Abstract

Direct visualization in bile duct and pancreatic pathologies has been shown to be beneficial in patients in whom previous techniques have failed. The development of the SpyGlass system has led to increased use of cholangioscopy. Being beneficial in patients with difficult gallstones and indeterminate biliary lesions, it also allows the visualization of stones not visible by other methods, the placement of a guidewire through difficult strictures and the selective cannulation of the intrahepatic and cystic ducts. It is also proving its usefulness in research applications such as the treatment of stenosis of primary and post-liver sclerosing cholangitis, evaluation of hemobilia, and guided radiofrequency ablation of intraductals. In addition to being clinically useful, cholangioscopy can also be cost-effective by limiting the number of repeat procedures. Cholangioscopy generally has similar complication rates compared to other standard techniques, but higher rates of cholangitis have been reported, this could improve with the use of prophylactic antibiotic therapy.
