Cholangioscopy-assisted guidewire placement is reported to be a useful method for endoscopic biliary drainage that is made difficult by complex strictures and obstructions [1] [2] [3] [4] [5]. However, the guidewire sometimes becomes misdirected because of the lack of contrast-filled images. With the aim of improving safety and certainty, we present two practical cases that employ a novel technique using an over-the-wire microcatheter through digital intraductal cholangioscopy (IDC) (SpyGlass DS; Boston Scientific, Natick, Massachusetts, USA).

Case 1 involved a 72-year-old woman with hilar cholangiocarcinoma who underwent endoscopic biliary drainage for segmental cholangitis. The cholangiogram showed complete obstruction of the left hepatic duct ([Fig. 1]). Although direct visualization with IDC allowed advancing the 0.025-inch guidewire over the obstructing tumor in the left hepatic duct, the guidewire lost the pathway to the left intrahepatic bile duct. The 3-Fr outer sheath of a basket catheter (MicroCatch; MTW Endoskopie, Düsseldorf, Germany), which can be inserted into the SpyGlass DS, was introduced as a microcatheter in order to inject contrast medium and assist guidewire manipulation. The contrast-filled image of the left intrahepatic bile duct allowed successful negotiation ([Fig. 2]), followed by replacement of the endoscopic nasobiliary drainage tube ([Video 1]). Case 2 involved a 79-year-old man with acute cholecystitis. The cholangiogram showed complete obstruction of the cystic duct ([Fig. 3]), which prevented guidewire advancement under fluoroscopic imaging. The orifice of the cystic duct was visualized using the SpyGlass DS, then the guidewire with a 3-Fr endoscopic nasobiliary drainage tube (Daimon-PTCD set, Hanaco Medical, Saitama, Japan), another microcatheter that may be used through the SpyGlass DS, was advanced into the cystic duct ([Fig. 4]). At one point when the guidewire was advanced in an unknown direction, contrast injection through the microcatheter showed clearly that the guidewire had penetrated the peritoneal cavity ([Fig. 5]). The microcatheter also assisted with maneuvering of the guidewire to correct its course, resulting in successful access to the gallbladder, completed by insertion of a plastic stent ([Video 1]).

Cholangioscopic operation with a microcatheter offers advantages both for obtaining selective contrast-filled images and for delicate manipulation of the guidewire as performed in selective angiographic examinations.
