Cholesterolosis. Incidence, correlation with serum cholesterol level and the role of laparoscopic cholecystectomy.
ABSTRACT To report the incidence of cholesterolosis in the surgically removed gallbladders, its association with serum cholesterol level and to review the role of laparoscopic cholecystectomy in the treatment.
This retrospective study included all patients who had consecutive cholecystectomies for various gallbladder disorders, performed by 2 consultants during a 5-year period from January 1997 through to December 2002, in the College of Medicine and King Khalid University Hospital, King Saud University, Riyadh, Kingdom of Saudi Arabia. The clinical records of those found to have cholesterolosis on histopathological examination were reviewed, and the data were analyzed for their age, sex, fasting serum cholesterol level and the final outcome of cholecystectomy.
The study group was comprised of 549 patients and out of which, 74 (13.4%) had cholesterolosis of the gallbladder. There were 59 (79.9%) female and 15 (20.1%) male patients. Age ranged from 18-64-years with a mean of 35.7-years. Sixty-three (85.1%) cases were reported to have abnormally high fasting serum cholesterol levels (>=5.5 mmol/L), whereas 11 (14.9%) had normal serum cholesterol level. Cholesterolosis with coexistent gallstones was documented in 47 (63.3%) patients while 27 (36.5%) subjects showed acalculous cholesterolosis. Laparoscopic cholecystectomy was performed in 71 (95.9%) individuals, whereas 3 patients ended up with open cholecystectomy (conversion rate of 4.2%). There were no postoperative complications.
Cholesterolosis of the gallbladder is a distinct pathologic entity and carries a positive correlation with high serum cholesterol level. Laparoscopic cholecystectomy is effective, safe and a feasible treatment modality for cholesterolosis.

ABSTRACT: 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.Journal of Korean Medical Science 09/2014; 29(9):1247-52. DOI:10.3346/jkms.2014.29.9.1247 · 1.25 Impact Factor

ABSTRACT: Objective: Gallbladder stones are common in the Western world, and 70% to 80% of gallstones are cholesterol stones. This study investigates the effects of serum cholesterol, LDL, and HDL levels on gallstone cholesterol concentration. Methodology: The gallstones of 75 patients with cholelithiasis were examined using spectrophotometry. Results: High serum cholesterol and LDL levels were associated with high cholesterol stone rates (86.7% vs. 40.0%, P < 0.001; 75.0% vs. 48.9%, P < 0.05, respectively). Similarly, high serum cholesterol and LDL levels were correlated with high gallbladder stone cholesterol concentrations (63.6% vs. 44.4%, P < 0.001; 62.3% vs. 46.0%, P < 0.001, respectively). In contrast, low serum HDL levels do not seem to affect the occurrence of gallbladder cholesterol stones (60.0% vs. 58.3%, respectively, P > 0.05) or gallbladder stone cholesterol concentrations (50.8% vs. 52.4%, respectively, P > 0.05). Conclusion: The relationship between cholesterol, LDL, and HDL levels and cholesterol gallstone formation is multifactorial and complex and is also dependent on other individual properties.Pakistan Journal of Medical Sciences Online 09/2013; 29(1):187-90.

ABSTRACT: To investigate the prevalence and risk factors of polypoid lesions of gallbladder (PLG) among the health examinees in the Shanghai region, China. A total of 11,816 subjects who underwent health examinations in our hospital between August 2010 and February 2011 were analyzed retrospectively. Among them, there were 7174 men and 4642 women. PLG was diagnosed by the real-time ultrasonography. Those with the body mass index (BMI) ≥ 28 were considered to be obese. Blood biochemical indices were detected with the fully automatic biochemical analyzer and hepatitis B surface antigen (HBsAg) was tested by the automated enzyme immunoassay. The correlations between the prevalence of PLG and age, sex, BMI, serum cholesterol (T-Cho), triglycerides (TG), blood sugar, HBsAg, high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C), gallstone and fatty liver were investigated. After univariate analysis of 11 variables, stepwise logistic regression analysis was performed to explore the risk factors of PLG. There was a significant difference in sex, T-Cho, HBsAg, HDL-C, LDL-C and fatty liver between the PLG-positive group and the PLG-negative group (332/163 vs 6842/4479, P = 0.003; 22/473 vs 295/11,026, P =0.013; 92/403 vs 993/10,328, P = 0.001; 47/448 vs 332/10,989, P = 0.001; 32/463 vs 381/10,940, P = 0.001; 83/412 vs 3260/8061, P = 0.001). No significant difference was found in the age, BMI, TG, blood sugar and gallstone between the two groups (47.3 ± 26 vs 45.1 ± 33, P = 0.173; 59/436 vs 1097/10,224, P = 0.102; 52/443 vs 982/10,339, P = 0.158; 17/478 vs 295/11,026, P = 0.26; 24/471 vs 395/10,926, P = 0.109). Logistic regression analysis showed that the sex, HBsAg and HDL-C were independent risk factors for the development of PLG in a descending order of HDL-C > HBsAg > sex. In healthy people, the male gender, positive HBsAg, and low HDL-C confer higher risks of PLG development.World Journal of Gastroenterology 06/2012; 18(23):3015-9.
