Overview
It has long been noted that gallbladder stone formation is associated with bile supersaturation, and this still remains the most common cause for gallstone formation.[1]
Pathophysiology
Researchers believe that gallstones may be caused by a combination of factors, including:
- Inherited body chemistry
- Body weight
- Gallbladder motility
- Diet
- Erythropoietic protoporphyria[3]
Cholesterol gallstones develop when bile contains too much cholesterol and not enough bile salts. The following factors also play a role:
- Gallbladder contraction
- Incomplete and infrequent emptying concentrates bile
- Presence of proteins in the liver and bile causing either promotion or inhibition of cholesterol crystallization into gallstones
- Increased levels of the estrogen hormone may increase cholesterol levels in bile and also decrease gallbladder movement
Associated Conditions
- Diabetes mellitus type 2
- Obesity
- Pregnancy
- Gallbladder Cancer
- Gallbladder polyps
- Primary sclerosing cholangitis
- Porcelain gallbladder
- Rapid weight loss
- Constipation
- Eating fewer meals
- Low intake of:
On the other hand, wine and whole grain bread may decrease the risk of gallstones.[6]
Gross Pathology
On gross pathology, multiple small stones are commonly found or less commonly a solitary stone is seen. The smaller stones represent a higher morbidity since they can easily occlude the biliary tracts.[7]
Microscopic Pathology
On microscopic histopathological analysis, variable evidences of inflammation can be noted transmurally including neutrophils, which are characteristic in gallstone disease.[8]
