Fast Morphological Gallbladder Changes Triggered by a Hypercholesterolemic Diet.
Annals of Hepatology 2018 August 25
INTRODUCTION AND AIM: Obesity is a worldwide epidemic problem, described as a risk factor for hepatic diseases, such as non-alcoholic fatty liver disease and other pathologies related to development of cholesterol crystals and cholesterol gallbladder stones. It has been reported that cholesterol overload may cause hepatic damage; however, little is known about the effects of an acute hypercholesterolemic diet on the gallbladder. The aim of this manuscript was to evaluate the impact of a cholesterol-rich diet on the gallbladder.
MATERIAL AND METHODS: The study included ten eight-week-old C57BL6 male mice, which were divided into two study groups and fed different diets for 48 h: a hypercholesterolemic diet and a balanced Chow diet. After 48 h, the mice were analyzed by US with a Siemens Acuson Antares equipment. Mice were subsequently sacrificed to carry out a cholesterol analysis with a Refloton System (Roche), a crystal analysis with a Carl Zeiss microscope with polarized light, and a histological analysis with Hematoxylin-eosin staining.
RESULTS: The hypercholesterolemic diet induced an increase in gallbladder size and total cholesterol content in the bile, along with important histological changes.
CONCLUSION: Cholesterol overloads not only trigger hepatic damage, but also affect the gallbladder significantly.
