We aimed to evaluate the prevalence of non-alcoholic steatohepatitis and metabolic syndrome in patients with symptomatic gallstones undergoing laparoscopic or open cholecystectomy.
A study of 95 patients was performed. Simultaneous liver biopsies were taken during cholecystectomy between 2006 and 2007. There were no postoperative complications. Patients with significant alcohol intake, hepatitis B or C (virus-positive), autoimmune diseases, and Wilson's disease were excluded. Demographics, liver function tests, lipid profile, and ultrasound findings of patients with and without non-alcoholic steatohepatitis were compared.
A total of 95 patients completed the study. The mean age was 52.15 years, and 29 patients were male and 66 female. Fifty-two patients (55%) had biopsies compatible with non-alcoholic steatohepatitis.
Fifty-five percent of patients with gallbladder stones had associated non-alcoholic steatohepatitis. Awareness of this association may result in an earlier diagnosis. The high prevalence of non-alcoholic steatohepatitis in patients with gallbladder stone may justify routine liver biopsy during cholecystectomy to establish the diagnosis and stage and possibly direct therapy.
"GD is the most common disorder of the gastrointestinal tract and it is strongly associated with metabolic risk factors.9,10 Because hepatic steatosis is currently considered as the hepatic manifestation of the MS,7,8 interest is mounting on the potential relationships between NAFLD and GD.12,13,14,15,16,17,18,19,20 To our knowledge, this is one of the largest report to date focusing on the association between biopsy-proven NAFLD and GD. "
[Show abstract][Hide abstract] ABSTRACT: We sought to examine whether the presence of gallstone disease (GD) in patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD) is associated with liver fibrosis and histological nonalcoholic steatohepatitis (NASH) score.
We included 441 Turkish patients with biopsy-proven NAFLD. GD was diagnosed in the presence of sonographic evidence of gallstones, echogenic material within the gallbladder with constant shadowing and little or no visualization of the gallbladder or absence of gallbladder at ultrasonography, coupled with a history of cholecystectomy.
Fifty-four patients (12.2%) had GD (GD+ subjects). Compared with the GD- subjects, GD+ patients were older, had a higher body mass index and were more likely to be female and have metabolic syndrome. However, GD+ patients did not have a higher risk of advanced fibrosis or definite NASH on histology. After adjustment for potential confounding variables, the prevalence of GD in NAFLD patients was not associated with significant fibrosis (≥2) (odds ratio [OR], 1.06; 95% confidence interval [CI], 0.53 to 2.21; p=0.68) or definite NASH (OR, 1.03; 95% CI, 0.495 to 2.12; p=0.84).
The presence of GD is not independently associated with advanced fibrosis and definite NASH in adult Turkish patients with biopsy-proven NAFLD.

"Our results indicated that NAFLD was associated with incident GSD after adjustment for confounding factors.The association between NAFLD and GSD is based upon associated risk factors and metabolic derangements that are common to both conditions. From the preventive medicine viewpoint, modifiable risk factors for GSD and NAFLD include obesity and metabolic syndrome, both of which can be addressed with weight loss, exercise and dietary modifications such as a low-fat, low-sugar diet .

[Show abstract][Hide abstract] ABSTRACT: Gallstone disease (GSD) is a common gastrointestinal disorder throughout the world. The authors explored the incidence of GSD in Taiwan and its condition-associated predictive factors.
The initial study cohort comprised 2386 healthy adult participants, who were voluntarily admitted to a teaching hospital for a physical check-up in 2002 in Taipei, Taiwan. After excluding 126 patients who exhibited prevalent GSD, 2260 non-GSD participants received annual follow-up screenings for GSD until 31 December, 2007. Of those, 1296 (57.3%) patients were re-examined to collect blood samples and conduct ultrasound sonography.
Among the 1296 participants who exhibited no GSD at the first screening, 23 patients developed GSD during 3640 person-years of follow-up. The incidence was 0.632% per year (95% CI: 0.292%-2.009%). After conducting a Cox regression, increased age (50-59 years versus < 40 years, RR = 2.16 [95% CI: 1.09-5.97], 60+ years versus < 40 years, RR = 3.81 [95% CI: 2.77-8.63]), high body mass index (>=27 kg/m2 versus < 24 kg/m2, RR = 1.64 [95% CI: 1.07-2.98]), high fasting plasma glucose levels (>=126 mg/dL versus < 110 mg/dL, RR = 1.68, 95% CI: 1.10-3.87), and nonalcoholic fatty liver disease (yes versus no, RR = 1.44, 95% CI: 1.21-1.90) appeared to be significantly related to developing GSD.
Increased age is a well-established risk factor for developing GSD. The current findings indicated that high body mass index, elevated fasting plasma glucose levels, and nonalcoholic fatty liver disease were also associated with GSD.
[Show abstract][Hide abstract] ABSTRACT: Little is known about risk factors for biliary pancreatitis in children. We characterized cases of pediatric biliary pancreatitis, compared biliary with nonbiliary cases, examined differences in presentation between younger and older children, and studied features distinguishing gallstone- from sludge-induced pancreatitis.
We evaluated 76 episodes of biliary pancreatitis from 271 cases of acute pancreatitis in children admitted to a tertiary care hospital from 1994 to 2007.
Of the 76 cases, 55% had gallstones, 21% had sludge, and 24% had structural defects. Hispanic children had 2.85 (P = 0.01) and 5.59 (P = 0.003) times higher probability for biliary pancreatitis than white and black children, respectively. Median serum amylase and lipase in children with biliary pancreatitis were 64% and 49% higher, respectively, compared with other causes (P < 0.05). In multiple logistic regression, aspartate aminotransferase was an independent predictor of biliary pancreatitis (odds ratio 6.69, P = 0.001). When comparing gallstone- with sludge-induced causes, obesity was an independent predictor (38% more prevalent, P < 0.01) of gallstone cases.
Hispanic ethnicity is a risk factor and aspartate aminotransferase is a biomarker for biliary pancreatitis over other causes. Furthermore, obesity can distinguish gallstone- from sludge-induced pancreatitis. These findings may spur prospective studies to determine the optimal evaluation and management of children with biliary pancreatitis.
