Summary

The aim of this prospective national multicenter randomized study is to compare, during an ERCP for VBP stenosis, the sensitivity of two biliary brushes: the INFINITY® vs the RX Cytology Brush® The main objective is the comparison of the rates of positive diagnosis of biliary brushing in cases of adenocarcinoma stenosis The total number of subjects required: 50 (25 patients per group) Duration of the inclusion period: 2 years Duration of participation for each subject: from 7 days to 12 months (in case of negative initial withdrawal) Total duration of the study: 3 years

Conditions

  • Biliary Stricture
  • Jaundice, Obstructive

Interventions

DEVICE

Biliary brushing with the RX Cytology brush, Boston Scientific

Biliary brushing during ERCP: * Performing a dozen back and forth movements in the stenosis * Bile aspiration if possible, by the catheter of the brush for cytological analysis * The contents of the brush will be spread over 3 blades (numbered) then sectioned and placed in cytolit with the contents of the tubing of the brush flushed with a few cc of cytolit. Each brush in a numbered pot. Blades 1,2 and 3 +/- bile 1 joined to pot n ° 1; blades 4,5 and 6 +/- bile 2 joined to pot 2 * In the event of technical failure (impossibility of accessing the stenosis with the first or second brush, impossibility of removing the brush), the patient will be considered to have failed for this brush (absence of pathological material brought back)
