Endoscopic retrograde cholangiopancreatography (ERCP) is used to examine patients with biliary tract obstruction or structure for possible malignancy. Biopsies and cytologic specimens are obtained at the time of ERCP. Cytologic analysis complements biopsy by sometimes detecting malignancy in patients with a negative biopsy. Nonetheless, a number of studies suggest that the overall sensitivity of bile duct brushing and bile aspirate cytology is quite low. FISH is a technique that utilizes fluorescently labeled DNA probes to examine cells for chromosomal alterations. FISH can be used to detect cells with chromosomal changes (eg, aneuploidy) that are indicative of malignancy. Studies in our laboratory indicate that the sensitivity of FISH to detect malignant cells in biliary brush and bile aspirate specimens is superior to that of conventional cytology.

Specimen Type: Bile duct aspirate, bile duct brushing, hepatobiliary
aspirate, or hepatobilary brushing
Container/Tube: Separate ThinPrep vial containing 20 mL PreservCyt or
CytoLyt solution (Supply T536) for each Specimen

1) If performing local cytology before processing specimen, aliquot
half of the specimen into another ThinPrep vial.

2) Retain 1 aliquot for local cytology and submit the second aliquot
for analysis at Mayo Medical Laboratories.

3) Submission of the residual specimen (after processing for cytology)
may compromise the sensitivity of the test.

Forms: If not ordering electronically, submit a Pathology/Cytology
Request Form (Supply T246) with the specimen.
