Gallbladder benign tumor

Benign tumor of the gallbladder is a rare disease. In recent years, due to the development and application of imaging diagnostic technology, especially the widespread application of B-ultrasound technology in biliary surgery, the detection of benign gallbladder tumors has increased significantly. According to incomplete statistics in China, benign gallbladder tumors account for 4.5% to 8.6% of cases of cholecystectomy in the same period. The nomenclature of benign tumors of the gallbladder wall is confusing. In the previous literature, benign tumors of the gallbladder are collectively referred to as papilloma or polyp. Japanese scholars call it gallbladder-like lesions. In recent years, it is often used in China as a polypoid lesion of gallbladder (PLG). None of the above names are perfect. In fact, gallbladder-like lesions in Japan also include gallbladder cancer. Benign tumors of the gallbladder are not entirely polypoid lesions. The above nomenclature is therefore merely a diagnostic term for morphology and imaging.
