  • Abstract
  • Look Inside

 The authors with cooperation of the Fuji Photo Optical Co., LTD. manufactured a new fiber choledochoscope “FT-SF” with an idea to improve the practical aspect of handling the instrument. It was intended to make easier the operation of the stone forceps or insertion of the catheter during irrigation and inspection. For this purpose, the shaft of the fiberscope was much shortened to make smooth the acute-angle application of the forceps and it was devised also not to damage the forceps-hole of the shaft.

 The Fujinon “FT-SF” was used in 25 patients on 12 occasions of intraoperative choledochoscopy and 34 occasions of postoperative choledochoscopy. It has been thus confirmed that the intraductal inspection is possible by this at the level of the tertiary hepatic duct or even periphery and that the litholapaxy by this is effective for not only common duct residual stone but intrahepatic stone as well. No complication due to the new fiber choledochoscopy was observed.
