A 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 کاملClinical 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...
متن کاملPeroral cholangioscopy: new approach with a balloon enteroscope.
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 کاملPeroral cholangioscopy: use of a Roth Net retriever for difficult biliary stones.
Bile duct stones are routinely removed during endoscopic retrograde cholangiopancreatography (ERCP) with biliary sphincterotomy, using standard balloon or basket extraction techniques. However, in approximately 10%–15% of patients, bile duct stonesmay be difficult to remove owing to challenging access to the bile duct, large bile duct stones (>15mm in diameter), intrahepatic stones, or impacted...
متن کاملSuccessful biliary drainage with peroral direct cholangioscopy in a patient with Roux-en-Y hepaticojejunostomy for congenital biliary dilatation.
The diagnostic and therapeutic effectiveness of combined double-balloon endoscopy with a short endoscope and peroral direct cholangioscopy with an ultraslim endoscope in patients who have altered gastrointestinal anatomy has been demonstrated [1–5]. We describe successful biliary drainage with a short double-balloon endoscope and peroral direct cholangioscopy in a patient who had cholangitis af...
