  • Look Inside

 In recent years, endoscopic sphincterotomy (EST) of the papilla of Vater has been widely accepted for endoscopic biliary tract surgery. An enlarged orifice of the distal common bile duct following EST allows to pass a larger caliber fiberoptic endoscope with a mechanism for tip control and an effective channel for irrigation and instrumentation into the biliary tract. In these considerations, we have developed new instruments and techniques for peroral cholangioscopy (PCS) under sliding tube guidance. This procedure was successfully accomplished in 44 of 61 patients with no complications.

 Peroral cholangioscopy (PCS) under sliding tube guidance is a new concept in biliary endoscopy and it is a safe and effective procedure though the technique is not so easy. It can offer a new dimmension in evaluating the duct system and can improve the management of their disease processes. Non invasive removal of stones in the biliary tract, especially in the intrahepatic bile duct, can be facilitated under visual control in conjunction with EST. When ductal tumors can be visually identified, biopsy or cytology can be performed under direct endoscopic guidance. The increasing use of this technique (PCS) can lead to early detection of tumors of the bile duct that may be overlooked or differentiated only with difficulty by conventional methods.
