Development of a New Immunochemistry Method Using Antibodies of Proteins Related Bile Duct Cancer

NCT03708445 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 240

Last updated 2020-02-05

No results posted yet for this study

Summary

The sensitivity of brushing cytology used to distinguish the cause of biliary strictures is low and clinical usefulness is not secured. The aim of this study was to develop a new differential staining method for cytology which is difficult to differentiate by the conventional staining method using biliary cancer related protein expressed only in bile duct cancer.

Conditions

  • Bile Duct Obstruction, Extrahepatic

Interventions

DIAGNOSTIC_TEST

Cytology staining

Two staining will be performed in cytology specimens obtained from same patient. The cytology specimen will be obtained through brushing cytology using endoscopic retrograde cholangiopancreatography 1. conventional cytology staining method 2. new cytology staining method using antibody of aminoacyl-tRNA synthetases
