ERCP, endoscopic papillotomy and gallstone removal by JFB2 Olympus and PFSB 1200 Machida.

ERCP is now used as routine technique and has provided a useful tool for both diagnostic and therapeutic purposes in diseases of the biliary tract. Until now this examination has been performed throughout the world including Italy, using preferably an Olympus JF and JF B2 sideviewing duodenoscope. In addition to 727 ERCP and 55 papillotomies performed using this instrument we have also employed a convertible endoscope Machida PFSB 1200; this fiberscope, with which front and side views are possible, can be used in the study of the oesophagus, stomach, duodenum, cannulation of the papilla of Vater and papillotomy. They results obtained and advantages offered by this instrument will be discussed. Since this endoscope is not usually employed, at least in Europe, for these purposes, we considered it of interest to report on the 251 ERCP and 9 papillotomies including stone removal performed in our department with the Machida PFSB 1200.
