OBJECTIVE: To investigate whether total body fat mass or fat distribution and associated metabolic disturbances in glucose and lipid metabolism influence the well known gallstone pathogenetic factors in obese subjects in order to explain why some obese subjects develop gallstones and some do not.

DESIGN: Cross sectional study of gallstone pathogenetic factors, body composition, fat distribution, glucose and lipid metabolism.

SUBJECTS: 57 healthy overweight subjects (aged 26-64y, body mass index (BMI) 30-45 kg/m2).

MEASUREMENTS: Total and intra-abdominal fat masses were measured by dual X-ray absorptiometry and abdominal CT scanning, respectively. The lithogenic index was measured in aspirated bile. The gallbladder volume was determined by ultrasound and the gallbladder ejection fraction% by dynamic cholescintigraphy. Plasma cholecystokinin (CCK) concentrations during a meal were measured with a specific radioimmunoassay. Insulin sensitivity was measured by the Minimal Model and glucose tolerance by an oral glucose tolerance test (OGTT). Serum lipid concentrations were measured by standard methods.

RESULTS: The gallbladder volume in the fasting state increased with increasing intra-abdominal fat mass (P=0.006) and was increased in subjects with impaired glucose tolerance (41 vs 27 ml, P=0.001). The lithogenic index was > 1 in all subjects and correlated with total fat mass (P=0.04).

CONCLUSION: Gallstone pathogenesis in obesity seems to be influenced by the total body fat mass and its regional distribution possibly via mutual association with the glucose tolerance.
