Ultrasound examination of the gallbladder was performed in a prospective study (from 1985 to 1988) of 14,841 consecutive patients. Polypoid changes were found in 224 (129 men, 95 women; mean age 54 [18-88]years), sonographically classified as cholesterol polyps in 212, as polypoid lesions of uncertain benignity in 12. Mean observation time of 92 patients with cholesterol polyps was 9 (3-48) months. In six the polyp diameter increased by up to 5 mm: only two of them were operated upon and the diagnosis was confirmed in both. A total of 21 patients suspected of having cholesterol polyps were operated upon, the diagnosis confirmed in 17, chronic cholecystitis in two and, in one case each, thickened wall-adherent bile or wall-adherent concrements as cause of the ultrasound changes. Six of the 12 patients with polypoid lesions of uncertain benignity were operated upon: two had an adenoma, one each had tissue heterotopy, malignant melanoma metastasis, gall-bladder carcinoma and adenomyomatosis.

The prevalence of gallbladder polyps as assessed by ultrasonography in a random population was 4.6% among men and 4.3% among women. The size of most polyps was 3 mm or more but never exceeded 10 mm. The prevalence of polyps was not significantly associated with age, sex, social factors, weight factors, physical activity, diabetes mellitus, pregnancies, use of exogenous female hormones, intake of alcohol, or plasma lipids. Polyps among men were significantly associated with a history of no smoking. This lack of risk factor profile resembled that of cholesterolosis, as seen in the literature, whereas it was quite different from that of gallstones. It is concluded that polyps in the gallbladder are common in a random population, and, although it is known from the literature that some cases may represent gallstones, the vast majority most probably represent the polypoid variation of cholesterolosis.
