not a lot of pancrease function leftcan get just a mildly elevated amylaseneed to go back to the history and see how much they are drinking and if they have ever had this before

differentiating cholecystitis from cholelithiasis

A

SEVERE CONSTANT PAINN/V/F

71

acute cholangitis

A

ascending infection of the biliary tract results from acute cholecystitis

72
Q

iii. Charcot’s Triad

A

acute cholangitis “ RUQ pain” Shaking chills & Fever” Jaundicesurgical emergency gall bladder out RIGHT NOW

73

44-147
