RESUMEN
Gallstone disease represents one of the most common gastroenterological disorders. Several risk factors for cholesterol gallstone formation in the general population have been identified. There is a strongly increased risk of gallstone disease during prolonged fasting, rapid weight loss, total parenteral nutrition, and somatostatin analogue treatment. Cholecystectomy is the most frequently recommended conventional treatment for symptomatic gallstones. In asymptomatic and symptomatic gallstone carriers, treatment with the hydrophilic bile salt ursodeoxycholic acid (UDCA) has been claimed to reduce the risk of biliary colic and gallstone complications such as acute cholecystitis and acute pancreatitis. However, randomized, double-blind, placebo-controlled trials are lacking. There is evidence that dietary factors influence the risk of developing cholesterol gallstones. Dietary factors that may increase risk include cholesterol, saturated fat, trans-fatty acids, refined sugar, and possibly legumes. Obesity is also a risk factor for gallstones. Dietary factors that may prevent the development of gallstones include polyunsaturated fat, monounsaturated fat, fiber, and caffeine. Consuming a vegetarian diet is also associated with decreased risk. In addition, identification and avoidance of allergenic foods frequently relieves symptoms of gallbladder disease, although it does not dissolve gallstones. Nutritional supplements that might help prevent gallstones include vitamin C, soy lecithin, and iron. In addition, a mixture of plant terpenes (Rowachol(R)) has been used with some success to dissolve radiolucent gallstones.

BACKGROUND/AIMS: Diabetes is one of the risk factors of gallstone diseases. Many studies found a positive association between insulin and gallstones in individuals with diabetes. However, this association is unclear in non-diabetes. So we conducted a case-control study for the evaluation of the association between gallstone diseases and fasting serum insulin level, insulin resistance in non-diabetic Korean general population. METHODS: This study was a prospective case-control study on 118 Korean subjects which included clinical examination, abdominal ultrasound, and blood chemistries. Serum fasting insulin level were determined by radioimmunoassay and concentrations of cholesterol, glucose, and triglycerides by standard enzymatic colorimetric methods. Insulin resistance was determined by the homeostasis model assessment (HOMA-IR). Body mass index (BMI), percentage of body fat, and waist hip ratio were also measured. RESULTS: We studied 118 subjects with no clinical evidence of diabetes mellitus and serum glucose<126 mg/dL. Compared with controls (n=89), cases (n=29) had higher levels of serum insulin, glucose, triglyceride levels, and BMI. In t-test and chi-square test for variables, the association between gallstone disease and serum insulin, HOMA-IR index, and BMI were statistically significant (p<0.05). In multiple logistic regression analysis, gallstone disease risk increased with the level of serum insulin (p=0.024, odds ratio=1.376) and HOMA-IR index (p=0.013, odds ratio=2.006). CONCLUSIONS: We suggest that hyperinsulinemia and insulin resistance could be associated with gallstone formation in individuals without clinical diagnosis of diabetes mellitus and with normal serum glucose level.
