摘要
Choledochoscopy,or cholangioscopy,is an endoscopic procedure for direct visualization within the biliary tract for diagnostic or therapeutic purposes.Since its conception in 1879,many variations and improvements are made to ensure relevance in diagnosing and managing a range of intrahepatic and extrahepatic biliary pathologies.This ranges from improved visual impression and optical guided biopsies of indeterminate biliary strictures and clinically indistinguishable pathologies to therapeutic uses in stone fragmentation and other ablative therapies.Furthermore,with the evolving understanding of biliary disorders,there are significant innovative ideas and techniques to fill this void,such as nuanced instances of biliary stenting and retrieving migrated ductal stents.With this in mind,we present a review of the current advancements in choledochoscopy with new supporting evidence that further delineates the role of choledochoscopy in various diagnostic and therapeutic interventions,complications,limitations and put forth areas for further study.
