Abstract

Background and Aims Cholangiopancreatoscopy for evaluating pancreaticobiliary pathology is currently limited by suboptimal optics. The aim of this study was to characterize the operating characteristics of per-oral video cholangiopancreatoscopy with narrow-band imaging (POVCP) findings in indeterminate pancreaticobiliary disease and to describe their association with neoplasia. Methods Data from consecutive patients undergoing POVCP for the evaluation of indeterminate pancreaticobiliary disease at a single tertiary care center were analyzed. Two experienced investigators had previously agreed on POVCP findings and terminology that were documented in endoscopy reports. Endoscopic procedural data from POVCPs performed between January 2006 and April 2015 and clinical data were abstracted from the endoscopic database and electronic medical records. Study endpoints included tissue-proven neoplasia or benign disease with ≥1 year of follow-up. Results A total of 109 patients were identified; 13 were excluded because of the presence of stone disease, known pancreaticobiliary malignancy, or presumed benign disease with ≤1 year of follow-up. Most patients (85%) underwent POVCP for biliary disease and 15% underwent POVCP for a pancreatic cause. Tortuous and dilated vessels (P <.001), infiltrative stricture (P <.001), polypoid mass (P =.003), and the presence of fish-egg lesions (P =.04) were found to be significantly associated with neoplasia. The overall POVCP impression had a high sensitivity (85%) and negative predictive value (89%) in assessing for the presence of neoplasia. Conclusions Per-oral video cholangiopancreatoscopy is effective in the evaluation of indeterminate pancreaticobiliary disease. Tortuous and dilated vessels, infiltrative stricture, polypoid mass, and the presence of fish-egg lesions are significantly associated with neoplasia.
