Innovative use of a 3-Fr microcatheter for precision guidewire placement with digital single-operator cholangioscopy for pancreaticobiliary drainage (with video).

ABSTRACT: Biliary and pancreatic tract stenosis are hallmark symptoms in pancreaticobiliary diseases, transcending malignancy. Endoscopic techniques are pivotal for biliary/pancreatic drainage; however, challenging scenarios arise when attempting to pass a guidewire (GW) through obstruction. Cholangioscopy-assisted GW placement has proven valuable, but challenges persist in its execution, particularly in maneuvering the GW through cholangioscopy. Therefore, we explored the integration of a 3-Fr microcatheter into cholangioscopy with the aim of enhancing direct visualization and offering a super-selective approach. When GW manipulation under a digital single-operator cholangioscope (D-SOC) guidance was still unsuccessful in a resistant obstruction, the 3-Fr microcatheter was introduced. This techniqu
