(A) Cholangiography shows an irregular filling defect in the proximal bile duct with placement of biopsy forceps distal from the mass. (B) Cholangiography shows a filling defect in the proximal bile duct with placement of biopsy forceps in a central area of the defect. The biopsy forceps were easily placed along a guidewire that was passed through a hole in the silicone tube. (C) Attachment of a silicone tube on the proximal shaft of the biopsy forceps. (D) The silicone tube has a small hole that permits passage of a guide-wire and easy passage of forceps into the working channel and bile duct.

Low-power microscopic examination reveals a fragment of well-differentiated adenocarcinoma (circle mark) on a background of necrotic debris. The amount of tumor mass obtained by endoscopic retrograde cholangiopancreatography (ERCP) in (A) and (B) indicates that (B) was superior for sampling of sufficient tissue for histologic diagnosis (hematoxylin-eosin stain; ×40).
