NCT01815619

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).

Conditions

Outcome Measures

Primary Outcomes (1)

  • Diagnostic accuracy of cholangioscopy-directed biopsies of bile duct strictures

    The primary endpoint of the study is to compare the diagnostic accuracy rates between two different methods used for processing specimens obtained from the bile duct.

    up to18 months

Secondary Outcomes (4)

  • Specimen evaluation

    up to18 months

  • Operating characteristics

    up to18 months

  • Costs difference between the onsite and offsite procedures

    up to 18 months

  • Number of biopsies to achieve diagnosis

    up to 18 months

Study Arms (2)

on-site evaluation of specimens by cytopathologist

EXPERIMENTAL

The specimen will be evaluated onsite by a cytopathologist during the procedure to render a diagnosis

Other: on-site specimen evaluation

off-site specimen evaluation

ACTIVE COMPARATOR

The specimen will be evaluated offsite by a cytopathologist during the procedure and render a diagnosis

Other: off-site specimen evaluation

Interventions

The specimen will be evaluated on-site by a cytopathologist during the procedure to render a diagnosis

on-site evaluation of specimens by cytopathologist

The specimen will be evaluated off-site by a cytopathologist

off-site specimen evaluation
