ERCP WITH ELECTRONIC ENDOSCOPE

Abstract

We compared the results of ERCP with electronic endoscope with those with conventional fiberendoscope. The electronic endoscope used in this study was a JF-V10 (OLYM-PUS), and the conventional fiberscope was a JF-1T10 (OLYMPUS). The number of cases which underwent ERCP with the JF-V10 and the JF-1T10 was 327 and 142, respectively. The specification of the tip deflection of the JF-V10 is similar to that of the JF-1T10. Using the JF-V10, a success rate of pancreatography was 93.4% and that of cholangiography was 87.1%. Using the JF-1T10 the respective rate were 93.9% and 91.9%. The time required for ERCP with the JF-V10 was 12 minutes 8 seconds, and with the JF-1T10, 11 minutes 55 seconds. We could perform treatment (the endoscopic papillotomy, cytology, lithotomy, biopsy, etc.) with the JF-V10 quite successfully. Actual ability of this instrument is comparable to that of the conventional fiberscope employed. This instrument has great advantage with regard to the training of medical personnel in endoscopic treatment. Also, the large TV monitor lessens the burden on the endoscopist. To facilitate the wide use, the tip of the electronic endoscope should be further shortened.
