When the Going Gets Tough: Utilization of SpyGlass, or Drainage Followed by Stone Removal / 대한췌담도학회지

ABSTRACT

At least 90% of stones are extracted after conventional endoscopic retrograde cholangiopancreatography. However, some cases are still difficult to manage completely. We describe some methods of removing difficult common bile duct stones through a single-operator cholangioscopy using SpyGlass system, direct peroral cholangioscopy, and temporary biliary stenting.
