Gallstones & Jaundice
Gallstones
24% of women and 12% of men may develop local infection + cholecystitis
Jaundice
Definition jaundice, also known as icterus I the yellow discolouration of mucous
Type of gallstones membrane, sclera + skin due to the accumulation of bilirubin
Cholesterol – light yellow to dark green, usually solitary, with a dark, central spot. Need to Jaundice may be seen @ a [>2.5-3.0mg/dl/42.8-51.3mmol/l]
be > 80% cholesterol by weight Aetiology
Pigment- also known as bilirubin stones, are dark/black and numerous. Predominately Pre-hepatic Intrahepatic Post-hepatic
composed of bilirubin and calcium salts that are found in bile. Contain < 20% cholesterol Crigler-Najjar syndrome Viral + drug induced
Mixed usually brown in colour, contain 20-80% cholesterol, also made up of calcium Gilbert’ syndrome hepatitis Gallstones in bile duct
carbonate and other bile pigments Haemolysis e.g. Alcohol liver disease Pancreatic cancer
Gallstones + bile duct obstruction cholangitis (due to stagnate bile causing mucosal thalassaemia, sickle cell Hepatic cirrhosis Schistosomiasis
