When ERCP was unsuccessful by the use of JF-B, it was often helpful to substitute a slender, frontal viewing f iberscope (GIF-P2, Olympus) for the former instrument, Here is described the significance of using GIF-P2 in ERCP. Out of 15 cases in which ERCP with GIF-P2 was attempted, the cases of successful cholangiography were 11, and those of pancreato-graphy were 7, thus well supplementing the low rate of cholangiography by the use of a lateral viewing instrument, JF-B. Indications of using GIF-P2 for ERCP will be following:1) Unsuccessful cannulation into the orifice of papilla by JF-B.2) Unsuccessful case of cholangiography by JF-B.3) ERCP for cases with stenosis of the esophagus, the stomach and the upper duodenum.4) ERCP in gastrectomized cases with Billroth II anastomosis etc.
