Clinical Evaluation of the Peroral Cholangioscopy Using a New Videoscope
Peroral cholangioscopy (PCS) has been performed in 22 cases using XCHF-B200 (Olympus Optical Co.) since June 1995 and in 77 cases using CHF-B20 (Olympus Optical Co.) after EST from Jan. 1989. XCHF-B200 has a longer rigid portion of distal end and a smaller channel diameter than CHF-B20. The successful rate of PCS using XCHF-B200 (82%) was lower than that of CHF-B20 (89%). The vascular pattern a...

expanded the horizons of interventional endoscopy [1]. Starting with rigid optical endoscopes that could access only either end of the digestive system, endoscopy evolved to enable visualization of the en− tire gastrointestinal tract with the devel− opment of capsule endoscopy and dou− ble−balloon enteroscopy [2]. However, the biliary−pancreatic system still re− mained a side track. The availab...
متن کاملA novel technique for peroral direct cholangioscopy.
Article Direct cholangioscopy has been possible since the 1970’s (1) but reliable intubation of the common bile duct (CBD) and second order ducts has limited the applicability of the technique. One of the limitations to accessing the ducts is the acute angulation between the duodenum and the CBD (2). Various methods have been employed to access the ducts including mother-and-baby endoscopes and...
متن کاملDirect peroral cholangioscopy using an ultrathin endoscope: making technique easier.
BACKGROUND Cholangioscopy is a useful tool for the study and treatment of biliary pathology. Ultrathin upper endoscopes allow direct peroral cholangioscopy (DPC) but have some drawbacks. OBJECTIVE The aim of the study was to evaluate the success rate of DPC with an ultrathin endoscope using a balloon catheter to reach the biliary confluence. MATERIAL AND METHODS Prospective observational st...

altered gastrointestinal anatomy is challenging because of the technical difficulties associated with accessing the papilla and the high rate of complications experienced when using a side-viewing duodenoscope [1]. The recently developed SpyGlass Direct Visualization System (Microvasive Endoscopy, Boston Scientific, Natick, Massachusetts, USA) can be passed through a forward-viewing endoscope b...
