ERCP was at least for last decades the only diagnostic possibility for diagnostic of biliary patology, especially for biliary strictures. Evaluation of indeterminate biliary strictures by brush cytology and intraductal biopsies is limited by low sensitivity.
The utility of SpyGlass peroral cholangioscopy for diagnosis of malignant biliary strictures is already clear. It provides much more relevant and more accurate information about biliary patology and even is helpfull in many complicated terapeutic situations.
Our aim was to study the efficassy of SpyGlass peroral cholangioscopy.
