Polyps of the gallbladder are incidental findings during radiological imaging of the abdomen. The polyps are more often benign (cholesterol polyps, adenomyomas, inflammatory , adenomas or miscellaneous) but may be malignant (adenocar cinoma [80%] or squamous cell carcinoma, or cystadenomas). A majority of polyps remain stable. Cholecystectomy should be considered in symptomatic patients or as prophy laxis to prevent malignant transformation in those who also gallstones, primary sclerosing cholangitis (PSC), biliary have Carl Freiherr von Rokitansky , 1804–1878, pathologist, Vienna, Austria.

Polyps in patients older than 50 years, sessile polyps with wall thickening greater than 4 /uni00A0 mm and pol - yps larger than 10 /uni00A0 mm merit cholecystectomy . Smaller polyps should be kept under observation and need surgery if the size is increasing.
