Assessment of Cholangio-pancreatoscopy for the Diagnosis and the Treatment of Biliary and Pancreatic Diseases

Assessment of Cholangio-pancreatoscopy for the Diagnosis and the Treatment of Biliary and Pancreatic Diseases Trial " EASYSPY "

The biliary and pancreatic tumors are rare but the prognosis is pejorative. It was difficult to have histology of these tumors as the samples taken during ERCP were performed under " blind " radiology control. So the diagnostic accuracy was insufficient.

The arrival of A new optic fiber endoscope used by only one operator had improved the diagnostic of bilio-pancreatic diseases. However this technology with optic fiber quickly had proved outdated for several reasons: poor manoeuvrability, perfectible optical vision, optical fibers fragility and cost.

A new generation of endoscopes with digital vision appeared and would allow an increase in diagnostic accuracy related to better vision and manoeuvrability.

The purpose of the study is to assess the interest of the cholangio pancreatoscopy performed with digital vision.
