“…Results from Western studies have shown a GBP prevalence of 1.4%-6.9% (10, 14, 15), whereas Asian studies have shown a GBP prevalence of 2.2%-9.5% (1, 16, 17). Such geographic differences may be associated with different genetic and environmental factors.…”

“…The prevalence of GBP peaked in men 30-39 yr of age in both of these periods. In most studies, the highest prevalence of GBP has been observed in the third to fifth decades of life (1, 16). The reasons for peak incidence of GBP in middle aged people are still unclear.…”

Shifting Prevalence of Gallbladder Polyps in Korea

Only a few studies have evaluated the population-adjusted prevalence of gallbladder polyps (GBP). This study aimed to evaluate the changes in GBP prevalence and risk factors at a single health screening center in Korea from 2002 to 2012. Of 48,591 adults who underwent health screening between 2002 and 2012, 14,250 age- and gender-matched subjects were randomly selected to evaluate prevalence. Risk factors were analyzed between the GBP-positive and GBP-negative groups during 2002-2004 (Period A) and 2010-2012 (Period B). The annual prevalence of GBP over the 11-yr period was 5.4%. Annual prevalence increased from 3.8% in Period A to 7.1% in Period B. Male gender and obesity were independent risk factors for GBP in both periods. Hepatitis B virus surface antigen (HBsAg) positivity was a risk factor for GBP in Period A but not in Period B. The risk factors for GBP changed from HBsAg positivity to lipid profile abnormalities. Other variables including age, hypertension, diabetes, impaired fasting glucose, chronic hepatitis C virus infection, and liver function tests did not correlate with GBP. In conclusion, GBP prevalence is increasing and risk factors for GBP have changed in Korea. More attention should be paid to this issue in the future.

“…Polyploid lesions of the gallbladder, which can be found in about 1-5% of adults on ultrasound in Western populations [152,153] and 9.6% in Asian populations [154], are defined as elevations of the gallbladder mucosa. Polyploid lesions of the gallbladder can be true polyps which demonstrate neoplastic changes and may be benign, dysplastic or malignant, or can be pseudopolyps such as cholesterol polyps, inflammatory polyps, or adenomyoma, which are all benign [152,155].…”

“…Seventyfour patients underwent sonography, including elastography of gallbladder polyps, in our institution. A polyp was defined on sonography as a lesion attached to the gallbladder wall that was non-shadowing, non-mobile and hyperechoic to bile [5,9]. Patients were included in the study if they had any of the following: sonographic follow-up for at least 2 years, pathology report, or who were diagnosed on the basis of characteristic clinical and radiologic findings.…”

Aims: Gallbladder polyps often have a benign nature. Current guidelines suggest surgical removal of polyps greater than 10 mm. However, the accuracy of the size criteria is limited because neoplasia can be found in gallbladder polyps less than 10 mm. The aim of this study was to evaluate the feasibility of real time elastography for gallbladder polyps and to demonstrate the elasticity properties of the polyps. Material and method: Fifty-three polypoid lesions of the gallbladder were prospectively examined with real-time elastography. Of these patients, 52 had a diagnosis of benign gallbladder polyps and one patient was accepted as a gallbladder carcinoma due to its clinical and radiological findings. B-mode and real-time elastographic images were simultaneously presented as a two-panel image, and the elastogram was displayed in a color scale that ranged from red (greatest strain, softest component), to green (average strain, intermediate component), to blue (no strain, hardest component). Results: The mean size for benign gallbladder polyps was 7.2 ± 3 mm (range, 5-21 mm). All benign gallbladder polyps on consecutive real-time elastographic images appeared as having a high-strain elastographic pattern. Only one patient who was accepted with gallbladder carcinoma had a gallbladder polyp with low elasticity properties. Conclusions: Our study showed that real time elastography of gallbladder polyps is feasible. This novel approach may be useful for the characterization of polypoid lesions of the gallbladder.

Prevalence of and risk factors for gallbladder polyps detected by ultrasonography among healthy Chinese: Analysis of 34 669 cases

Abstract: The prevalence of GB polyps among the Chinese in this study is higher than that reported for other populations. Chinese males and other patients with chronic hepatitis B viral infections have a high risk for developing GB polyps.
