[The technical requirements for percutaneous fine-caliber cholangioscopy. Experimental experiences with an animal model].
A total of 115 percutaneous fine-calibre cholangioscopies were performed in an animal model, using different types of fine-calibre cholangioscopes of 0.8 to 2.8 mm. diameter. Additional properties of single endoscopes included different flexibility, deflectability of the tip, occlusion balloon and working channel. Due to the low steerability of the instruments used, a coaxial guidance by an introducing sheath was mandatory for sufficient imaging quality. Besides flexibility and provision of a working channel, no other properties contributed to a successful endoscopic inspection of the biliary system.
