Serum lipids and lipoproteins in patients with gallstone (relationship between serum lipids and types of stones in roentgenograms and sectional views)

Serum lipids and lipoproteins of gallstone patients were analyzed and compared with lithogenesity of bile and type of stones by roentgenographic and cross-sectional views.
Incidences of hypercholesterolemia and triglyceridemia were higher in patients with radiolucent gallstones than with radiopaque stones. Furthermore, an incidence of hypertriglyceridemia was higher in patients with radiolucent solitary stones than with radiolucent multiple stones. The degrees of hyperlipidemia were moderate.
Lipoprotein disc electrophoresis of sera of hyperlipidemic patients revealed type IIa, IIb or IV. More solitary and less multiple stones were seen in the hyperlipoproteinemic patients than normolipoproteinemic. Multiple stones with normolipoproteinemia were more accompanied by unsaturated bile (lithogenic index <1.0) than those with hyperlipoproteinemia and solitary stones with hyperlipoproteinemia or without.
Solitary stones obtained surgically from normolipoproteinemic patients were pure cholesterol, combination or mixed stones, while multiple stones not including pure cholesterol and combination stones with pure cholesterol in the center. Solitary stones in hyperlipoproteinemic patients proved mostly either pure cholesterol or combination stones with pure cholesterol in the center, while multiple stones containing all types of stones inclusive of a small number of other miscellaneous stones except cholesterol stones. Collectively more mixed and other miscellaneous stones except cholesterol stones, and less pure cholesterol and combination stones with pure cholesterol in the center were shown in normolipidemic patients, and vice versa in hyperlipoproteinemic patients.
These results suggested serum lipids and lipoproteins being closely related to the initial precipitation, aggregation of cholesterol crystals and development of cholesterol gallstones through lipid metabolism of the whole body.
