Gallbladder polyp lesions are clinically referred to as gallbladder polyp-like lesions, and gallbladder polyps refer to lesions that protrude or bulge into the lumen of the gallbladder, which are mostly benign and may be of little concern. Since it is difficult to diagnose the nature of gallbladder polyps before surgery, they are collectively referred to as gallbladder polypoid lesions. Pathologically, they can be divided into non-neoplastic polyps, such as cholesterol polyps, inflammatory polyps, hyperplastic polyps, lymphatic polyps, etc. Neoplastic polyps include adenomas, adenocarcinomas, etc. Polyps often increase gradually, and may be combined with gallbladder stones and gallbladder wall thickening, etc. Polyp-like lesions with a diameter of >1cm and a wide base have a certain possibility of malignant lesions and need active surgical treatment. Particular attention needs to be paid to middle-aged and elderly patients with lesions of 1-2 cm or more in diameter. Therefore, close follow-up should be performed when the presence of gallbladder polyp-like lesions is diagnosed, with a review in about six months to observe changes in polyp size and to avoid malignant development. Once the indication for surgery is reached, patients should be actively treated surgically by cholecystectomy and, if appropriate, radical gallbladder cancer surgery according to pathological findings.
