A 78-year-old man who had previously undergone a cholecystectomy was admitted with symptoms of obstructive jaundice and cholangitis. The endoscopic ultrasound (EUS) showed a hypoechoic mass in the distal common bile duct (CBD) with no signs of vascular invasion or metastatic nodes (●" Fig.1). The patient underwent endoscopic retrograde cholangiopancreatography (ERCP), which revealed a filling d...

BACKGROUND AND STUDY AIMS Current evidence supporting the efficacy of peroral cholangioscopy (POC) in the evaluation and management of difficult bile duct stones and indeterminate strictures is limited. The aims of this systematic review and meta-analysis were to assess the following: the efficacy of POC for the therapy of difficult bile duct stones, the diagnostic accuracy of POC for the evalu...

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...

During laparoscopic cholecystectomy, unexpected findings may mandate immediate intraluminal biliary visualization for safe patient management. We evaluated percutaneous cholangioscopy in two whole-body donors. After preparation of the hilus, the sterile, single-use, 11 Fr, single-operator cholangioscope, with working channels for guidewire (or instruments) and irrigation (SpyGlass DS; Boston Sc...

CONTEXT Direct endoscopic visualization of biliopancreatic duct is certainly one of the greatest advances of therapeutic endoscopy. The use of a single-operator cholangioscopy platform (SpyGlass) is a promising technique in the evaluation of diseases such as indeterminate biliary stricture and giant choledocholitiasis. This is the first Brazilian case series using this technology. METHODS We ...
