gallstones presentation
Asymptomatic Dyspeptic symptoms (flatulent dyspepsia) Biliary colic Acute cholecystitis Empyema Perforation Jaundice (Mirrizi’s Syn.) Gallstone Ileus
what is Choledocho-lithiasis
is the presence of a gallstone in the common bile duct
consequences of Choledocho-lithiasis
Post-cholecystectomy pain Obstructive jaundice (painful) Pain, jaundice, dark urine, pale stool, pruritus, steatorrhoea Acute pancreatitis Ascending cholangitis (Charcot’s triad)
gallstones investigations
