and was unwilling to accept surgery when the polyps grew to 2cm, and then the polyps reached 4cm in diameter half a year later, which was found to be malignant after immediate pathological examination and gallbladder cancer clearance. The currently accepted criteria for surgery are: diameter over 1 cm, age over 50 years, single lesion, polyps gradually increasing in size, and combined gallbladder stones. The example shown is a gallbladder stone combined with an adenomatous polyp: look again at the multiple cholesterol polyps.
