Bile and Bile Duct/Pancreatic Duct Brushings Database for Patients With Pancreato-biliary Stricture

March 29, 2017 updated by: Mansour Parsi, MD, The Cleveland Clinic

The purpose of this study is to create a long-term storage of bile and brushings of pancreato-biliary duct in patients diagnosed with pancreato-biliary stricture for future research.

Recently, a lot of research has been done to test for certain markers in the bile and brushings to detect cancer in a stricture. The samples will be used to measure biomarkers (proteins) in biliary diseases.

Detailed Description

Recently, a lot of research has been done to test for certain markers like fluorescence in situ hybridization (FISH), digital image analysis (DIA), and quantifiable morphometric results in biliary stricture brushings. Recently, polysomy FISH has been studied as a promising marker in predicting cancer in a pancreato-biliary stricture. Many genetic, epigenetic, and protein alterations arise during pancreaticobiliary tumor process. The types of markers that have been commonly evaluated as diagnostic assays are mutations, chromosomal gains and losses, and DNA methylation alterations. However there are only a few studies in this area. Testing for these markers can help determine whether the narrowing or stricture in your bile duct is cancer or not.
