Peroral cholangiopancreatoscopy (PCPS) using a mother and babyscope was attempted
in 30 cases and the duct systems were successfully inspected in 25 cases. This procedure
should be useful in cases with biliary and pancreatic diseases if the bending system
and biopsy channel of the babyscope can be improved. Peroral direct cholangioscopy
(PDCS) using four kinds of forward-viewing small-caliber fiberscopes was successfully
employed in 14 of 22 cases. These instruments have a biopsy channel as well as an
air-supplying and an aspiration channel, so that a stone can be removed with a basket
catheter under visual control. PDCS should become valuable therapeutically in bile
duct diseases if the fiberscope can be improved.
