Brief Summary
This study will test two different methods for processing biopsy specimens taken from the bile duct. Patient;s who are asked to participate int his study have a stricture in the bile duct that needs a single operator cholangioscopy-guided biopsies during endoscopic retrograde cholangiopancreatography (ERCP) so that a diagnosis can be made. Standard of care includes performing single operator cholangioscopy-guided biopsies in the bile duct and sending the tissue to the lab for testing to make a diagnosis. Using this method the investigators can establish a diagnosis only about 50% of the time. The investigators believe that if a cytopathologist is available in the endoscopy suite during the procedure to evaluate the biopsy specimens onsite, the investigators can improve the diagnostic accuracy. The purpose of this study is to compare two methods for processing biopsies obtained from the bile duct (Onsite vs. Offsite).
