Primary Amyloidosis Manifesting as Cholestatic Jaundice after Laparoscopic Cholecystectomy

Abstract EN

A 71-year-old female patient with cholelithiasis who had undergone laparoscopic cholecystectomy was admitted with obstructive jaundice (total bilirubin ~6 mg/dL) three months later.

An ERCP was performed, in which a gallstone was found, followed by a sphincterotomy and cleansing of the bile duct.

Due to deterioration of jaundice (>25 mg/dL), a new, unsuccessful ERCP and stent placement was carried out.

Because of ongoing cardiac failure, she underwent an echocardiogram which revealed restrictive cardiomyopathy possibly due to amyloidosis.

A liver biopsy was performed, which was positive for amyloid deposits in the liver, and the diagnosis was confirmed by the detection of monoclonal λ IgG protein in urine.

The patient’s jaundice gradually deteriorated and she died one week later from hepatic insufficiency.
