[Percutaneous transhepatic cholangioscopy with an 8.5 French endoscopic catheter. Technic and preliminary results].
The authors describe their preliminary personal experience in bile duct endoscopy with a very small diameter catheter (8.5 F) much less traumatic than traditional choledochoscope (15 F). The CE can be reutilized after sterilization; an angiographic guide wire up to 0.042" can be introduced in the operating channel. The CE was used in 3 patients with uncertain cholangiographic diagnosis. Instrument introduction is facilitated when simple technical manoeuvres are followed; there were no difficulties in report interpretation. An experienced interventional radiologist and an endoscopist are needed to handle the instrument. Cytologic sample, biopsy and gallstone lithotomy instruments will increase diagnostic and therapeutic possibilities of the system: for this a wider CE use in the immediate future to complete interventional radiology manoeuvres can be expected.
