The investigators are evaluating the use of a SpyBite biopsy forceps for tissue diagnosis when compared to standard biopsy techniques.

Condition Intervention
Accuracy of Tissue Diagnosis
Procedure: Endoscopic Retrograde Cholangiopancreatography (ERCP)with cholangiopancreatoscopy and stricture sampling

Study Type: Observational
Study Design: Observational Model: Case-Crossover
Time Perspective: Prospective
Official Title: Prospective Evaluation of the Accuracy of Spybite Biopsy Forceps for the Tissue Diagnosis of Lesion of the Pancreatobiliary System. ( Part of the "The Clinical Utility of Cholangioscopy and Pancreatoscopy in the Diagnosis and Treatment of Pancreaticobiliary Disorders" Study)

Further study details as provided by University of Florida:

Primary Outcome Measures:
  • accuracy of SpyBite biopsy forceps [ Time Frame: at scheduled Endoscopic Retrograde Cholangiopancreatography (ERCP) visit approximately 4-5 hours. ] [ Designated as safety issue: No ]
    The accuracy of the Spybite Biopsy forceps will be compared to cytology brush and RJ3 biopsy forcep sampling of any stricture found on Endoscopic Retrograde Cholangiopancreatography (ERCP)

Estimated Enrollment: 25
Study Start Date: November 2006
Estimated Study Completion Date: September 2016
Estimated Primary Completion Date: September 2016 (Final data collection date for primary outcome measure)
