PERORAL CHOLANGIOPANCREATOSCOPY USING A NEW VIDEOSCOPE (CHF-Y0012)

Aims:

Peroral cholangioscopy (PCS) and pancreatoscopy (PPS) using videoscope (CHF-BP260, CHF-B260, Olympus Co.) was performed since 2002 in our hospital. Endoscopic image is a good, however it is sometime easy to broken. We recently started to use a new videoscope (CHF-Y0012, Olympus Co. Tokyo). In this study, we evaluate with the endoscopic image for diagnosis of the biliary and pancreatic disorder.

Methods:

Since Jun. 2016, PCS and PPS using a new videoscope (CHF-Y0012) were performed in 49 cases (44 cases are the bile duct stenosis and 5 are intraductal papillary-mucinous neoplasm). The outer diameter of CHF-Y0012 is 3.3 mm. It has the scope bending function (up 70 °and down 70 °) and the channel diameter is 1.3 mm. It is inserted into the bile duct and the main pancreatic duct under fluoroscopic guidance. Physiological saline is continuing to inject during observation. Endoscopic photographs were taken using the EVIS-290 systems (Olympus Co.).

Results:

PCS and PPS using CHF-Y0012 were successful in all cases. One case of the malignant biliary stenosis (IBMN) could not observe the main lesion because of the intrahepatic stenosis. Endoscopic picture obtained were clearly in all cases.

This procedure was performed safely in all the cases without any complication.

Conclusions:

PCS and PPS using CHF-Y0012 are very useful for the diagnosis of the biliary and pancreatic disorder.
