Figure 1 Biliary biopsy forceps and the procedural steps of biliary biopsies.
A: Radial JawTM 4 Biopsy Forceps. The cup diameter of these forceps is 2 mm. B: The image perspective in cholangiography. Biliary biopsy was performed with a Radial JawTM 4. C: The specimen was obtained with 2-mm biopsy forceps (X 200, hematoxylin eosin (HE) staining). Papillate lines were formed by biliary cancer cells. D: SpyBite. The cup diameter of these forceps is 1 mm. E: Biliary biopsy was performed with the SpyBite system through the MTW endoscopic retrograde cholangiopancreatography (ERCP) catheter (arrow: the tip of a SpyBite, arrowhead: the tip of an MTW ERCP catheter). F: The specimen was obtained by 1-mm biopsy forceps (X 400, HE stain). Papillate lines were formed by columnar biliary cancer cells.
